Android

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

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

Protonmail connected to my domain

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 🙄

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.

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

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.

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.

gmail emails

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.

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

On Mobile: K-9

On Desktop: Claws Mail

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

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

Gmail. Never put much thought about it tbh

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

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

Web portals. I use web portals.

neomut, because I have linux brain damage

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).

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

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

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.

Been using mutt for years, and I still love it. But getting it to works is more and more of a pain nowadays, and I find myself using whatever webmail my company uses (right now O365). For personnal emails, mutt on the desktop, and a selfhosted roundcube for when I don't have a client.

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.

Gmail on mobile.

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

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.

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.

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.

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.
