# FutureMail > Email hosting for your domains and your AI agents: unlimited addresses, a fast keyboard-first inbox, and an API, CLI and MCP server (Resend-compatible). Free to start. FutureMail (https://futuremail.dev) is email hosting for people who own domains and for their AI agents. Buy a domain. Get email. That's it. Users get unlimited addresses and aliases on any domain, a fast keyboard-first web inbox, and the same capabilities over a REST API (https://api.futuremail.dev), a remote MCP server (https://api.futuremail.dev/mcp) and a Resend-compatible API (https://api.futuremail.dev/resend). Agent inboxes give each AI agent its own mailbox, address and scoped API key, and `wait_for_email` extracts one-time codes and links automatically. ## Docs - [Developer docs](https://futuremail.dev/developers.md): quickstart, authentication, sending, agent inboxes, MCP, Resend compatibility, webhooks, domains, endpoint reference, limits - [Full context](https://futuremail.dev/llms-full.txt): product overview, features, pricing, FAQ and the complete developer docs in one file ## Product - [Home](https://futuremail.dev/): overview and features - [Pricing](https://futuremail.dev/#pricing): Free $0/month (Addresses on futuremail.dev; Agent inboxes, API, CLI & MCP; 3,000 recipients a month (100 a day)).
