AgentMail

About

Email built for agents, not for humans

AgentMail is a YC-backed email provider designed for autonomous agents: inboxes are created and operated entirely through the API. It supports threads and replies, attachments, realtime events, custom domains and semantic search, so agents can handle signups, OTP codes, support mail or outreach on their own. A hosted MCP server and a CLI make it easy to wire into Claude Code, Codex or Cursor.
