Review summary

Open-source Thunderbird-like Android client shines for multi-account users and desktop familiarity, but suffers from unreliable push, limited IMAP/folder management, weak spam controls, and setup/import hurdles.

Pros

Described as the best open-source email app for Android.
Handles multiple accounts smoothly and makes cross-provider management easy (e.g., Google, Outlook).
Gives a familiar Thunderbird desktop-like experience on Android, appreciated by long-time Thunderbird users.

Cons

Push notifications are unreliable or delayed (not real-time).
IMAP/folder management is limited (cannot create folders; unified mailbox restricted to Inbox).
Spam filtering is weak or missing compared to the desktop version.
QR/code import/setup often doesn’t work reliably (QR import/import from desktop).
Yahoo setup issues (Yahoo login/config blocked).

2026-07-21	Nd*****	It's not bad, and I used it for a few months. Unfortunately, the lack of polish made another email client more useful. For example, notification actions are critical for me, who filters a lot of mail from previews. I will very likely give it another go later. For now, it's just not the best choice.

2026-07-21	jo*****	Bro, y'all way too big, too experienced and way too ready to have "power consumption code" errors in your application, killing the batteries in just hours, c'mon... 🙄 get it together... you have zero excuse for these type of little mistakes. I tried the app on 8 phones of different brands and only those horrible Samsung ones worked as expected... that's terrible business, sad even.
