Comments on Thunderbird: Free Your Inbox for Android

★★★★★ Mark Taylor · Aug 16, 2026

I've used Thunderbird PC client for years and did not know this was available, Brilliant App, works well on my phone, very pleased with the ease of set up and adding multiple emails accounts, and also the unified mailbox, but especially like the no ads and no data shared with third parties

★★★★☆ 4 psw · Aug 27, 2026

Been customer, on and off, for years. The rethink, a while ago, was shocking, rough, and clunky. But starting essentially fresh can be all that. Restarted using this version maybe 6 to 12 months ago to isolate a few Gmail accounts from phone's too inclusive automation. Thanks muchly for that. And, just discovered email account icons/graphics are editable (text and color), and can now reorder the list of accounts. Hoped for these since the rethink, so thanks again. Gettin' better folks.

★★★★★ Pramod Dematagoda · Aug 19, 2026

Great open source email client. Unified inbox is great. Only suggestion is that it might be cool if you can perform a server search at the unified inbox level.

★★☆☆☆ Codey Jackson tax · Aug 20, 2026

This app has been a real let down so far. I'm a long time Thunderbird desktop user, and I've been waiting on an Android version for years. I've been using this for a few months now, and I'm about ready to go back to my phone's default email app. I'm constantly having emails not send and the UI really could be better. Hopefully improvements come later.

★★☆☆☆ David Scheiber · Sep 10, 2026

I just want an email client that works :(is that too much to ask? I switched to Thunderbird because Gmail would fail to send messages lock up and crash way too often. But it turns out Thunderbird has its own set of problems, the search function straight up doesn't work, and sometimes it will fail to send messages and will not give me any feedback and why the message failed to send.

★★☆☆☆ Mel T · Aug 21, 2026

Wanted to like this app; I like the desktop version of Thunderbird. Sadly the app is laggy and unreliable, with emails arriving hours late despite checking all the app/phone settings to allow instant syncing and notifications. Seems like it's a common issue people have. Have switched to Blue Mail

What happened to the Unified Inbox? Works on the desktop but not mobile 👎👎
