mailbot

AI agents need email, but most teams hack SMTP relays and parse raw MIME. Threads break, replies disappear. mailbot gives your agent a real email identity: programmable inboxes, threaded send and receive, webhooks for every delivery event. One API. Built in: MCP Server (npx mailbot-mcp, works with Claude Desktop, Claude Code, Cursor), Node.js and Python SDKs, SPF/DKIM/DMARC deliverability. Free sandbox. No credit card.
