Why it matters

For founders running agents that need to send and receive email from a real domain without standing up mail infrastructure. Agents only get mailbox access a human grants, over MCP or REST.

Highlights

Point a Cloudflare-owned domain at FounderMail; DNS and a thin Worker stay in your Cloudflare account while the mailbox is hosted by FounderMail.
Founder plan $20/month (20 GB); Team $200/month (200 GB); unlimited people, agents, mailboxes, addresses and domains on both; 14-day Founder trial with no card.
Two Streamable-HTTP MCP servers on api.foundermail.app: one for mail (read/send/write scopes) and one for estate/control (org scopes); a token for one is refused by the other.
REST API at api.foundermail.app with OpenAPI; agents authenticate with a mailbox API key or OAuth grants issued by a human.
Inbound mail is treated as untrusted; messages can be flagged for injection but are still returned for the agent to read carefully.

Taken from the project's own README, docs or launch page. Claims about speed or accuracy are the maker's unless stated otherwise.

Try it if: Your agent needs a real @yourdomain address and you already keep DNS on Cloudflare.

Worth knowing: FounderMail does not build or host agents. Cloudflare account authorisation for installs is human-only. Mail body content can try to steer an agent; check injection flags before acting on inbound text.
