4.5/5

Customer.io excels in managing complex behavior-driven campaigns across various audience segments, particularly with its integration of Claude MCP and support for SMS and WhatsApp workflows. However, the user interface can be unreliable, often feeling laggy or glitchy during navigation and editing.

Powerful Abandoned-Checkout Automation, with a Learning Curve

I like how simple it is to send events and user attributes through Customer.io. I also like the API and the exceptionally user-friendly email template builder.
