When we were on Mailchimp, we had severe deliverability issues for two reasons. The first being that we weren’t able to be on our own dedicated IP like we’re able to on Customer.io. Our emails weren’t going where they needed to go. The second was our inability to filter out users, and clean up lists within Mailchimp.
Anthony Aurrichio
senior Manager, Digital Engagement


Mailchimp was so difficult to integrate and required so much manual work. The implementation was so easy with Customer.io, the automatic setup and integration. With a click of a button, we were able to immediately start sending campaigns to our users. Plus they didn’t have the workflows Customer.io does.

We used Mailchimp before, but they didn’t really fulfill all of our needs. While browsing for a new platform, we spoke with several companies that had experience with Customer.io and all the feedback was super positive.
