Thunderbird Android Update: K-9 Mail 6.400 Adds Customizable Swipe Actions

In what feels like the blink of an eye, four months have passed since announcing our plans for bringing Thunderbird to Android. The path to bringing you a great email experience on Android devices begins with K-9 Mail, which joined the Thunderbird product family earlier this summer.

As we work towards a modern redesign of desktop Thunderbird, we’re also working towards improving K-9 Mail as it begins its transition to Thunderbird mobile in Summer 2023.

Later this week, we’ll share a preview of K-9 Mail’s beautiful Message View redesign. Today, though, let’s talk about the newly released version 6.400.

K-9 Mail 6.400 Adds Customizable Swipe Features

Version 6.400 of K-9 Mail for Android begins rolling out today on F-Droid and Google’s Play Store. Dedicated to pursuing a modernized interface, the new version introduces customizable swipe actions.

K-9 Mail 6.400 introduces swipe actions, such as Archiving and Deleting. (Shown here in Dark Mode)

As you can see above, an intuitive swipe to the left or right can quickly delete or archive a message. But you’re obviously not limited to just those actions. You can customize both right and left swipe actions with the following options:

To configure your own preferences, open the app menu (the 3 vertical lines on the top left of the app), and then: Settings ➡ General Settings ➡ Interaction ➡ Swipe Actions.

Swipe interactions extend to the full message view. When you’re reading a message, simply swipe left to navigate to the next message in your list, or swipe right to back up to the previous message.

We also recently added integral OAuth 2.0 support for major email account providers like Google, Yahoo Mail, AOL Mail, Hotmail, and Microsoft (Office 365 and personal accounts).

Where To Get K-9 Mail Version 6.400

Version 6.400 will start gradually rolling out today. As always, you can get it on the following platforms:

GitHub | F-Droid | Play Store

(Note that the release will gradually roll out on the Google Play Store, so please be patient if it doesn’t automatically update.)

Try New Features First: Join The K-9 Mail Beta!

As K-9 Mail transforms into Thunderbird for Android, be the first to try out new features and interface improvements by testing the Beta version.

GitHub releases → We publish all of our releases there. Beta versions are marked with a “Pre-release” label.

Play Store → You should be able to join the beta program using the Google Play Store app on the device. Look out for the “Join the beta” section in K-9 Mail’s detail page.

F-Droid → Unlike stable versions, beta versions on F-Droid are not marked with a “Suggested” label. You have to manually select such a version to install it. To get update notification for non-suggested versions you need to check ‘Settings > Expert mode > Unstable updates’ in the F-Droid app.

Looks awesome! Do you have a roadmap in place for the iOS version of Thunderbird? I understand that your main projects are currently this & supernova, but I’d be interested in if iOS is just a concept right now or if there’s already any concrete plans. Either way, looking forward to both.

There’s an undeniable demand for K-9 Mail/Thunderbird on iOS, and we’re listening to each request. But right now there’s no roadmap, even if there IS a desire to ultimately be truly multi-platform across both mobile and desktop operating systems. We’re going to get the Android version out the door first, and then figure out what to do about iOS. This approach is simply down to limited time and resources given the other ongoing projects we have.

Hi I recently noticed that Mozilla Thunderbird is not available on the official Microsoft Store rather we still have to download exe files and give thunderbird access to modify system settings in order to getting it installed which is very insecure and adds a lot of attack surface.
My question is – Why isn’t MozTB available on the Microsoft Store yet?
Firefox was published in the store months if not years before.
A lot of Open Source software projects have published their Software in the Store.
And as far as I have heard, doing this is pretty easy when the publisher also has a Github account.
So is there a particular reason for not doing this or simply it was not being considered before but being considered now due to user request?

Stay tuned, we’ve been working on it 😉

Awesome eagerly waiting for that since you can’t download exes in non administrative user accounts on windows.
Awesome guys you guys are really awesome.
But please do it within the supernova release since that is a major release. And it will really help to scale the project to the masses.

It will almost certainly release on the Windows Store well before Supernova comes out.
