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.
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.
- Grab Obtainium from your favorite source:
- Tap the big blue Install with Obtainium button above.
- 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.
