What do you like best about Slack?

Slack is so user friendly, its crazy that other platforms aren't as easy to use. It's up to date and in real time, and I love the "channels" function, as its easy to send a quick note to multiple people instead of an email which can get lost. It helps us get answers & info quickly and is super helpful. I also love the emoji's that make it easy to give someone's message a "thumbs up" instead ofpeople having to type individual messages of "understood" Review collected by and hosted on G2.com.

What do you dislike about Slack?

I liked how easy it used to be to "star" a conversation, now you have to do a couple of extra clicks and it can be cumersome and a little annoying.

Not the end of the world, but the way it used to be was much easier and I'm not sure what that changed. Review collected by and hosted on G2.com.

Recommendations to others considering Slack:

Slack is GREAT - you will not be disappointed! So easy & user friendly, anyone can learn it quickly. Review collected by and hosted on G2.com.

What problems is Slack solving and how is that benefiting you?

It saves SO many emails! It's just nice to send a note and know that people read it and acknowledged with a thumbs up, whereas with emails you always have to wonder if they saw it if they do not reply. Slack is just such a time saver and makes my job easier, daily. Review collected by and hosted on G2.com.

What do you like best about Slack?

The user inteface for slack is quite easy to use. It allows us to organize discussions by topics, projects etc allowing us real time work communication. We have slack integrated with Hubspot, so based on the setup trigger we are able to use send slack messages to open channel or a person directly which helps us to attend priority alerts. Review collected by and hosted on G2.com.

What do you dislike about Slack?

While using hubspot workflows we are not able to tag persons on the slack channels, which is a bummer for us & sometimes Ctrl+F does not respond very well. Review collected by and hosted on G2.com.

What problems is Slack solving and how is that benefiting you?

Slack is a comprehensive communication platform, which is super easy to use. We are able to send instant alerts from Hubspot to Slack Channel or to a user directly which helps us attend urgert queries very promptly. Further, slack integration also allows us to manager our hubspot live chat from slack itself, when a customer uses live chat on website, it get sent to a designated hubspot channel & we are able to carry on with the chat from slack itself, which is super nice.

What do you like best about Slack?

What I really like about Slack is how it keeps communication organized and easy. It's like having one big virtual office where you can chat with your team real-time, share files instantly, and integrate tools like Google Drive, Trello, and more. The channel system is great because it keeps conversations focused and easy to follow, whether it's for a project, department, or just casual team banter. Also, the ability to search through past messages is so helpful when you need to find important information quickly. Plus, the playful elements like emojis and GIFs add a bit of fun to work communication, making it more engaging and less formal. Slack really helps teams stay connected and productive, no matter where they're working from. Review collected by and hosted on G2.com.

What do you dislike about Slack?

In a rare situation, there are delays with how notifications come in, either due to poor internet signal or notification settings that can be set. Review collected by and hosted on G2.com.

What problems is Slack solving and how is that benefiting you?

It managed the communication well within the organization and integrated some of other systems we use at work as a one-stop tool for everyone. Sharing links, video, and audio conferencing is easy, and the fun part is that all members of the organization can join and hop into any events or special announcements. It has a to-do task listing and calendar management too. Review collected by and hosted on G2.com.

What do you like best about Slack?

Slack has transformed how our team works, keeping everyone connected, whether in the office or remote. Dedicated channels help keep conversations organized, and integrations with tools like Google Drive, Trello, and Zoom streamline our workflow. The search feature is a lifesaver for finding old messages or files, and features like huddles and Slackbot make collaboration faster and easier. It’s become an essential part of our daily routine. Review collected by and hosted on G2.com.

What do you dislike about Slack?

Slack is great for communication, but managing a flood of messages and channels can get overwhelming. Notifications can be distracting without customization, especially for cross-functional projects. File storage limits on the free plan can also be a challenge for growing teams. While integrations are helpful, setting up complex workflows can take time and technical know-how. Better notification controls and streamlined workflows would make Slack even more effective. Review collected by and hosted on G2.com.

What problems is Slack solving and how is that benefiting you?

Slack has solved many of our team’s challenges with fragmented communication and delayed updates. Its real-time messaging and channel-based organization keep everyone aligned, making it easy to track progress and stay accountable. Integrations with tools like Trello and Asana ensure tasks discussed in Slack flow seamlessly into our workflow. Features like file sharing, huddles, and video calls have improved collaboration and cut email usage significantly. Since adopting Slack, we resolve issues 30% faster and make decisions more efficiently—it’s become essential to how we work. Review collected by and hosted on G2.com.

What do you like best about Slack?

I like Slack because it allows me to communicate and collaborate with my team members easily. It is very easy to use and makes it easy to stay organized through the different channels and direct messages that I get. I like that the search feature is easy to use and it's super helpful in finding previous conversations. I use slack every single day and honestly it's my favorite platform to use to communicate with teammates on. Overall, Slack helps me stay connected to my teammates. Review collected by and hosted on G2.com.

What do you dislike about Slack?

The thing I dislike most about Slack is the large volume of notifications that I receive. It can be overwhelming at times, although I could probably adjust my settings to make that better for me. I also feel like the channels can get messy and sometimes it is hard to find past conversations because they will become buried in newer ones. Review collected by and hosted on G2.com.

What problems is Slack solving and how is that benefiting you?

Slack allows for seamless conversation between my entire company. It's also nice that it can be used for screen sharing, video conferencing and workflow management. Review collected by and hosted on G2.com.

What do you like best about Slack?

The best aspects of Slack are its intuitive communication channels, which enable organized collaboration within our teams. Features like thread discussions, file sharing, and integration with tools like Google Drive, Trello, and Zoom make workflows seamless. Slack's search functionality and customizable notifications ensure users stay on top of tasks without being overwhelmed. The platform’s flexibility for remote work and team coordination is a significant advantage, fostering efficient communication in both small and large organizations. Review collected by and hosted on G2.com.

What do you dislike about Slack?

What we dislike about Slack :

1. Cost for Larger Teams: Slack can become expensive as team size grows, especially for organizations requiring advanced features

2. Notification Overload: Without proper configuration, frequent messages across multiple channels can lead to distraction.

3. Learning Curve for New Users: First-time users may find it overwhelming due to its many features.

4. Limited File Storage: Free plans have restricted storage capacity for shared files.

5. Dependency on Internet: Slack's functionality heavily relies on a stable internet connection. Review collected by and hosted on G2.com.

What problems is Slack solving and how is that benefiting you?

Slack solves the problem of fragmented team communication by providing a centralized platform for messaging, file sharing, and collaboration. It helps streamline workflows by integrating with tools like Google Drive, Zoom, and Trello, making it easier to manage projects and keep everyone aligned. The benefits include improved productivity, reduced reliance on email, and enhanced transparency in team interactions, making it ideal for both in-office and remote work environments.

What do you like best about Slack?

Slack is a fantastic tool for keeping teams connected. The intuitive design makes it easy to organize communication into channels, ensuring everyone stays on the same page. I also love the integration options with other tools Review collected by and hosted on G2.com.

What do you dislike about Slack?

can become overwhelming with too many notifications, making it hard to focus on priorities. The pricing can be steep for smaller teams, and the file management system isn’t always user-friendly for finding previously shared documents Review collected by and hosted on G2.com.

What problems is Slack solving and how is that benefiting you?

Slack has been a game-changer for solving the challenge of keeping teams connected and organized, especially in a fast-paced environment. One of its biggest benefits is how it replaces endless email threads with real-time communication. It’s so much easier to hop into a channel and find exactly what I need without digging through my inbox.

It’s also been incredibly helpful for collaboration—integrating with tools like G-suite means I can share files or updates seamlessly without leaving the app. And the ability to have specific channels for projects or teams keeps everything focused and transparent, so no one feels out of the loop.

Honestly, Slack feels like the glue that holds everything together, making teamwork smoother and helping us all stay on the same page, even when we’re spread across different locations. It’s not just a tool—it’s become part of how we work. Review collected by and hosted on G2.com.

What do you like best about Slack?

I think that it's good for communication. I have been working with it for years. It's like Skype on steroids. I use Slack every day for my job with Open English. I have not had any reason to talk to customer support because it has been great. There are a lot of other features that I have used and so easy to use. If you want to transfer everything over the integration process is very easy. I never had any issues with Slack and the ease of implementation has always been 5 stars for me.

What do you dislike about Slack?

Sometimes, using Ctrl+F is not always functioning in a specific channel; I have to type in the #channel before the command is understood. Review collected by and hosted on G2.com.

What problems is Slack solving and how is that benefiting you?

Slack makes work so much easier by keeping all your team chats, files, and tools in one place, so you’re not juggling emails or switching between apps all the time. It helps you stay organized with channels for different projects, lets you quickly find past messages, and makes decisions faster with things like polls and reactions. Plus, it’s great for remote teams, with video calls and real-time chats to keep everyone connected. It’s secure, super easy to use, and just makes teamwork a lot less stressful and way more efficient. Review collected by and hosted on G2.com.
