Customer.io UI design & app screens

Customer.io is a marketing automation platform for sending behavior-triggered messages across email, push, SMS, and more. It serves marketing and growth teams building data-driven lifecycle campaigns.

The interface is a reference for automation and messaging UX: visual campaign and journey builders, segmentation based on event data, message composers, and performance analytics. Designers study its workflow canvas, branching logic, and the way it makes complex, data-driven messaging campaigns visual and manageable.
