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.

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

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

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

ProtonMail, Simple Login, and FairEmail.

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

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

I use k9 mail for my personal mail.

Thunderbird with Lightning to reproduce all the outlook functionality

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

I only used K-9 Mail for years

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.

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.

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.

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

PC - Windows: eM client

PC - Linux: Geary

Android: FairEmail

K9 Mail on my phone, neomutt on the desktop.

Gmail on mobile, Gmail website on desktop

Outlook. It's solid on android and windows

I ❤️ FairMail. It is so customizable and versatile, I even bought the pro version for support.

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.

Spark for Android

Thunderbird!

Desktop = Thunderbird

Android= AquaMail

For Gmail users on Mac desktop, I really can’t recommend Minestream enough, if a paid app isn’t a dealbreaker. It’s designed by ex-Applers and implements gmail’s API completely— even to the point of the signature editor and vacation auto responder and having a mode that only shows unread messages and starred messages in your inbox (which is kind of a badass way to stay on top of busy mailboxes).

Protonmail connected to my domain

On Android I use Re:Work, like interface the best. Before that I have used previous app from the same developer (I think it was Nine mail?).

On Windows I really disliked Thunderbird, so currently testing out emClient.

Patiently waiting for Thunderbird on mobile with k-9 so Gmail it is atm

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

• On my desktop: GNOME Evolution - but only because my university uses Outlook w/ Exchange (cringe) and the UI is slightly more tolerable than Thunderbird.
• On my phone: I just use the baked-in Samsung Mail app.

In terms of provider, I used to use Gmail for my personal, but got tired of Big G scraping my correspondence. I tried Proton, but its integration story is a complete joke (you can upload your calendar and contacts but there's no DAV support, their IMAP bridge is a non-standard-compliant dumpster fire that doesn't work with half the clients I tried...) so I ended up on Fastmail.

Web portals. I use web portals.

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

Thunderbird has worked well for me

neomut, because I have linux brain damage

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.

Protonmail is the way

Big fan of outlook tbh, it works well and both on iPad and android

Literally just started using k9 mail on my phone and it is amazing. It just does all of the setup for you.

Been using K-9 Mail because they support OpenPGP. Also, their user interface is miles better than FairEmail's.

gmail emails

I've probably tried every client out there and repeatedly keep exploring, but I always end back on Newton

Web based only here. I have multiple address though so the "client" varies. Outlook, gmail, Proton.

Gmail. Never put much thought about it tbh

I use Tutanota's clients, and enjoy it. Haven't had any issues, was a great replacement to the unencrypted privacy-invasive Gmail and Google Calendar, sorting to folders has been even more convenient

I use Em Client on desktop and I love it, on android the Em Client app is still in beta and quite unstable so for now I'm using outlook. Looking at the comments I should give K9 a go.

Edit: Switched to FairEmail for Android

It's paid (one off $15 I think), but has a two week trial but I've been using Nine for a few years now, pretty happy with it.

Just remember what the Magic 8-ball says when you drink the water inside it… "Outlook is not good!"

Really, though, I know the 'me' of about 20 years ago would be shocked to hear this, but the whole Microsoft suite with Outlook is pretty comfortable to run and use. I use it when hosting websites for my business, and it's always worked how I needed it.

Beyond that, I used Thunderbird for years and that's my go-to client when I want to go free. It's easy to set up and people usually love using a Mozilla product.

Careful if you're using Outlook on Android. From what I've read, it doesn't actually locally handle non-exchange accounts like IMAP or POP3 (why are you using POP3 though). It's done on Microsoft's servers, so your basically giving Microsoft your e-mails. I'm not sure what kind of access they get to them from the privacy agreement you probably just clicked past.

So Outlook in Android users Microsoft servers to fetch your mail, and the client just shows whatever the server got.

I've migrated from just using a gmail account to using Anonaddy which point towards a Tutanota email. The migration was PAINFUL, but glad I persisted and went through with it.

i'm just using tutanota since they don't work with 3rd party clients

I manage my e-mails with Blackberry Hub. (On a Fold 4).

It's not amazing, but works well enough.

I have recently pivoted to proton..

Apple Mail on Mac and iPhone, because it’s simple and it works well.

Although my main one is gmail, I have been using proton mail for a while and I'm getting to point where I trust it for most stuff and I will start to move non-critical stuff away from gmail.

I'm moving to Tutanota so I have to use there client on desktop and mobile. I have Thunderbird for my Gmail and Outlook emails on Desktop and just use Gmail and Outlook apps on my phone.

Gmail on mobile.

Thunderbird on the desktop. I keep TB running all the time to do filtering. Google filtering is lacking.

Every time I try a different email client (on the desktop) I always go back to Thunderbird within a few days. Within the last few months I've grown to love a T-bird fork called "Betterbird" which seems a lot snappier and more responsive than the "official" bird.

Tutanota for email + calendar. It's entirely foss, can be downloading from fdroid, doesn't require Google play services, and is fully e2ee so nobody can access your data except you.

on desktop I use eM Client. On Android I was using just plain GMail but I saw people in this comment section using other stuff so I checked it out and swapped to FairEmail.

edit: FairEmail is fantastic and I've upgraded to pro. Definitely recommend this one for mobile users with multiple email accounts.

Used to use Thunderbird but I wanted something that just looked like it was from this century. I like how eM Client works and its features and it looks nice. I don't like that I am limited to 2 email accounts though. I'd love something like it that is FOSS and allows more email addresses.

I actually swapped to Protonmail last night. Took awhile to change the email address on everything, but worth it. Trying out the free version for now, keeping my Gmail as a backup and for Android.

KMail for Linux (KDE) and K-9 for Android. I used to use Thunderbird, but hit a couple of bugs that just wouldn't go away. Absolutely love KMail.

I use thunderbird cause I saw the new logo and thought it was cool.

Outlook mobile seems to be the only one to give mark as read function on the galaxy watch. That's the only reason I use it.

I haven't figured out a reason to use a separate email client up to this point. I just use the webapps for Gmail and Fastmail.

On desktop I stick to the wonderful (for Gnome users, at least) @Geary.

On Android K-9 is fantastic, but regrettably I'm currently using the stock Gmail app because I had trouble setting up my Office365 work email. :(

TypeApp

I'm clinging to BlackBerry Hub+ because unfortunately I have not yet found an alternative that does the multi inbox (+ texts, signal, ...) on the same level.

no client - firefox containers for when I'm forced to use gsuite (work stuff) so I can keep different gmail tabs open without cross contaminating the cookies. And ProtonMail for personal (also in its own container).

K-9

I am with Google Workspace, so most of the time I would use the website, but if I had to use something, it would be Thunderbird on Desktop and Spark on Mobile.

Protonmail + Duckduckgo's email service, which links to a preexistent email (proton in my case) and allows you to clear trackers from emails and to use randomly generated email adresses.

Edit: only now realized that you asked for client, welp, I use proton's client, but I've been considering using thunderbird lately

Thunderbird on the desktop; K-9 Mail on Android.

Spark on both Android and Win. The AI integration is surprisingly useful, albeit I think a paid feature. I also personally like the look of the clients and they are pretty fully featured.

Twobird

I use K-9 on mobile and Vivaldi on desktop.

Used Eudora long ago. As its support dropped and Qualcomm's development of Thunderbird took off, somewhere during that I embraced the spiritual companion of Firefox. I have to use Outlook at work, that helps me not consider changing at home. Also jumped on the Gmail bandwagon back when you had to get an invite to participate. It was just a side email at the time with storage built in, but when my original ISP provider finally threatened to charge me for having an email account, I moved everything over and linked Thunderbird up to pull from Gmail.

Also using outlook. I can say for certain there are some bugs with IMAP email accounts, but other than that it has been working well for me for years.

The only thing I don't like about it (other than the IMAP bugs) is the notification sounds that are exactly the same as my work mail on PC. I get jittery whenever I hear those sounds.

Since google threatened to end legacy gsuite accounts I ended up migrating my email to another service (Namecheap).

Because of that I also had to use different email clients.

Desktop - emClient (prefer this to Thunderbird)

Android - Spark

Both work pretty well for me so far.

I've been using Spark and remained using it especially now that they have a desktop client it's just so clean.

Work Desktop: Microsoft Outlook Work Mobile: Microsoft Outlook Home Desktop: mail.google.com Home Mobile: GMail android app

Why? Because I was on Proton personally for a long time but got frustrated with the lack of features and also my wife and I rely heavily on shared groupware stuff like calendars and reminders, so we switched back to Google Mail. Once Proton is a bit more feature-rich, we'll take a look at it again.

Thunderbird on desktop, fairemail on android.

Tried Fair mail and k-mail and they are ok... Liked Outlook but came back to Gmail since it can't be removed from the device anyways..

Not exactly just a client but a client and a service: HEY from 37signals (formerly Basecamp).

I've been using it for a year and a half and I really love it.
