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).

2026-08-14	ja*****	this is great because you can add multiple gmail accounts without adding them as google accounts to be used on android. it blocks remote images by default which is good for security and performance.

2026-08-12	Sl*****	It's email. It allows me to avoid ads, but it does not allow you to block emails, and marking them as spam is useless. I thought these were selling points of the app. Pretty disappointing. Support requires you to download an entirely different app, which I refuse to do. I have zero desire to fill my phone with bloatware. I've had the same experience with it using Ubuntu on my laptop. I don't really like it, but there's nothing better out there. I have more to add, but Google said no.
