OpenMail

Email inboxes and messaging infrastructure for AI agents

Meet OpenMail

OpenMail provides email inboxes for AI agents and the applications that run them. Developers can create an address for each agent, send messages, receive replies, and keep conversations organized through an API, command-line tools, or supported agent integrations. Incoming mail can reach an application through webhooks or a WebSocket connection, avoiding a separate polling loop.

The service supports sender rules, multiple inboxes, attachment handling, and integrations with tools such as OpenClaw, Hermes, and Claude Code. An agent can use its inbox to receive verification messages, respond to support requests, or process documents sent by email. A free plan provides a starting point for testing an email workflow before expanding to additional inboxes and usage.
