v1.0.0 · 6d ago
Self-hosted business email for unlimited users and domains, running as a Cloudflare Worker and D1 database in your own free account.
Why you might care
Gives small teams and solo developers shared mailboxes on their own domains without per-seat fees, with mail stored in your Cloudflare account. Receiving uses Cloudflare Email Routing, and sending falls back across Resend, Brevo, Mailjet, or SMTP when one provider hits its free limit. Still in beta, so test on a spare domain before relying on it.
