What Is Customer.io?

Customer.io lets teams build automated messaging journeys from customer attributes and behavioral events. Its Journeys product supports email, push, SMS, and in-app messages with segmentation, branching, liquid-style personalization, and event-triggered workflows, while Data Pipelines can collect, transform, and route customer data between applications, warehouses, and messaging destinations.

Best for: Product-led and lifecycle marketing teams that need event-triggered customer messaging tied closely to product and behavioral data.

Customer.io Journeys is built around profile attributes and behavioral events sent from a product or data source. Those signals can trigger campaigns across email, push, in-app, SMS, WhatsApp, Slack, and webhooks, so product behavior can alter message timing and paths instead of relying only on marketer-managed lists.
