FounderMail is real email on a domain you already own on Cloudflare, without the setup. Your Cloudflare account carries the DNS and a thin Worker relay, and FounderMail runs the mailbox behind it. It is built for people and AI agents alike, with shared inboxes and agent seats on your own domain. It launched on Product Hunt on November 4, 2026.
What it does
Setting up email on your own domain usually means DNS records, DKIM, SPF and DMARC, and a mail host to maintain. FounderMail removes that work: connect your Cloudflare account, and it handles the mailbox while your domain stays yours. Personal and shared inboxes sit side by side in one unified inbox, with threads labelled by mailbox, so hello@, sales@ and support@ live next to your personal mail.
The agent angle is the point. FounderMail ships a REST API, OAuth and two MCP servers (mail and control plane), with agent seats that carry separate read and send scopes, so an AI agent can work your inbox without holding the keys to everything. One relay per Cloudflare account covers every domain on that account, and your data stays portable: you can export every mailbox as mbox.
