About Customer.io
What is Customer.io?
Customer.io is a customer engagement platform that lets you trigger personalized messages—email, push notifications, SMS, and webhooks—based on real user behavior like sign-ups, cart abandonment, or milestones. It connects to your product data via API or SDK and uses a visual workflow builder to automate campaigns without coding.
Who is it for?
Built for product teams and growth marketers who need behavioral lifecycle campaigns (onboarding, re-engagement, upsell) without heavy developer dependency. Companies with complex user journeys requiring conditional logic and multi-channel messaging will benefit most. It may be overkill for simple newsletter-only broadcasts or very small lists under 500 profiles.
Real use cases
Common uses include: sending a welcome email sequence right after sign-up; triggering a push notification when a trial user hits a key feature milestone; or sending a personalized SMS offer when someone abandons a cart. The AI Agent (beta) can build and optimize campaigns from a simple prompt.
Key features
- Behavioral triggers — Send messages based on any user action or attribute change
- Visual workflow builder — Drag-and-drop conditional paths without coding
- Segmentation engine — Filter users by events, properties, or custom SQL
- A/B testing — Test subject lines, content, timing, and sender names
- Multi-channel — Email, push notifications, SMS, and webhooks from one interface
- Real-time analytics — See open rates, click rates, and conversion per workflow
