What is AgentMail? Email inboxes made for AI agents: create inboxes by API, send and receive, threads, labels, drafts, attachments, webhooks and websockets. Priced by inboxes, emails and storage.

How an agent uses it: Each agent gets its own address and threaded mailbox; an MCP server works with Claude, ChatGPT and Cursor.

Best for: Agents that need their own inbox to receive, read and reply to email, not just send.
