Pidgeon

Pidgeon is an email API that gives AI agents their own inboxes to send, receive and manage mail programmatically. Each agent gets a real email address on your domain, can read and reply to threads, handle attachments, schedule follow-ups, and manage calendar invitations all through code. The service integrates with Claude, Gemini, Grok and other agents via MCP servers, or you can call the REST API directly from TypeScript, Python or the CLI.

Every inbound message passes through Pidgeon's Firewall, which screens for hidden instructions and presents a clean copy to your agent. Mail and data stay in the EU on every plan, and nothing is used for training. You can set scoped API keys so each key only accesses what it needs, and all events are logged for 90 days.

Start free with three inboxes and 3,000 emails a month. The Developer plan costs €20 a month for ten inboxes and 10,000 emails. Add-ons like extra inboxes or domains cost €2 a month each, and sending beyond your plan's limit costs €2 per 1,000 emails. Receiving is always free.
