FutureMail is email hosting for your own domain, built for people and their AI agents. It provides unlimited addresses, a fast web inbox, agent inboxes, and a REST API, CLI and MCP server that can do everything the inbox can.

How much does FutureMail cost?

Pro is $20/month and includes 50,000 recipients a month, unlimited custom domains and addresses, agent inboxes, the API and MCP server. Free plan for developers testing includes a sandbox domain with up to 10 recipients per rolling 24 hours (300 a month), no card required.

Can I send newsletters or marketing email?

No. FutureMail is for transactional and person-to-person email only: receipts, notifications, sign-in codes, replies, conversations. Bulk, marketing or unsolicited email and purchased lists are not allowed.

How do I give an AI agent its own email address?

Create an agent inbox in Settings → Agents, with POST /v1/agents, with `fm agents create`, or with the MCP tool create_agent_inbox. You get a mailbox, an address on your domain and an API key that can only touch that mailbox.

Is FutureMail compatible with Resend?

Yes. The same API is served in Resend's format under https://api.futuremail.dev/resend. Point the official Resend SDK at that base URL and use a FutureMail API key; emails, batch sends, scheduling, domains and API keys work unchanged.
