Comments on Thunderbird: Free Your Inbox for Android

★★★★☆ Jaz Holder · Oct 14, 2026

Great app overall. Very easy interface with customizable options for swipe etc. love the unified account makes it very simple to view all mails quick a few improvements to make the app 5 stars. Implement a filter option for read or unread mails add a unified sent emails

★★★★★ Arockia Ferdin · Sep 24, 2026

Finally moved from ad-infested Gmail app to Thunderbird.

Why I can no longer import my e-mail setting from my laptop thunderbird to my mobile thunderbird? On the laptop an QR code is offered, but there is no settings menu as told on the laptop. OK, I just see, clicking on new e-mail obviously allows Scanning QR code.

Thunderbird is getting better and better. One thing I'm missing is create new maps in Thunderbird. It's possible on the desktop version but not in the android app version. Open source no shady data brokers that are able to use their email client to track and sell data to third party. Thunderbird is a clean mail client no nonsense.

★★☆☆☆ Nes370 · Oct 25, 2026

I was able to set up access to my email accounts, but the automatic fetcher never works. It's supposed to sync every 15 minutes, but the app only grabs new emails when I manually check. Likewise, I get zero notifications for new emails because it never checks. I have tried configuring sync intervals, notifications per email account in-app, giving thunderbird unrestricted battery usage, and explicit permissions to create alarms and reminders. Nothing seems to work.

★☆☆☆☆ Vorona Sira · Oct 14, 2026

1. For IMAP mail the app doesn't sync labels that were applied after the app downloaded the email. You check mail with this app, then your desktop email client applies filters and shuffles emails into their folders, then you refresh in the app again - all emails stay in one heap of Inbox. 2. The app refuses to sync folders unless you sync them manually one by one. 3. For decades, Thunderbird team had been refusing to implement export/import of filters. Now they don't even have filters in app.
