Customers love us
Preferred by product-led companies


After evaluating Customer.io and Braze head to head, we decided to go with Customer.io for the ease of integration, transactional messages, our mobile capabilities especially push notifications, and for the support we know we would get.
Ivar Arulaid
Marketing Operations & Automation Manager


Customer.io can do what other marketing automation tools can’t—take in millions of events from users per day, segment through them almost instantly, and use any campaign action imaginable to create workflows.
Hamish Elmslie
COO


We use all channels in our campaigns, when it makes sense to do so. Last month we sent over 11M emails, over 5M push notifications, almost 1M in-app messages, and almost 100,000 SMS messages from Customer.io.
