So, you’re hunting for an open-source email app for Android that keeps your privacy first? Smart move. With all the data breaches and tracking nonsense out there, you want an app that doesn’t treat your emails like a goldmine for advertisers. I’ve been there – sick of apps snooping on my inbox. That’s why I’m breaking down two of the best open-source email apps for Android that put privacy front and centre: FairEmail and Thunderbird for Android. Let’s dive in and figure out which one’s your vibe.
Why Open-Source Email Apps Matter in 2025
Let’s cut to the chase. Your email is personal – it’s for work stuff, family chats, and maybe even your bank details. But most email apps, like Gmail, track your every move to serve you ads or worse. Open-source email apps for Android are different. Their code is public, so anyone can check it for shady stuff. No hidden trackers, no secret data grabs. Plus, they’re built by communities who care about user freedom, not just profits. If you’re searching for privacy-focused email apps, these are your ticket to peace of mind.
Here’s a quick story: my friend Priya was fed up with Gmail’s constant ads. She switched to an open-source app, set up encryption, and now feels like she’s got her inbox back. That’s the kind of control we’re talking about.
FairEmail: The Privacy Powerhouse
FairEmail is an open-source email app for Android that’s all about keeping your data safe. It’s designed to be simple yet packed with features, focusing on what you need – reading and writing emails without the clutter.
Key Features
- Privacy First: FairEmail supports OpenPGP and S/MIME encryption, so your emails are locked tight. Its “Safe View” feature strips trackers from incoming emails, stopping companies from spying on what you read. It also warns you about unauthenticated messages and confirms images or links to block tracking.
- Customizable: Choose from six themes (blue/orange, yellow/purple, red/green, grey, black, or black and white) and tweak widgets to match your style.
- Easy to Use: Works with almost any email provider – Gmail, Outlook, Yahoo!, you name it. Setup is a breeze, even if you’re not a tech wizard.
- Pro Features: The app is free, but you can unlock extras like advanced search or email scheduling for a small fee (around $5-$10).
How to Get It
- Download from Google Play.
- Get it from F-Droid for a fully open-source experience.

Why I Like It
FairEmail feels like a breath of fresh air. It’s clean, fast, and doesn’t bombard you with ads or unnecessary features. The tracker-blocking is a game-changer – last week, it caught a sneaky pixel tracker in a marketing email I got. No thanks, spammer.
Thunderbird for Android: The Trusted Veteran
Thunderbird for Android, formerly K-9 Mail, is a heavyweight in the open-source email world. It’s been around since Android’s early days and is now backed by Mozilla, the folks behind Firefox. It’s reliable, privacy-focused, and perfect for managing multiple accounts.

- Proven Track Record: Built on K-9 Mail’s legacy, it’s battle-tested and trusted by millions.
