Android

I quite like using K-9 Mail, it merged with Thunderbird and great things are coming for it, I think it's awesome

Gmail because I'm super boring and it works.

Except that now I have to use Outlook too cause Uni moved from Google to Outlook

K9 mail on Android since many years and Thunderbird on laptop, also since many years. Also use Gmail, Yahoo Mail.

Please don't hate me, but I use the Gmail app on Android since it works well enough.

On my desktop though I use Thunderbird, and have for about as long as I can remember.

Thunderbird is the best. Been using it since many years and had no major issues.

K-9 on Android, Thunderbird on desktop!

I use ProtonMail. Additionally, i have set up e-mail aliases with my domain - i get e-mail addresses like kbin@mydomain.com, or personal@mydomain.com. Its quite useful when i suddenly get sent a bunch of random spam e-mail.

I can then just block that e-mail from receving e-mail, its quite handy.

K9 Mail is my favorite one so far. I've tried FairEmail but the UI was confusing.

Nine, best for a full Outlook experience and a calendar color picker

I like FairEmail on Android and don't see myself switching to something else anytime soon. For the desktop I use Thunderbird

• Android - K-9 mail
• Desktop - Thunderbird

I mean, thunderbird has been around forever and it's never done me dirty.

ProtonMail, Simple Login, and FairEmail.

I use k9 mail for my personal mail.

I use FairEmail, too. I didn't like GMail and K9.

I only used K-9 Mail for years

Thunderbird with Lightning to reproduce all the outlook functionality

• Desktop: Thunderbird
• Android: K-9 Mail

On Android I use FairEmail. I prefer it for it being FOSS.

Edison. I use it on my Pixel, iPhone, and iPad. It has some more advanced features I don't use, it just has a simple, straightforward UI on iOS and Android and doesn't hassle me too much about upgrading to paid features.

ProtonMail :) (Edit: Oh i see client! (no matter as long as it works with ProtonBridge, or just web UI)

K-9 on Android, Thunderbird on desktop. I love both of them, but K-9 has some weird problem that background sync appear to be not working.

Desktop = Thunderbird

Android= AquaMail

Thunderbird!

Spark for Android

Outlook drains my phone battery so fast I cannot use it. Stick to FairEmail now.

PC - Windows: eM client

PC - Linux: Geary

Android: FairEmail

Outlook. It's solid on android and windows

Used Gmail for a long time, 2 weeks ago switched to Outlook and simply amazed. It's easy to use, doesn't show you any ads unlike Gmail. And keep tracking the mails is much more enjoyable compared to Gmail. I believe it can do more of that if rules can be applied to Google mail accounts.

Gmail on mobile, Gmail website on desktop

Thunderbird on the desktop, Aquamail on Android, RoundCube/SquirrelMail via the web in a pinch. Back in the day I also used Evolution on Linux (when T-bird was buggy and lacking some features). Despite having many email buckets in the cloud, I keep no mail in any of them. I've self-hosted since '99, so I've been able to do whatever.

I did use Outlook back in sepia times (pre-'98) and used Pegasus and/or Pine before that. :p

I started using Spark late last year. It's simplified my mail handling quite a bit. There's also a desktop client for Windows, Dunno about OSX and IOS.

I used outlook for years. Then they threw ads in between emails... I instantly deleted outlook and haven't looked back. The last place I want to see ads is my fucking email 🙄

Either k9 or the native email client (Samsung Email, LG Email, ...) when they have a good Systemwide integration.

Thunderbird has worked well for me

I used Aqua Mail Pro for years and it's fantastic. They're switching to a subscription model for $30/yr so I switched to Samsung email.

I used AquaMail for years, but they just decided that this fall they will go subscription, and old paid users who bought the app will not get all features. So, I've transitioned to the paid (one time purchase) version of Nine email app(by 9folders). It is equally capable, working with my free accounts and my O365 corporate account (including synching calendar). I looked at several open source options, and none were competent to deal with my Work O365 stuff.
