- Reach the right people with AI-assisted and manual segmentation plus custom objects
- Configure automations from a single prompt using the AI Agent

How It Works
Teams first connect their data through mobile SDKs, APIs, webhooks, or pre-built integrations so events and attributes flow into Customer.io in real time. Marketers then build journeys in the visual workflow builder, trigger them from segments, events, forms, dates, or webhooks, and launch from draft mode. Analytics dashboards and A/B tests help teams refine each send over time.
