About Customer.io
Unlike traditional email marketing tools, Customer.io is built around events. When a user performs an action in your app, it triggers a workflow that can send a series of targeted messages. It is highly technical and provides deep control over data and segments. Product and growth teams use it to build sophisticated onboarding sequences, re-engagement campaigns, and transactional notifications that feel deeply personal to each user's journey.
