What Customer.io is
What sets it apart Messaging is driven by real-time first-party behavioral events rather than static lists, and it now includes an AI agent that builds a full campaign (triggers, content, timing, logic) from one prompt and is callable via MCP, CLI, or API.
Built around behavioral data, Customer.io ingests first-party events and fires email, push, in-app, and SMS messages as users take actions, arranged in a visual journey builder. It differs from general email tools in how directly the messaging is driven by live product data, and it now ships an AI agent that turns a single prompt into a configured campaign with triggers, content, timing, and logic, callable through MCP, CLI, or API. Pricing starts at $100 per month on the Essentials tier for 5,000 profiles and a million monthly emails, then scales through Standard, Premium, and custom Enterprise plans, with a free year offered to early-stage companies that have raised under $10M. The fit is product-led and growth teams that need event-driven, multichannel messaging wired into their own data.
