There are going to be two clients for an unspecified period of time. Same code base, different branding. It's not possible to take an existing app released through the app stores and rebrand it. The new Thunderbird app will have import tools to help folks transition.
I mean you can rebrand an app, just not the package name. And users won't see that. So they could rename it Thunderbird even though the package name would stay "com.fsck.k9". It's not at all uncommon.
Though I'm sure they have their reasons for not doing that.
I've been using Betterbird for a good 6 months and it's the best email client I've used, it's what Thunderbird should be out of the box. With the Proton bridge app running in the background it integrates very well.
What have you been using instead? I've been using Thunderbird since I was 13 at least, literally never used a single other desktop mail client since then. So I wonder what other mail clients people use.
I’ve been an Airmail (Mac) user for many years now. But it’s been really buggy lately and there’s no motivation to fix the issues apparently. So I switched to Thunderbird about a month ago after a lot of research. It’s … ok.
Search is great.
Seeing stats/charts on my last 20 years of emails is super interesting.
Composing emails is not great, but I use a markdown plugin that makes it better … but it’s still pretty bad UX.
I hate the way it quotes previous emails with “>” for each line instead of an indented block quote. Maybe I’m missing the setting to turn that off.
I miss having an avatar/icon for each sender. It let me quickly visually scan my inbox for the person I want to talk to instead of parsing through all the text.
The spacing of elements in certain places is weird and inconsistent. In places where it’s too tight it feels cramped and bothers me.
You can’t compose a reply inline. You just have to use a floating window on top of the rest of the app.
I miss the one-key shortcuts to label and archive emails. This was originally a GMail feature and Airmail also implemented it.
Sending an email doesn’t happen in the background. You have to stare at a progress bar modal while it sends, and it seems to take forever. I just want to move on to my next email but I’m stuck waiting.
The tabbed interface is really nice. It’s definitely an underrated feature.
I wish it had super advanced rules like you get with MailMate. But what it offers is fine for 99% of users.
Again, I might be missing some settings to correct some of these issues, so take it all with a grain of salt. But these are my takeaways after about a month of usage.
