Android

K-9 Mail is my favorite. It will.be renamed in future to Thunderbird, because the developer is now working for them 😊

Fairemail is pretty much the default android client. Open source, full featured, not bad on the eyes. It just fucking works without hassles.

If anything, the settings are too feature packed, it can take a while to tweak everything if you really want it customized

FairMail is very good, and gets updates frequently.

Works great with Gmail, and other mail services.

When not using ProtonMail, I use FairEmail: "Fully featured, open source, privacy oriented email app for Android."

Another vote for FairMail. I've been using it for a few years at this point and never had a reason to look for an alternative.

I'll probably give K-9 a try when it eventually rebrands as Thunderbird though.

I miss Inbox

Spark. Absolutely adore it. Once I tried it, I've never gone back.

• On Android: K9Mail. By far the best.
• On Linux: ThunderBird. It's bloated like an obese whale on cortisone but I've yet to see a better client.

Been using for a long time because of the rich text email options. But it is awesome all around. My pick for best of the best.

Fairemail on android. Thunderbird on pc. K9Mail on android is also good but I prefer fairemail

I just wish Android had a nice email client that was material you and material 3 like Gmail and also wasn't Gmail

Thunderbird - a bit slouchy at times but featurewise I'm very happy with it :)

I used K9 for years but recently switched to FairEmail. Works better in terms of auto-completing addresses, has better sever-side search. Previously it looked horrible compared to K9 but lately it has added Material You and other attractive theming options. It has a rather intimidating level of options but is very powerful. That being said, I still like K9 and will probably continue to check in as they add features and become part of Thunderbird. Both K9 and FairEmail are really good in terms of being ad-free, privacy-respecting clients with unified inboxes, dark mode and other features most important to me. K9 has advantage of being totally free where FairEmail puts some key features behind a purchase, which I understand, as it's a solo developer.

k9 which will be become thunderbird mobile in the future

K9. Super happy in general, apart from push email not working properly most of the time

I use the default Gmail client but i highly recommend K9-Mail.

"Id like an email client with folders or categories."

I tried a few other email clients to see if I could ditch the gmail one (years ago, admittedly), and where those clients fell short for me was they didn't support labels, only folders. Multiple labels can apply to one email, but an email can only belong in one folder.

Does anyone know if things have changed, whether third party clients now support gmail labels?

I like Spark. I've had many interactions with the company and support out of Ukraine and they're always great. Haven't found anything better for my needs.

Tutanota, which is unfortunately my only option with my email provider lol. They have their own client which is really slow and clunky, but it has a simple view with my email, contacts, and calendar. It's all stored e2ee too.

Im with Samsung Mail happy.

I still like Aqua. I know.
