I use FairEmail. The free version already has fairly advanced features, it's open source and ad free, and you can customize it to your liking. Even the paid version is not a ripoff and feels like you are actually supporting the developer instead of throwing money at a greedy company.

K9mail. Mozilla collaborates with the dev. There'll be a Thunderbird for Android based on k9mail.

FairMail is great, and gets updates frequently.

I use FairEmail. It's very privacy focused.

Started getting tired of the ads in gmail, so last week switched to K9 Mail. Liking it so far.

Protonmail is my favorite email app/service. I've been using it the last 2 years and it's been a great experience.

I was using Spark for the past few years because it was the closest thing I could find to Inbox that supported non-Gmail emails. A few months ago they put out a major update (v3) that completely borked it for me. It constantly crashes on both iPadOS and Android, so I've moved onto K-9 Mail and am waiting for Thunderbird to come out on iPadOS.

I didn't use K-9 for the longest time because I had a poor experience with it the first time I tried it many, many years ago. Between then and now it looks like they refreshed to Material Design and have significantly improved the UX. I'm happy with it.

Bluemail is my app of choice. I have four different email accounts and like how easy it is to manage each of them.

Is there an email client that can sort emails by Primary, Social, and Promotions like how the Gmail client does? Also when using another client to send an email, all the email contacts don't get autofilled like how gmail has it.

I liked Spark, and right now I use E-mail by Edison. Clunky name, but good solid email app. Nice UI, multiple accounts.

I like K9 Mail, and it's cool that they're collaborating with Thunderbird to transition it to a mobile version of Thunderbird.

Been using Nine on my personal device, as Outlook was horrible at syncing with IMAP accounts (only synced on demand, never in the background). On my work device, I do use Outlook, but with an O365 account it does work as intended.

Tutanota has been great.

I like Microsoft Android Apps, and I always felt like Outlook is pretty good if you have O365. Zero complaints.

I bought Nine and used it for a while, but I just felt like it was a bit too cluttered for an email app.

Edison Mail. Multi-email account support mainly.

Proton mail all the way. Also signed for Pass for mail aliases.

Gmail, personally. Can't beat it.

Otherwise, I'd like to switch to Proto for the security.

I use protonmail and have a paid account there. They have filters that can automatically move mails to folders or give them a label.

I find Spark mail to have the best UI

I like aquamail but am not sure what is going on with already purchased paid accounts right now.

I love Apple mail. Super fast search through years of email, easy drag and drop between accounts, nice redirect feature. Unfortunately, I’m a Windows user at home and just can’t switch for one email client. I do use Macs at work though. Yeah, Gmail is a drag.
