Email infrastructure for AI agents — transactional sending, marketing campaigns, and lifecycle automation over a single contact graph. **Built so an agent can verify its own work.** Every "did that actually work?" question has a tool that answers honestly: render a template without sending it, read a delivery back from the log, replay a signed webhook against your endpoint, run a workflow and see each step it executed. **Tools document how they fail, not just what they accept.** A `200` does not mean delivered. A batch send returns `200` even when every message failed. `volanea_track_event` reports which workflows it actually triggered — an empty list means your event name has a typo, which is otherwise indistinguishable from a working integration. **Safe by default.** Test keys render and log but never deliver, even by accident. Campaigns are created as drafts — there is deliberately no tool that sends one. Cleanup previews unless you confirm, and only ever touches artifacts it cre
