Comments on Thunderbird: Free Your Inbox for Android

★★★★★ David Cowling · Aug 11, 2026

So far so good. Took a while on android to get the notification settings correct. Seemed to be a lengthy process but works fine now. So much better than Gmail

★★★★★ Ajay Verma · Aug 1, 2026

⭐⭐⭐⭐⭐ I've been using Thunderbird on Android, and it's been a great experience so far. 😊 The app is simple, fast, and easy to set up. I like that I can manage all my email accounts in one place without any ads. 📧🔒 It feels smooth, reliable, and privacy-friendly. Definitely one of the best free email apps I've used. Highly recommend! 👍

★★★★★ Maydel Fernandez-Alonso · Jul 20, 2026

It works great for my work email. Much better than the Outlook Android app. It automatically detected my configuration from the Thunderbird desktop app, which made the set-up process very smooth.

★★★★☆ M Jackman · Jul 13, 2026

Draft incorrectly saved into quoted email field, showing attachment icon when no attachment, missing elements in fetched email, or failing fetching email, delay>1 day despite being set to fetch every hour. I hope this thing just works, but it doesn't. It currently even refuses to run scheduled fetching in the morning just because flight mode is used at night. Re Dev: Yes it's been excluded from every battery optimization possible and is locked in background but still. Hope updates will be better

★★☆☆☆ Jari Kujansuu · Jul 30, 2026

Missing summary view showing subscribed folders from all accounts like Aqua Mail. It would be a good way to get overview of all received emails. Sidebar uses giant font and large spacing and no way to adjust. Result is a lot of wasted screen real estate and ugly visual appearance.

★★☆☆☆ qwe rty · Jul 10, 2026

It doesn't work at all. I use it in my laptop, so I tried to download it for mobile (S22 Ultra) and import my mailbox there. The app can't scan QR code, it simply does not react on it. The app has lots of buttons for scanning QR Code and all of them opens same window / activity which doesn't work at all. I scaned the same qr code from desktop thunderbird using phone system qr code reader, saved data to file, tried to import account through the file and app returned error 😭

You have to work on it. Unified Inbox doesn't work. When I switch from the Unified Inbox to another user account, I can no longer switch back to the Unified Inbox.
