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

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

K9 Mail on my phone, neomutt on the desktop.

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

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

Outlook. It's solid on android and windows

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).

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

Protonmail is the way

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

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.

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 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.

gmail emails

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

On Mobile: K-9

On Desktop: Claws Mail

Gmail. Never put much thought about it tbh

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

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.

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

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

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.

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.

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

It's not amazing, but works well enough.

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

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

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.

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.

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.

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.

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.

Gmail on mobile.

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