All my colleagues says that it has been very easy to learn how to use the tool. It is very intuitive and building an email and sending it out goes very smoothly. The drag and drop editor was very stable to use for creating our company branded templates.
Also very much appreciate the support we have received from customer.io and that you have the ability to really improve the product by having your say when it comes to feature requests. Review collected by and hosted on G2.com.
I am lacking functionality in building segments and working with conditions in campaign workflows. I think there are small improvements there that could give great benefits, in order to make it easier to set up the email journey the way we like.
I also think the documentation could be improved with some more examples to make it easier to understand how you can use all the great features of customer.io Review collected by and hosted on G2.com.

I really like the flexibility. We have around **350K** customers and a lot of campaigns **running**. The ability to spin up campaigns quickly has allowed us to move fast to address our needs. It's also incredibly powerful. The built-in features are great, but it's easy to connect to outside tools and scripting if needed. I **especially** like all the built-in A/B testing. The **administrative** visual reports allow me to quickly evaluate campaign/message effectiveness. Review collected by and hosted on G2.com.
I'd like to see some more powerful tools in the workflow builder. I'm not always able to branch in the ways that I'd like. Also, something as simple as assigning individual promo codes to a customer via messaging or a campaign often requires manual CSV importing or external scripting—I’d love to see a built-in feature for this.

Customer.io has been relatively easy for me to navigate and use on my own. I have experience with other platforms and not all are user friendly. Our account manager and the support team have also been extremely helpful along our jouney. Review collected by and hosted on G2.com.
Because our business is set up a bit differently than most there are some things that don't quite work for us. For example with the current set up, if I want to set the goal to be just having someone click an email I need to create a segment and set the goal to be for them to enter that segment. Another example is that some of our ongoing campaigns need to stop sending at a specific date, but currently we need to just make sure we go in on that day and manually stop them.

We absolutely love the formatting features for email marketing! It is so easy to fully customize the appearance of our emails, add our branding, photos, etc, and not have to worry about distortion when our patients get the email! We also love that customer.io easily integrates with our Prompt, our EMR software. Review collected by and hosted on G2.com.
The software itself isn't "pretty" when you're creating an email and segmenting lists of patients to send an email to. It can be a bit overwhelming to understand all the options, but when you spend some time with it, everything makes sense! Review collected by and hosted on G2.com.

Customer.io helps us to track every event, click, pageview happening in our platform automatically and create dynamic segments based on the activities of the people. And the best part, we can integrate it with our Backend so that we don't miss any events to adblockers. Normally this would take a dedicated person to track and analyze and act on those metrics, now we just set it up and forget it! Review collected by and hosted on G2.com.
I couldn't say I dislike, but a comprehensive product like this should have it's own event analytics features. We shouldn't have to send data to other analytics platforms, it's already there! Review collected by and hosted on G2.com.
As a company with over 2,400 employees, we value our customers and always want to improve the way we communicate and nurture our customer relationships. One focal point that made us choose Customer.io was its ability to remain simplistic while giving us the ability and tools to scale as we grow year-over-year. The search for the right platform for us wasn't easy; there were several calls with competitors that just didn't speak to our needs for multiple reasons, especially email platform usability, security, and infrastructure.
When we chose Customer.io, we were almost immediately able to increase our deliverability and solve several longstanding issues that increased our reach across all our stores. Even as we enter the new year, we're still discovering new ways we can increase our productivity, reduce our team's workload, and continue to scale our business. Customer.io truly puts the power back into multi-channel messaging to create a cohesive environment that our customers can feel engaged in. Two million customers strong!

I think Customer.io should show more support for their smaller customer base. Yes, we are a big company, but extending some of these great features to smaller customers would push the platform even further. Specifically, chat support and utilizing collections in workflows. Review collected by and hosted on G2.com.

I think customer.io has a clean UI and it's pretty intuitive. But the thing I think is the best is their customer support. We have an amazing rep who is knowledgeable, always available and supportive. Their chat support is also great - easy to get, rarely any wait times, and consistent and timely follow-up. Across the board, one of the best support teams I've worked with. Review collected by and hosted on G2.com.
There are always small things when it comes to functionality that you wish you had, but they are probably not as applicable to other businesses or do not fit into the core c.io business strategy so not on the roadmap for product development. There is nothing major. Review collected by and hosted on G2.com.

I've been using the tool for a year and half now, I use it daily and the platform seems to be more intuitive than ever. I've been able to pitch better use cases for the tool at my organization and implement them with remarkable results. The control I've had over the larger picture as well as granular details is quite useful. The tech support has been a savior and their feature rollouts have been easy to follow. Beyond everything, as a marketer, I think the company as a brand does amazing work - it applies B2C principles of communication seamlessly to an otherwise boring B2B category. It's been a pleasure.

I was disappointed when they changed their 'human' chat support to a bot - it is surely faster but it doesn't have the immediate option of someone being able to access my workspace remotely and helping me through something. The capabilities are endless so sometimes it is difficult to pick which new integration to dive into. Review collected by and hosted on G2.com.

I love using Customer.io! The campaign builder is incredibly useful and easy to use. I especially appreciate how intuitive it is to move blocks around and copy flows from one campaign to another. It makes creating and managing campaigns so much more efficient. Review collected by and hosted on G2.com.
There are a couple of things that could be improved. The email editor lacks an "undo" option, which can be really frustrating. If I accidentally delete something, there’s no way to recover it unless I exit the editor, which disrupts my workflow.
Another feature I miss is a way to check for overlaps between campaigns. When setting up a new campaign, it would be really helpful to see if some of its emails will collide with existing campaigns already running. Review collected by and hosted on G2.com.

I’m still using Customer.io at a moderate level, but I’m really happy with what I’ve seen so far.
The visual workflow builder makes it easy to set up emails based on product events, and there are plenty of customization options to personalize messaging.
I’ve also reached out to support a couple of times, and they’ve been super responsive and helpful. Review collected by and hosted on G2.com.
I don’t really have anything specific to dislike. The only issue I’ve run into is with the PostHog integration, but it’s still in beta. I haven’t reached out to the PostHog team yet, so I can’t say if it’s a real problem or just something on my end. Review collected by and hosted on G2.com.
