Customer.io Reviews & Product Details

I love the 360 integration that Customer.io offers, allowing us to easily connect Segment, Mixpanel, and other tools with our marketing platform. I also appreciate the simplicity and power of the workflow builder in campaigns, making workflow creation accessible even to those without technical knowledge. The features allow the use of entry/exit triggers, delays, segments, and communication via emails, notifications, and webhooks, which is really powerful and very easy to use. Moreover, the initial setup was very simple and quick, which is a big plus. Review collected by and hosted on G2.com.

The React Native SDK has long been of inferior quality and complicated to customize. Tracking email and notification metrics has historically been complicated, and the SDK is really difficult to update, which is a real headache. Receiving feedback from developers and iterating on this basis, instead of focusing solely on the product, would be helpful. Review collected by and hosted on G2.com.

What I like most is how easy it is to set up and send targeted messages. It gives good control over who receives what, and you can create different flows without much confusion. I also like that it works well with data, so messages feel more personal instead of generic. The interface is clean and once you get used to it, managing campaigns becomes pretty smooth.

One thing I don’t like is that it can feel a bit complex in the beginning, especially if you’re new to it. Some features take time to understand properly. Also, pricing can feel a bit high for smaller teams, and sometimes small changes in campaigns are not as quick as expected. Review collected by and hosted on G2.com.

I find Customer.io super user-friendly and think it's a very robust platform. I love the AI chat box because it helps me identify issues, connect webhooks, and link reports to Google Sheets easily. The platform makes creating flows straightforward. It's easy to add conditions, messages, or time lapses. The initial setup was very straightforward, and it's enabled our business to make quick decisions and optimizations without heavy reliance on the development team.

The reporting aspects of Customer.io feel very basic to me. I would like the ability to create dashboards tailored for different user types, such as executive teams or operations teams. It's something that would be very helpful, but unfortunately, I cannot do that with the current setup. Another thing that I would like to enhance, is the fact that I cannot A/B test a transactional template. In our line of business, transactional emails are not just status order updates. We have a couple of cases where the user needs to take extra steps. It's important to have the capability to test different template to improve our CTR and conversions.

The data model. Everything is built around events and attributes so segmentation actually reflects what users are doing, not just the fields you filled in. The visual campaign builder is fast after you understand it, and Liquid templating gives real control over personalization without needing a developer for every change.

The built-in analytics are close to useless for real analysis. You have to pipe everything into an external platform just to answer basic questions about campaign performance.

Campaign-level exit criteria is limited to one condition. On complex journeys that gets restrictive fast.

The UI has small but constant friction points: no column sorting, no custom default views, things you'd expect from any mature SaaS tool.

The canvas is rigid. You can't move elements freely, which makes building and reading complex flows harder than it should be.

Event and attribute data has no visual layer. There's no quick way to sanity-check that data is flowing in correctly without digging into raw logs.

Testing a full journey is basically impossible. If you're building something with many branches and conditions, you need a way to walk a test user through the entire flow. That doesn't exist. Review collected by and hosted on G2.com.

I like that Customer.io makes it so easy and simple to create marketing emails across our dozens of clients. I love the integration with Twilio for SMS. But mostly, I love how responsive they are to questions, issue, concerns and feedback. The new AI integration has been great. I've spent the last few days training it on our workspaces and using it to assist with ideas for new projects and so far, I have been impressed. I cannot wait to integrate this new tool more into our email and sms workstreams. Review collected by and hosted on G2.com.

There really isn't much I dislike! I do think sometimes new features are rolled out without a ton of prior communication. And during testing or rollout of these new features, the platform can get slow or wonky. I think the huge features are communicated well. But for smaller things, it often creates issues, like when it only displayed emails up to 30 days for a week or two- a refinement that was not necessary and added more work.

Customer.io is a rapidly growing CRM, and in my opinion, the best approach is to implement features instantly based on customer needs. Review collected by and hosted on G2.com.

Overall, everything is good, but one thing they could improve is adding customer support by phone/call. Review collected by and hosted on G2.com.

I like seeing whether a message has been opened, clicked, or has bounced, and I also like that we're informed if an email has been suppressed or bounced. I find the broadcasts, flows, insights, dashboards, and person accounts features really helpful as they aid in reaching our audience and understanding the performance of our efforts. Additionally, the initial setup of Customer.io was very easy, which I appreciate. Review collected by and hosted on G2.com.

I'm experiencing an issue with Customer.io where many of my emails are being bounced or suppressed. This wasn't as much of a problem with my previous provider, so I'm not sure why it's happening more with Customer.io. Review collected by and hosted on G2.com.

I like how easy it is to build automated campaigns and manage different segments. The workflow builder is flexible, and having email, SMS and in-app messages in one place makes campaign management much easier Review collected by and hosted on G2.com.

Sometimes the workflow setup can feel a bit complicated, especially when creating more detailed automations. Review collected by and hosted on G2.com.

I really like how easy it is to navigate customer accounts and get the information I need quickly, the layout feels intuitive and user-friendly. Review collected by and hosted on G2.com.

The only downside is that the platform can be quite slow at times, and I occasionally run into lag, which makes handling multiple accounts a bit frustrating. If performance improves, it would be close to perfect for my workflow. Review collected by and hosted on G2.com.

I like Customer.io because it lets me send good looking emails without involving my developers too much in formatting. It allows me to customize emails easily with data, which is super helpful and saves time. The ability to import Excel files for sending emails is a feature I appreciate since I don't have to rely solely on an API. I also find the AI feature valuable as it assists me with any questions related to customizing emails. Overall, I find Customer.io to be great to work with. Review collected by and hosted on G2.com.

The timestamp features are a bit frustrating. I'm not sure why I have to use a Unix timestamp in my workflows. Otherwise, Customer.io has been great to work with. Review collected by and hosted on G2.com.
