Comments on Thunderbird: Free Your Inbox for Android

★★★★☆ k erd · May 28, 2026

Unified inbox is very good, but there is no unified sent box Folders should also unify like in the desktop app. Search also automatically trigger server search, in the case of unified folderd, it should send server search requests to all accounts

★★★★★ SK · May 28, 2026

Have trouble in repeated authentication failure on Android 15, push notification not working and late email arrival. So far no issues with Android 16.

★★★★★ Alex · May 16, 2026

Thunderbird is a really handy very nice mail agent and now that it is also an app for Android is so great, love it :)

★★★★★ Eduard Stadtler · May 31, 2026

Excellent. Why people are so stupid using web mailers? I use it to store my e-mails locally, since I can search with many filters, very quickly ten thousand e-mails for keywords in the subject line or full text, or sender or can sort it by subject, date, sender etc. It finally turns your masses of e-mails info an excellent database. I have 20 e-mails in it and partly with 50,000 e-mails in which I can quickly search with keywords.

★★★★☆ Simanta Karmakar · May 10, 2026

Nice app if you want an alternative to the Gmail app. I log in my Gmail here and its log in fine, but when I try to log in my Zoho Mail, it cannot.

★☆☆☆☆ Jon Kipling · May 17, 2026

Trash. Does not load emails on time, does not provide notifications, and doesn't load app badges.

★★☆☆☆ M Jackman · Jun 6, 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. I also wish to customize unified inbox, so it doesn't include every account, like separated aggregated work, personal, but ignore this when it currently even refuses to run scheduled fetching in the morning just because flight mode is used at night

★★☆☆☆ J B · May 23, 2026

After a week of use, 1. An email had sat in the outbox for a week. 2. Searching a gmail imap inbox requires me to submit a search, takes me to an empty page, then explicitly submit the query to the server again (why?). Needs refinement.

★★☆☆☆ N. Ebneth · Jun 5, 2026

You can't insert signatures or hyperlinks mobile. The app on my smartphone always opens with the empty outbox of my main account. To fix it, I uninstalled the app, deleted all cookies, tried other things, nothing worked. Notifications don't work. The app works on laptop, but for mobile you should consider alternatives. On desktop version, I have no idea how to search for a mail. On the smartphone there is a search icon, but no similar option on the desktop version. I'll look for another mail app

★☆☆☆☆ anchor · May 6, 2026

For Gmail accounts, it shows only the outgoing folder. Unusable.
