RelayMail

Your email, your rules. No nonsense.

A friendly fork of Thunderbird for Android — same powerful email client, plus the stuff you always asked for. Privacy-focused, open source, and built for people who just want their email to work.

Install with Obtainium

Private by default

No tracking, no telemetry, no surprises.

Auto-updates

Always fresh via Obtainium. Set it and forget it.

Just email

IMAP, SMTP, push — the things that matter.

Open source

Read the code, fork it, make it yours.

New here? Here's the deal.

RelayMail installs through Obtainium — a free app that grabs updates straight from GitHub so you're always on the latest version. No app store middleman required.

  1. Grab Obtainium from your favorite source:
  2. Tap the big blue Install with Obtainium button above.
  3. That's it. Obtainium handles the rest. Go make some coffee.

Prefer the scenic route?

You can always download the APK yourself from GitHub Releases. No judgment — we respect a hands-on approach.

Standing on the shoulders of giants

RelayMail wouldn't exist without the incredible work of the Thunderbird team and the K-9 Mail / Thunderbird for Android community. Years of tireless development, thousands of commits, and a genuine love for open-source email — we're grateful for every line of code.

If you want to support the people who built the engine under the hood, consider donating to Thunderbird. They deserve it.
