Official Version And This App Thunderbird: Free Your Inbox

Thunderbird is a powerful, privacy-focused email app. Effortlessly manage multiple email accounts from one app, with a Unified Inbox option for maximum productivity. Built on open-source technology and supported by a dedicated team of developers alongside a global community of volunteers, Thunderbird never treats your private data as a product. Supported solely by financial contributions from our users, so you never have to see ads mixed in with your emails again.

What you can do



  • Ditch multiple apps and webmail. Use one app, with an optional Unified Inbox, to power through your day.

  • Enjoy a privacy-friendly email client that never collects or sells your personal data. We directly connect you to your email provider. That’s it!

  • Take your privacy to the next level by using OpenPGP email encryption (PGP/MIME) with the “OpenKeychain” app, to encrypt and decrypt your messages.

  • Choose to sync your email instantly, at set intervals, or on-demand. However you want to check your email, it’s up to you!

  • Find your important messages using both local and server-side search.



Compatibility



  • Thunderbird works with IMAP and POP3 protocols, supporting a wide range of email providers, including Gmail, Outlook, Yahoo Mail, iCloud, and more.



Why use Thunderbird



  • The trusted name in email for over 20 years - now on Android.

  • Thunderbird is fully funded by voluntary contributions from our users. We don’t mine your personal data. You are never the product.

  • Made by a team that is as efficiency-minded as you are. We want you to spend minimal time using the app while getting maximum in return.

  • With contributors from all over the world, Thunderbird for Android has been translated into more than 20 languages.

  • Supported by MZLA Technologies Corporation, a wholly owned subsidiary of the Mozilla Foundation.



Open Source and Community



  • Thunderbird is free and open source, which means its code is available to see, modify, use and share freely. Its license also ensures that it will be free forever. You can think of Thunderbird as a gift from thousands of contributors to you.

  • We develop in the open with regular, transparent updates on our blog and mailing lists.

  • Our user support is powered by our global community. Find the answers you need, or step into the role of a contributor - whether it’s answering questions, translating the app, or telling your friends and family about Thunderbird.

Thunderbird is a 100% open source, privacy focused email app.

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.

Desktop version is great and I have used it since inception. The Android app is just a warmed over k9 mail, and still has all of k9's deficiencies. Two glaring ones are no support for filtering messages (for example to automatically sort incoming mail) and the other, related one, is no autoresponder support. The desktop version has excellent filteration and the filters can be used to set up autoresponses based on details of the message. A curious failure.

Unfortunately the Android app doesn't support filters yet. This could be something we add in the future, though we don't know when. For now, please upvote and support requests for filters at connect.mozilla.org

Missed important emails I use Thunderbird on my desktop, but when I switched to using it on my phone as well, instead of the Gmail app, I miss several emails from a client because despite being configured to auto update and notify me, it didn't update until I opened the app several days later. I had also switched because I was hoping that the calendar that was on my desktop would be mirrored to the app, but the app has no idea of a calendar, so any invite I accept on my desktop is just lost.
