## What Customer.io is

Customer.io is a platform for organisations that send automated messages using customer profile and event data. It supports communications across email, push notifications, in-app and web messages, SMS, Slack messages and webhooks.

Users group profiles into segments based on attributes or behaviours. They build workflows with triggers, goals and exit criteria, which send messages or perform actions as profiles meet defined conditions. Customer.io connects with other systems through REST APIs, mobile SDKs and data pipeline integrations.
