The segmentation and attribute features are very helpful and they can accommodate everything we need to store the details. Review collected by and hosted on G2.com. What do you dislike about Customer.io? They do not have an in-build web push notification feature. We have to use a 3rd party vendor and use their webhook to push these notifications. Review collected by and hosted on G2.com. What problems is Customer.io solving and how is that benefiting you? We are able to capture the entire user journey on customer.io. Right from when a user signs up to all of the different segments they go through, customer.io is able to capture all the details and then help us segment the outreach. This has helped us reach the user at the right nudges. Review collected by and hosted on G2.com.

I like how Customer.io pairs with Salesforce to execute email campaigns over extended periods and neatly tracks data. The great AI assistant makes it easy to use. I find it easy to visually see and understand campaigns, which is really helpful. I also appreciate the ability to make segments of customer profiles. The setup was easy, and I'm getting the hang of it with good use. Review collected by and hosted on G2.com. What do you dislike about Customer.io? On the campaigns, I would like to scroll with my mouse by clicking and moving on the screen. Now I need to zoom in and out and have to move sliding toggles on the right and bottom. Also, I'd prefer a more digital-friendly way of making emails, similar to Canva, where you can move, drag, and drop features rather than needing fancy code or graphic design experience. Review collected by and hosted on G2.com. What problems is Customer.io solving and how is that benefiting you? I use Customer.io to integrate with Salesforce for running long-term email campaigns. It neatly tracks data and the AI assistant makes it easy for me, offering a visual interface. Customer segmentation is crucial for managing our varied groups and campaigns.
