(5 reviews) ## Knock Reviews ### 1. Knock continues to enable our teams at Vidyard to create and deliver new notifications in hours **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Computer Software | Mid-Market (51-1000 emp.) **Reviewed Date:** November 15, 2023 **What do you like best about Knock?** Knock makes it easy for our organization of multiple teams to jump in and create new email, in-app, and push notifications. The visual template editor allows our developers to quickly create and modify new notifications, and gives us the ability at a glance to check the behaviour of our existing notifications. Our contacts are fantastic and were quick to answer our questions and provide new features for us when requested. Their insight and availabilty allowed us to implement Knock into our existing (large) product before our set deadline. **What do you dislike about Knock?** Knock is very developer focused and still requires a decent amount of technical know-how to operate/trigger notifications. This is fine, but we'd like the ability to make email design/creation more accessible to our designers. The ability for developers to create custom drag and drop components (like the existing out of the box button component, for example) would enable us to provide building blocks to our designers to use in the creation and design of new emails. **What problems is Knock solving and how is that benefiting you?** Our original notification infrastructure required significant time investment to create new notifications. Each new in-app notification required backend work and also required us to modify each of our frontends that host a notification feed (ex. website, chrome extension). When all this work is measured, implementing a new notification could take anywhere from 3-4 weeks or even longer depending on the complexity. Knocks backend HTML rendering and template editor has made it easy for us to create new notifications and push out updates to existing ones. Instead of spending upwards of a month on creating and modifying new notifications, we can now do it in hours or even minutes. ### 2. Knock is an excellent upcoming multi-channel notification service **Rating:** 3.0/5.0 stars **Reviewed by:** Verified User in Computer Software | Small-Business (50 or fewer emp.) **Reviewed Date:** August 02, 2023 **What do you like best about Knock?** Knock makes it absolutely trivial to achieve multi-channel notification support in your app. It supports emails, SMS, Slack, and everything else any reasonable app could ask for. It makes delegating copy and design to others easy through the online template editor. **What do you dislike about Knock?** Knock has some issues, particularly with bugs and production readiness. They have a sub-par Golang client that makes heavy use of untyped data, and their payload format doesn't support strong typing. Knock has no clean way to manage payload specs in git, despite having environment support. Their environment system lacks branching capabilities, meaning many developers must share the development environment which can sometimes cause issues. The commit system is a good idea, but lacks the info required to be truly useful. It doesn't show the author of a commit or what was changed. **What problems is Knock solving and how is that benefiting you?** Knock solved our problems with having multiple vendor implementations maintained by us lying around in our repository. These would frequently become out of sync and our codebase had no easy way to have multi-channel workflows. ### 3. Never building notification infrastructure again **Rating:** 5.0/5.0 stars **Reviewed by:** Alexander K. | Chief Executive Officer, Small-Business (50 or fewer emp.) **Reviewed Date:** May 04, 2023 **What do you like best about Knock?** Until discovering Knock, I used to dedicate weeks of engineering resources to building out proper notification infrastructure. I recently tried Knock for a new project and was blown away by how quick and seamless getting notifications up and running was. Focusing on business logic and having Knock handle all things infra is a massive boost in value. I'm moving all of my current projects over to Knock and will be using Knock for any new projects that come along. Knock is now my go-to recommendation for notification infra. **What do you dislike about Knock?** There's not much to dislike. The only thing we've given (well-received) feedback on was subscribing users to types of notifications (e.g. when a notification of type X goes out, it should reach an audience subscribed to that type). The easy workaround is to bulk-send to all relevant users on our end in batches of 1000, which has been working fine for us. **What problems is Knock solving and how is that benefiting you?** We needed an in-app notification feed along with the infrastructure to send push notifications to both android and iOS. Knock slotted in as a perfect solution that met all of our requirements. The ability to flexibly use their in-app feed components saved us so much time. ### 4. Streamlined Notifications, Exceptional Service, and User-friendly Experience! **Rating:** 5.0/5.0 stars **Reviewed by:** Aaron V. | Small-Business (50 or fewer emp.) **Reviewed Date:** May 02, 2023 **What do you like best about Knock?** Knock has been an excellent choice for our notification messaging needs. We appreciate the ease of setup and the user-friendly interface, which allows our team to create custom workflows and templates quickly. It's great that Knock consolidates all our customer interactions across different messaging channels into one accessible platform. The team behind Knock has been exceptional – responsive, open to feedback, and dedicated to implementing improvements based on our suggestions. **What do you dislike about Knock?** We genuinely have not encountered any issues while using Knock. Both the platform and the team have consistently met and exceeded our expectations. We've discussed general improvements, feedback and nice to haves with the platform and the team have been ontop of it with letting us know where it fits in their priority and roadmap. **What problems is Knock solving and how is that benefiting you?** Knock addresses the challenge of managing customer notifications across multiple messaging channels by offering a centralised platform. This consolidation simplifies the process, enabling our team to create and manage custom workflows and templates for various notification scenarios efficiently. As a result, we save time and resources while maintaining a consistent and effective communication strategy with our customers. ### 5. Easy-to-Use Product with Great Customer Service and Reliability **Rating:** 4.5/5.0 stars **Reviewed by:** Kunj M. | Tech Lead, Mid-Market (51-1000 emp.) **Reviewed Date:** May 02, 2023 **What do you like best about Knock?** Knock's developer-centric approach makes implementing and tailoring to specific needs effortless. Setting up multiple environments that simulate application environments and testing notifications is a breeze, making it an ideal notification platform for our needs. The product is complemented by excellent developer documentation and outstanding customer service that goes above and beyond, especially the CEO Sam Seely. The Knock team responded quickly during the implementation process and provided detailed beta features with accompanying developer documentation. The platform's workflow engine is a standout feature, offering flexible and extensible flows for notification types through integrations with notification providers and functions like batching. But what sets Knock apart is its exceptional team. From the onboarding process and beyond, the team's immeasurable assistance and open communication have instilled unparalleled confidence in the product. Knowing that any arising issues will be addressed promptly and effectively is reassuring. **What do you dislike about Knock?** Our experience with Knock has been seamless. In the rare instances where we encountered issues, such as bugs or feature requests, the team was readily available to address them. The bugs, although minor, were resolved within hours of our report. Moreover, the team was open to our feature requests and even incorporated some of our suggestions into their roadmap, which was greatly appreciated. Overall, the responsive support from the team has made using Knock a hassle-free experience. In full transparency, we did experience a rare outage with Knock that went unnoticed for a few hours. However, the team quickly took ownership of the issue and immediately implemented plans to prevent similar occurrences. They even provided a proper root cause analysis (RCA) and extended night support during recovery. Evidently, the team takes accountability for their platform's performance and is committed to delivering a reliable and resilient service. We appreciate their dedication to ensuring customers are always satisfied with their product and support. **What problems is Knock solving and how is that benefiting you?** Knock's notification platform has been invaluable in managing the complexities and nuances of notifications within our platform. One of the most significant problems they have addressed is notification fatigue, which they tackle through their batch function. In addition, Knock's platform streamlines the process of sending notifications to various channels, while improving the internal workflow for adding and updating notifications. This has made a significant impact on our team's productivity, as we are now able to deliver new notifications in a matter of days instead of weeks. Overall, Knock has provided an efficient and effective solution to a critical aspect of our platform, making it easier for us to manage notifications and enhance the user experience. ### 6. Quick to set up, easy to understand, and a communicative team **Rating:** 4.5/5.0 stars **Reviewed by:** Melissa K. | Software Engineer, Computer Software, Small-Business (50 or fewer emp.) **Reviewed Date:** April 27, 2023 **What do you like best about Knock?** Once you have one notification workflow set up in Knock, it is extremely fast to set up and tweak new ones and to update old ones. The UI is fairly straightforward and easy to understand, with simple monitoring of messages and users. And I love that it's super easy to switch between Development and Production and that there are safeguards for committing updates to prod. The few times we've needed to reach out to the Knock team with questions, they responded promptly and were helpful. **What do you dislike about Knock?** The message template editor for emails is pretty basic. While there is syntax highlighting, I can't say I enjoy using it. But this is a very minor complaint and ultimately it does get the job done! **What problems is Knock solving and how is that benefiting you?** We use Knock to manage both our in-app notifications and email notifications that result from actions users take while using our product. It's great to be able to manage both of these in one place. The Development environment works well for testing before we commit our notification workflows to Production, and it's helpful to be able to turn them off and back on quickly if we need to handle a bug. ### 7. Easy to use product and great customer service **Rating:** 5.0/5.0 stars **Reviewed by:** Chamila A. | Mid-Market (51-1000 emp.) **Reviewed Date:** April 27, 2023 **What do you like best about Knock?** Hard to name just one thing! We loved the ease of use, fantastic developer documentation, and above-and-beyond customer service. Throughout the implementation, Knock was incredibly responsive whenever questions came up. They also regularly released beta features to us that were delivered on time and came with detailed developer documentation. **What do you dislike about Knock?** We didn't have any issues using Knock. Whenever we had problems (bugs or feature requests), we reached out to the team and shared our concerns. For bugs (which were minor), the team usually fixed them within hours. For feature requests, they incorporated some of our suggestions into their roadmap. Some of our feature requests included integrating with more channels, supporting translations (which has now been released), and more advanced workflow management. **What problems is Knock solving and how is that benefiting you?** Making it easier to send notifications to a variety of channels, as well as improving the workflow internally for adding/updating notifications. Our team is able to deliver a new notification in a matter of hours now (instead of days or weeks). ### 8. Extensible, scalable, observable and truly reliable **Rating:** 5.0/5.0 stars **Reviewed by:** Taylor M. | Engineering Team Lead, Mid-Market (51-1000 emp.) **Reviewed Date:** April 25, 2023 **What do you like best about Knock?** The workflow engine is a fantastic offering powering some truly flexible and extensible flows for our notification types through notification provider integrations and functions such as batching. Beyond the excellent product, the team is truly what I like most about Knock as they've been immeasurably helpful both during the onboarding process and beyond. The responsiveness and openness of the team has instilled a unparalleled confidence in the product as I know any issues that may arise will be resolved promptly and effectively. **What do you dislike about Knock?** There's nothing I can say I dislike about Knock as both the product and team have not only met but exceeded all expectations. I only wish they had an OpenAPI definition publicly available so I could help improve and extend their .NET client. **What problems is Knock solving and how is that benefiting you?** Knock handles the complexities and nuances of notifications within our platform and solves an immense problem of notification fatigue through their batch function, enabling us to ensure users are receiving important notifications without being overwhelmed at the same time. The UI/UX of building out notification flows prompts contribution throughout both the development and design teams as we can contribute to new and existing notifications, only requiring engineering to setup the foundations. The inline user identification solution makes integration a breeze as syncing users between the two systems isn't necessary, instead we're able to provide the necessary data at time of dispatch. ### 9. Easy notification platform that takes minutes to integrate **Rating:** 5.0/5.0 stars **Reviewed by:** Tim R. | CTO, Small-Business (50 or fewer emp.) **Reviewed Date:** April 25, 2023 **What do you like best about Knock?** Knock is developer-oriented and is incredibly easy to implement. Love the fact that we can setup multiple environments to mimic our application environments and test the notifications. Knock is exactly what we were looking for in a notification platform. **What do you dislike about Knock?** It seems like it's a bit early in the product cycle, and I am looking forward to new features in the future. I would love to see more capabilities around managing properties. It was pretty confusing at first trying to figure out how to go to production but we eventually figured out you had to "commit" your changes first to be able to deploy to the next stage. **What problems is Knock solving and how is that benefiting you?** We needed a notification platform that was quick to implement but would also have the features we needed for the future including sms and in-app notifications. Knock perfectly fits the needs and we're looking forward to expanding our existing use case as we continue to develop new features in our application. ### 10. Overall an easy product to work with **Rating:** 5.0/5.0 stars **Reviewed by:** Chloe T. | Mid-Market (51-1000 emp.) **Reviewed Date:** April 24, 2023 **What do you like best about Knock?** I love how you can clone workflows and steps in workflows. Easy UI to work with. I like how you can add conditions to the steps. I like how I push from dev to production environment. I like how I can go back and look at messages sent to users and what data was sent with the email. **What do you dislike about Knock?** If I don't have preview data for an email template it doesn't display anything on the preview. I usually rely on sending a test email because the preview tab doesn't always seem correct. When working with adding bullets and a paragraph after, the white space is finicky. I have tried to create variables to use for text after bullets but it always seems to tab to where the bullets are. Would love to have details be able to be saved on preferences. **What problems is Knock solving and how is that benefiting you?** Can send out different emails but use the same workflow. Allows Vercel to make pretty emails without doing it ourselves. We don't have to send emails ourselves. We can just trigger them based on data. ### 11. Customized notification flows made easy **Rating:** 4.5/5.0 stars **Reviewed by:** Matyas H. | Small-Business (50 or fewer emp.) **Reviewed Date:** November 15, 2023 **What do you like best about Knock?** It helped us to implement personalized notifications and notification-settings via various channels in just a few days. **What do you dislike about Knock?** Its not 100% self explaining but as soon as you got into the most important concepts its ok.👌🏻 **What problems is Knock solving and how is that benefiting you?** We got a out of the boy notification system without writing amy code. ### 12. A quick and easy way to get in touch with your customers with complex workflows **Rating:** 4.5/5.0 stars **Reviewed by:** Luis J. | Small-Business (50 or fewer emp.) **Reviewed Date:** April 24, 2023 **What do you like best about Knock?** Knock has provided us with a quick and easy path to engage with our customers meaningfully, without requiring extensive development efforts. With the Knock platform, we can easily set up new notifications and trigger them based on our data and existing service patterns. As we continue to scale our business, having a partner company like Knock has been incredibly valuable. Their platform has enabled us to keep pace with our growth and meet our customers’ needs in real-time. We’re grateful to have a partner that not only understands our business but is also invested in our success. **What do you dislike about Knock?** It would be helpful to have a React-Native library for the in-app notification feed, which is not available at the time of writing this review. **What problems is Knock solving and how is that benefiting you?** Contacting our increasing network of customers and partners through their preferred means of communication, while including some business logic into these kinds of communications. ### 13. Makes getting notifications set up easier **Rating:** 3.5/5.0 stars **Reviewed by:** Verified User in Computer Software | Small-Business (50 or fewer emp.) **Reviewed Date:** February 26, 2024 **What do you like best about Knock?** Saves me precious engineering time to build and maintain a notifications system **What do you dislike about Knock?** It's expensive. The documentation could be better. Was difficult to understand the API. Some things I would expect to be in the UI are not there **What problems is Knock solving and how is that benefiting you?** I don't want to build a notifications system from scratch. I've done this a few times and it's a pain. I also don't want to maintain one. ### 14. It has been one of the best services we’ve employed, easy to use and incredibly powerful. **Rating:** 4.5/5.0 stars **Reviewed by:** Andy N. | Small-Business (50 or fewer emp.) **Reviewed Date:** June 19, 2023 **What do you like best about Knock?** It's incredibly strait-forward; we've been able to carefully design and deploy our business needs while not having to spend too much time and resources setting up the platform. Another source of value for us was integration with other services, such as SendGrid, with ease, and the multi-platform support was no issue. **What do you dislike about Knock?** We think the templating experience was good, yet it was some improvements that can be added. Writing HTML was not straightforward. We instead wrote our HTML templates elsewhere than just copying and pasting. **What problems is Knock solving and how is that benefiting you?** Having a single place to manage user communication through email and push notifications, as developers, our productivity definitely increased, while been easy to understand for the business development team. ### 15. Pretty good but room for improvement **Rating:** 3.5/5.0 stars **Reviewed by:** Charles F. | Software Engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** August 03, 2023 **What do you like best about Knock?** Super simple to set up. Non technical people can drop in and make copy updates without bothering me, Mr Developer. The drop in widgets intergrated seamlessly into our stack. **What do you dislike about Knock?** There's a serious lack of conditional logic available. Comparing to our old provider, CustomerIO, we had a much more granular control about who got what message/notifications when. We miss that feature. **What problems is Knock solving and how is that benefiting you?** Simply providing push notifications to our users at the appropriate time. Not having to manage this infrastructure is incredibly helpful as we can focus on doing what we do best. ### 16. Notification infrastructure is easy with Knock **Rating:** 4.5/5.0 stars **Reviewed by:** Ali R. | Small-Business (50 or fewer emp.) **Reviewed Date:** April 24, 2023 **What do you like best about Knock?** Knock is great! It helps save so much time and effort for us. After the initial setup, defining workflows and setting up new notifications is straightforward. I love the ability for anyone to get into the product and see visually how each workflow is set up. **What do you dislike about Knock?** Nothing in particular. It is made for developers and does a great job at being that. **What problems is Knock solving and how is that benefiting you?** Knock primarily helps us batch notifications together before sending them to our customers. Notifying users about similar things could be annoying. Hence, the ability to batch and send updates once in a while vs. sending updates all the time is a much better experience for our customers. Thus, our notifications (primarily emails) for some use cases are more helpful and engaging. ### 17. Saved us a bunch of time and money **Rating:** 5.0/5.0 stars **Reviewed by:** Brendon P. | Software Architect, Small-Business (50 or fewer emp.) **Reviewed Date:** April 24, 2023 **What do you like best about Knock?** Like authentication, notifications are part of a system that users expect to be there and work but don't provide a ton of strategic value to a product. I dreaded building out a notification subsystem for our application. I knew it had the potential of becoming just as significant, if not larger, than the rest of our product. Knock was super simple to integrate, implement, and handle all of our use cases, plus some! **What do you dislike about Knock?** I don't have anything negative to say about Knock. Knock has built out more API surface and use cases than I even have a need for. **What problems is Knock solving and how is that benefiting you?** Knock solves our in-app notifications for when our background processes error out and require user interactions. ### 18. Knock got us to market quicker, continues to improve **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Computer Software | Small-Business (50 or fewer emp.) **Reviewed Date:** April 27, 2023 **What do you like best about Knock?** The core selling point of Knock is that it helps you get to market quicker. In most codebases, you'll have the dispensation to send notifications. Setting up code and infrastructure to support most notification use cases is not complex. But Knock does it better and helps you roll it out faster; these effects are even more profound if you need to launch with nontrivial notification features. Also, their support is great! **What do you dislike about Knock?** You'll have to think about notifications differently in your code (e.g., you are no longer asserting on rendered email content but on an API call). You no longer own notifications as a core concept, and that tradeoff might not be appropriate for your product. You are reliant on an intermediate party for contacting your users. **What problems is Knock solving and how is that benefiting you?** Knock powers our notification system (primarily email), which is a core part of our product. It allowed us to ship advanced notification features more quickly and let us focus on our core product rather than building notification features. ### 19. Easy to set up, built for security and to prevent accidents in production **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Human Resources | Small-Business (50 or fewer emp.) **Reviewed Date:** April 25, 2023 **What do you like best about Knock?** Using Knock's separated development and production envionments allows you to thoroughly QA and test without having to hack together a solution yourself. The workflow is set up naturally to what a developer would expect; making changes in dev, testing, and committing to the production environment. It reduces risk without having to spend time setting up. **What do you dislike about Knock?** There have been times when the documentation could have been better. However, I contacted support directly, and they solved my issue and consequently updated the documentation. **What problems is Knock solving and how is that benefiting you?** As a startup finding product market fit, we don't have time to build everything we need. Knock allowed us to integrate a highly customisable, stable notification service very quickly. We use Knock to send notifications to individuals and teams, but batch the notifications in different ways depending on the action/how many actions were performed. We also send email notifications if an in app notification wasn't seen in a certain amount of time. This is basically just the standard knock notification flow modified from one of the templates. ### 20. Powerful solution for Notification patterns of all complexity levels **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer Software | Enterprise (> 1000 emp.) **Reviewed Date:** April 25, 2023 **What do you like best about Knock?** As a software engineer on a Growth team, what I appreciate most about Knock is the platform's advanced capabilities, such as the scheduling feature and the Fetch functionality. The ability to schedule notifications ensures that our end-users receive timely and relevant updates, while the Fetch function allows us to execute HTTP requests within a workflow, acquiring additional data for our channel step templates. The Fetch functionality is particularly powerful as it enables us to retrieve data that may not be immediately available when a workflow is triggered. This feature is especially useful when combined with a batch function to gather trigger data for a group of activities after a batch window has closed. Additionally, the Fetch function can be used to trigger side effects in our systems as Knock processes the workflow. These advanced features, combined with Knock's API and user-friendly dashboard, simplify the process of designing, controlling, and delivering notifications. This saves our team time and effort while enhancing the overall user experience. **What do you dislike about Knock?** Though Knock excels in many aspects, one area that could benefit from further development is the integration of more comprehensive analytics. Providing deeper insights into user interactions with notifications, as well as real-time performance metrics, would help optimize notification strategies and improve the overall impact of our campaigns. Overall, Knock's advanced features, such as the scheduling functionality and the Fetch function, make it an invaluable tool for any Growth Engineering team. The platform's efficiency in managing product notifications, its user-friendly dashboard, and its powerful capabilities help businesses engage and retain customers effectively, making Knock an essential component of our notification infrastructure. **What problems is Knock solving and how is that benefiting you?** Knock is solving several critical problems related to product notifications, which in turn, greatly benefits our team and overall user experience. Some of the key problems Knock addresses include: 1. Complexity in notification management: Knock simplifies the process of designing, controlling, and delivering notifications through its API and user-friendly dashboard. This streamlined approach enables our team to focus on core product features while ensuring a seamless notification experience for our users. 2. Timely and relevant notifications: With features like scheduling and the Fetch functionality, Knock allows us to deliver notifications at the right time and with the most relevant information. This not only enhances user engagement but also drives customer satisfaction and retention. 3. Scalability and flexibility: Knock's platform is built to handle high volumes of notifications while remaining adaptable to the changing needs of our product and user base. This scalability ensures that our notification infrastructure can grow and evolve alongside our business. 4. Reducing technical debt: Knock eliminates the need for our team to build and maintain an in-house notifications system, reducing the risk of technical debt that can hinder our organization's growth and productivity. 5. Empowering non-technical team members: The Knock dashboard allows product and growth teams to create and update notifications independently, without the need for constant engineering support. This autonomy speeds up the decision-making process and improves the overall efficiency of our team. By addressing these challenges, Knock significantly benefits our team and business by streamlining the management of product notifications, enhancing user engagement and retention, and reducing the burden on our engineering team. This allows us to focus on improving our core product offerings while maintaining an exceptional notification experience for our users. ### 21. Everything you need for any type of notification, with minimal setup. **Rating:** 5.0/5.0 stars **Reviewed by:** Andrew G. | Co-Founder & Engineering Lead, Small-Business (50 or fewer emp.) **Reviewed Date:** April 24, 2023 **What do you like best about Knock?** Insanely easy to setup. Very easy to setup multi-channel notification flows, with no / minimal code. Many supported client libraries. Great documentation. Great support. **What do you dislike about Knock?** We've been using knock for over a year, and there isn't anything I dislike about it. Anytime I've hit a bug or issue, the team has resolved it promptly. **What problems is Knock solving and how is that benefiting you?** Knock allows us to keep our notification code simple in our various applications. We simply report basic user information to Knock, and then trigger workflows. All our workflow logic, and templating is in Knock, and our app code doesn't need to change. Changes to our notification wording, logic, or delivery now takes seconds, with no need to redeploy our application. ### 22. Easy to use and easy to follow **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Internet | Mid-Market (51-1000 emp.) **Reviewed Date:** April 24, 2023 **What do you like best about Knock?** We've evaluated other notification systems along with Knock. Areas they excelled at (compared to their competitors) were documentation and SDK; they were up-to-date and easy to follow. The people at Knock have also been helpful with their fast response to requests and concerns we've raised. **What do you dislike about Knock?** Knock is still a newcomer (or is one of them) in this field compared to its competitors. This made it a bit harder to convince our leadership about Knock. There were also very few infrastructure blips due to the volume of notifications we've been sending. But they were able to recover within hours, were transparent about the root cause, and outlined their plan for improvements. **What problems is Knock solving and how is that benefiting you?** Improving our notification system has been an ongoing discussion internally within our company (i.e. centralizing different notification channels into one system). One of the major concerns was the velocity of how we can deliver the improved notification system (if we were to build it ourselves). Knock has not only saved us time to build a notification system, but also saved us money that would have been used to hire more resources. ### 23. Great all-in-one platform with a few bugs **Rating:** 4.0/5.0 stars **Reviewed by:** Mona F. | Small-Business (50 or fewer emp.) **Reviewed Date:** April 24, 2023 **What do you like best about Knock?** Our development team needed to build a notification system that worked in our web platform (React Native + NextJS) and to our Mailgun + Twilio systems. We needed to notify our sellers and buyers of their orders. Knock was able to get us to do that reliably. They were able to integrate with Segment -- which we needed in order to have all of our data movement centralized in one point. **What do you dislike about Knock?** There was a few bugs. Data wasn't sent in the right places. In-app notifications didn't get pushed right. Thankfully, whenever I pushed the bugs, the customer support team ACTUALLY fixed my problems. This was great. Especially for a product that is so hybrid with SaaS and DevTool, it was very helpful to get direct product support when something was wrong. They were even willing to check my code -- to see if it was my implementation error or theirs. **What problems is Knock solving and how is that benefiting you?** Creating transaction notifications in one centralized location without having to hard code it into our system. This makes it flexible. What's great is the app logs the event notifications. This gives me security in knowing our sellers and buyers are ACTUALLY receiving the notification. ### 24. Knock has drastically improved our DevUX for building notifications **Rating:** 5.0/5.0 stars **Reviewed by:** Zach W. | Small-Business (50 or fewer emp.) **Reviewed Date:** April 24, 2023 **What do you like best about Knock?** They've built an intuitive flow to develop, test and ship notifications for all channels. I love the support for testing in a sandbox, handling complex logic based on user attributes and managing multiple channels for the same notification on one spot. **What do you dislike about Knock?** Notification templates are hard, still lots of room for improvement around template components and making it easier to style. I'd love to move the templates in code to make it even easier for my developers. **What problems is Knock solving and how is that benefiting you?** Managing notification channels for email and sms in one location where we can develop, test and ship it all. Template management, integrations with third parties and testing notifications are a pain and Knock makes it easy. ### 25. Great DX and very responsive **Rating:** 5.0/5.0 stars **Reviewed by:** Matt M. | Small-Business (50 or fewer emp.) **Reviewed Date:** April 25, 2023 **What do you like best about Knock?** Rapid implementation of new features and very quick customer support via the slack channel. I've been able to meet with the cofounders to discuss my specific use case and how I could use Knock (and what new features they were building) to implement notifications infrastructure in my product. **What do you dislike about Knock?** I just haven't gotten completely comfortable with the multi environment set up. I understand how it works, but I think I just need to play around with it a little more to get comfortable with it. **What problems is Knock solving and how is that benefiting you?** It's saving me the headache of having to build out an entire notifications infrastructure for my project. It's saving me a ton of engineering time. ### 26. Knock is notifications and convenience done right **Rating:** 5.0/5.0 stars **Reviewed by:** Grant W. | Small-Business (50 or fewer emp.) **Reviewed Date:** April 24, 2023 **What do you like best about Knock?** We love how simple it is to integrate and how responsive the team is to anything that has come up. The template builder allows for great-looking emails and saves us time with complex features such as delays, batching, etc. Highly recommend. **What do you dislike about Knock?** It's still early in their journey. However, they power all of Vercels notifications, so it's hard to say anything that needs immediate improvement. Perhaps templates and recommendations would be helpful. **What problems is Knock solving and how is that benefiting you?** We are using Knock to replace the time it would take to set up a robust notification and transactional email service on our end especially taking into consideration logs and debugging. ### 27. Great experience **Rating:** 5.0/5.0 stars **Reviewed by:** Runs L. | CEO, Small-Business (50 or fewer emp.) **Reviewed Date:** November 15, 2023 **What do you like best about Knock?** Great analytics, easy to set up, no fuss **What do you dislike about Knock?** The price is higher than competitors' offerings **What problems is Knock solving and how is that benefiting you?** We use Knock for in-app notifications and email notifications for when a video is completed ### 28. Developer focused and delightful to use **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer Software | Small-Business (50 or fewer emp.) **Reviewed Date:** April 26, 2023 **What do you like best about Knock?** Knock is super simple to setup, while supporting our complicated workflow setups. Their secret power is a pleasant UI interface AND great developer SDKs. Both product and engineering loves using Knock. **What do you dislike about Knock?** Ony wish I used them sooner! Would've saved us the trouble of gluing multiple notification providers by hand. Their new CLI tool empowers us to control our notifications config via code instead of editing the config in the UI, so we're happy to move in this direction. **What problems is Knock solving and how is that benefiting you?** We focus on our product, letting Knock excel on the notification management and delivery problem. Their dashboards and logs allow any team member to quickly jump in to debug issues or customize things, instead of relying on disparate dev logs or using one-off internal tools. ### 29. Beyond Impressed - There is soo much to the product and the people behind it. **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Education Management | Small-Business (50 or fewer emp.) **Reviewed Date:** April 24, 2023 **What do you like best about Knock?** I like that it is well thought out before development. Reading their documentation and integrating their product into your product is like a story well written. Alot of aha moments and everything makes sense. **What do you dislike about Knock?** So far, nothing. I was skeptical as to their pricing in the beginning. But per the value they provide to you in return, it is beyond well worth it! **What problems is Knock solving and how is that benefiting you?** We use Knock for what I would term our collaborative network. Because with one api/service, you can notify your users in many places, it makes incredible sense, that we use it to get our users to know about things where they are. - In addition to that more advance, very basic problems like Authentication notifications etc are also fully solved for. ### 30. Resolving daily notifications emails on the fly! **Rating:** 5.0/5.0 stars **Reviewed by:** Nicolás S. | Small-Business (50 or fewer emp.) **Reviewed Date:** April 24, 2023 **What do you like best about Knock?** - Easy integration using their SDK - Super easy UI for tracking your emails and generating complex workflows - Integration with Sendgrid - Multiple environments - Team support **What do you dislike about Knock?** - Templates for emails can be a challenge, but once you get used to them, they are great, especially with the internalization feature that they add. - Limit the quota of notification emails. **What problems is Knock solving and how is that benefiting you?** Daily notifications and push notifications related to various user actions are determined by multiple parameters (such as user role and feature flags) configured through their template/workflow engine. ### 31. Great tool to create journeys & manage notification channels **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Leisure, Travel & Tourism | Mid-Market (51-1000 emp.) **Reviewed Date:** May 07, 2023 **What do you like best about Knock?** Very easy to manage new/edit notifications, adding more notifications or adding new channels is very straight forward. Knock team is very receptive about potential new features and suggestions. I love the commit methodology they implemented to have the changes imacted on staging + production environments. **What do you dislike about Knock?** It's not very practical to send notifications in several languages. If you have several branches, you will have to duplicate your workflows. When you start getting several whitelabel branches this can get annoying **What problems is Knock solving and how is that benefiting you?** Knock is solving the journey logic and the edition of templates in an easy way in order not to depend on the technical team for these type of small changes on the notifications. ### 32. Knock is great to offload most of our communication concerns! **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Leisure, Travel & Tourism | Small-Business (50 or fewer emp.) **Reviewed Date:** April 27, 2023 **What do you like best about Knock?** It's super easy to implement new push, sms and email communications, the templating system makes it so we're very fast at deploying new workflows. The configuration options for workflows are unmatched, allowing us to schedule, add delays based on payload, and even make API calls in the middle of a workflow to dynamically change behavior. **What do you dislike about Knock?** Not having an extra way to group workflows, currently we can group by category, but it would be nice to have a folder of sorts. **What problems is Knock solving and how is that benefiting you?** We've offloaded all our communication integrations to Knock. It's much easier to add and configure new flows just by going to the dashboard. There's no need for engineering work to iterate or change communication flows. ### 33. Great value, reliable notifications infrastructure that is easy to integrate and operate **Rating:** 4.5/5.0 stars **Reviewed by:** Jonathon B. | Small-Business (50 or fewer emp.) **Reviewed Date:** April 25, 2023 **What do you like best about Knock?** The documentation is generally great, easy to adopt (APIs, attractive defaults), and reliable in the six months we've been using it. The free tier is generous, and the staff are quickly responsive in the Slack workspace. **What do you dislike about Knock?** Although the web user interface is good, sometimes I want to be using an API to control changes. Knock's team has said that this functionality is coming soon, but we'll see. **What problems is Knock solving and how is that benefiting you?** We started with Amazon SES and ugly HTML email content built using string concatenation. Our immediate need was to improve our email HTML build system and add some basic notification batching. Knock had nice support for layering over AWS SES, which made my integration work a lot easier. ### 34. Knock is my favorite dev tool in our stack **Rating:** 5.0/5.0 stars **Reviewed by:** Jay A. | Small-Business (50 or fewer emp.) **Reviewed Date:** April 27, 2023 **What do you like best about Knock?** I love the completeness of the knock feature set, the reliability of the product, and the responsiveness of the team. **What do you dislike about Knock?** I don't have any complaints about knock. I have yet to run into a product limitation or issue with the team. **What problems is Knock solving and how is that benefiting you?** We run a high-volume sales process where responsiveness of our team is key. Knock helps us integrate and change notification flows across a variety of tools and platforms with low overhead. ### 35. Manage your notifications seamlessly **Rating:** 5.0/5.0 stars **Reviewed by:** Emilien P. | Small-Business (50 or fewer emp.) **Reviewed Date:** April 26, 2023 **What do you like best about Knock?** All the integrations they have makes us capable of adding another target for our notifications in a blink of an eye **What do you dislike about Knock?** I wouldn't say I dislike anything, but I think we've reached the limit of their Slack integration and had to handle things on our side for this. **What problems is Knock solving and how is that benefiting you?** Knock is helping us gather all our notifications in one place. They're so flexible that adding or changing anything is fast and reliable. ### 36. Easiest Way to Get Notifications in your App **Rating:** 5.0/5.0 stars **Reviewed by:** Francisco D. | Small-Business (50 or fewer emp.) **Reviewed Date:** April 24, 2023 **What do you like best about Knock?** There's a generous free tier that allows you to add in notifications and testing it for your existing customer base while not paying a large fee **What do you dislike about Knock?** The UI has a few bugs here and there but the team is quick to respond and resolve via Slack **What problems is Knock solving and how is that benefiting you?** Knock allows us to have multi-channel notification system without building it all ourselves ### 37. Knock made it easy to roll out notifications. **Rating:** 4.5/5.0 stars **Reviewed by:** Ethan Gabriel N. | Small-Business (50 or fewer emp.) **Reviewed Date:** April 28, 2023 **What do you like best about Knock?** Knock's structured workflows make it really easy to organize and keep track of notifications in our app. They also offer many different delivery channels. **What do you dislike about Knock?** Although understandable, I think Knock is a bit expensive. **What problems is Knock solving and how is that benefiting you?** Delivering notifications to our customers through various different channels. ### 38. Knock makes sending notifications easy and enables non-technical stakeholders to write the templates **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer Software | Mid-Market (51-1000 emp.) **Reviewed Date:** May 04, 2023 **What do you like best about Knock?** They handle notification delivery to multiple sources and enable non-technical stakeholders to own notification copy. Their support is excellent. **What do you dislike about Knock?** Observability is OK but could be better. Their logs UI work but there's no querying interface to better understand what notifications are being sent. **What problems is Knock solving and how is that benefiting you?** We use Knock to send transactional emails for our product as well as timely usage consumption notifications, and to enable non-technical stakeholders to own copy. ### 39. Knock G2 Review **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Small-Business (50 or fewer emp.) **Reviewed Date:** April 24, 2023 **What do you like best about Knock?** Its design and documentation are splendid, making implementation a breeze. Very intuitive to use in general. **What do you dislike about Knock?** It doesn't connect with our code repository, so template formatting code can only exist in the Knock environment. **What problems is Knock solving and how is that benefiting you?** Notify users about state changes in their workspaces through various channels, to make users feel informed, and add a mechanism to engage users by linking back to our product. ### 40.

They're always willing to thoroughly answer our questions, and they're responsive and receptive to feedback and improvement suggestions.

We also use it to email notifications to our internal team about the status of our products. It's been very useful so far. ### 41.
