Web inbox Sign in
Received by Cloudflare, sent by your provider, kept on your server

Mail that lives at home.

Your domains, your server, no mail server to babysit. Accounts are handed out by whoever runs this server.

Sign in How mail arrives

Nothing listens at home.

Cloudflare takes the mail at the edge and a small worker hands it to this server. No open port, no mail server to patch.

  1. SenderAny mail serverMX sodi.email
  2. EdgeCloudflare Email Routingsodi-inbound worker
  3. Signed hand offThis serverapi.sodi.email/ingest
  4. Read anywhereWeb, desktop, Androidin.sodi.email

Server offline? The worker parks the message in R2 and this server collects it within a minute of coming back.

  • No port open at home

    The server sits behind a Cloudflare Tunnel. Every hand off is signed, and one older than five minutes is refused.

  • Offline is not lost

    Mail waits in a bucket while the server is down. Nothing is deleted until you delete it.

  • One interface, three clients

    The web inbox, the desktop app and the Android app speak the same API to the same server.

Keep the inbox. Lose the mail server.

Every message has a state

Queued, sent, delivered, or bounced with the reason. Outgoing mail retries until your provider takes it.

One panel for all of it

Domains, accounts, providers, credentials, the worker deploy, limits and the audit log. Admin sign in needs a second factor.

Private by default

Remote images stay blocked until you allow them, per message or per sender. No third party scripts.

Web, Windows, Linux, Android

Pick the server by domain or IP and sign in. Unread counts follow you.
