For anyone who was using K-9 wondering why Thunderbird looks no different, it's because they aren't different.
They build both apps from the exact same codebase. Only difference between the two are the default color scheme, the branding icons, and the text strings of the application's name. It's literally just a choice of which brand skin you prefer.
Which, honestly, kinda cool. A virtually zero-cost way to keep a few K-9 stans happy.
I'd say customizability. Haven't used k-9 since I found FairEmail so can't really say anything about how it is now but it used to be pretty bare bones. At least compared to FairEmail.
I agree, it's kind of funny in their website claim they don't put "bells and whistles" in their UI yet it looks way cluttered compared to K-9/Thunderbird.
No doubt it can work better than the aforementioned but it'd be nice if their devs could be a bit humble and recognize its UI could get some love and it would be beneficial for FairEmail.
For me it definitely looks different, are you sure you have the new version...? They've updated a lot of the UI elements to material design 3, but kept all the same layout and whatnot
I really like it so far! Feels like a really welcome refresh
Is there any advantage over my phone's stock email client, considering 99% of my emails are confirmation emails from online shops and similar stuff and I hardly ever actually send an email to anyone or receive one from an actual person anymore?
Well, an unbranded build would be perfectly possible, like how "Fennec" is just a build of Firefox. In case they continue to release updates for K-9, that would be an unbranded app right there...
Downside is it appears using openkeychain is not working for encrypted emails. I fill in the settings but it still won't show it, even after closing the app and reopening.
Edit- it works now. No idea what I did it didn't do.
