Apple

I have found Mail on both iPhone and MacBook to be enough for my use. Otherwise I use and prefer Thunderbird on other operating systems.

Mimestream was promising in beta. The subscription model is too much for me though.

Outlook is good. Apple mail is good. But I still like Spark the best, I think. But I dislike Spark’s terms of service and feel like they don’t respect my privacy or data.

Inbox was so good, made email so easy. Can’t believe how long it’s been and no one has been able to replicate it. Still mad at Google for killing it off.

Gonna pop out the controversial opinion here and say I like the default mail app. It’s quick, simple, and does everything I need. The only thing I don’t like is that gmail doesn’t get push mail, but Google did that not Apple.

I hate that unlike iOS, mail does not run in the background on Mac though.

I require a functional snooze feature so Apple Mail is out. Outlook randomly deletes iCloud emails and Canary is too slow. So I am left with Spark on both Mac and iOS.

I keep trying other mail apps but always come back to apples. It’s just the best, clean interface, always works. Even ended up ditching gmail and going all iCloud, yay privacy :)

It’s Outlook for me. Trialed a bunch, disliked the data/privacy deets on many, and MS already worked it’s way into my heart via corporate America.

It does a nice job of pinning, snoozing, combining inboxes, and working cross-platform. FO FREE ;-)

I switch between apps often, but I tend to use Spark more often than Apple Mail/Outlook/gmail.

Thunderbird on PC

Default Mail app on Mac and iPhone

I prefer using the default mail app.

I use Mimestream. It’s a beautiful, well-made Mac app (for now, iOS coming soon) by a developer who clearly cares about making a quality product that adheres to the platform’s design language and usage idioms.

I absolutely do not begrudge him for wanting to make a living from it, and currently subscription is one of the only effective ways to do that for small devs.

I also don’t begrudge anyone who doesn’t like it. We all get to use our money how we see fit.

Thunderbird on desktop for my Gmail accounts and own domain. Built-in iOS mail app for those on mobile. Outlook web interface for work desktop, and Outlook iOS app on mobile to keep work and personal emails separate.

If you're on Gmail, buy Mimestream for Mac and never look back.

If you're not using Google for your email, and/or you're looking for something on iPhone then it's a tougher choice. I wrote an extensive review of the options not too long ago and landed on Spark, but your priorities may be different from mine.

Thunderbird on desktop, canary or stock mail on mobile

Some of the Google Inbox people did rebuild Inbox as "Shortwave" https://www.shortwave.com/blog/introducing-shortwave/

Which is available as both an iOS app and PWA. For those unaware, Outlook is also becoming a PWA.

I just wish the IMAP standard would expand to include contacts and calendar.

I don’t like how gmail shows ads even if you subscribe to Google One (I suppose this isn’t a problem on workspace accounts). I do like it’s rules to auto tag emails and the ability to set your own tags and rules.

Outlook app is a little bloated but it’s more functional than the native iOS mail.

Gmail is probably my favorite but since I transferred my domain to cloudflare after Google domains sold to square space, I’ve decided to use iOS mail again with my custom domain

I use Apple's Mail.app on both macOS and iOS (on Linux I use KMail). I keep hearing people don't like it, but it does the job for me. The only thing I'm missing from it is GPG signing/encryption support and having it automatically format what I write to 72 columns, but I can live without those.

(If I may ask, why do people not like Mail.app?)

Mail.app on iPad , iPhone and Mac. I see no need to change it. I wish the search was a touch better but it’s rarely an issue.

I use outlook on the iPhone and the gmail and outlook websites on my desktop.

Outlook does a good job of presorting my mail so I’m not bombarded with all the read at your leisure emails.

I still use Gmail over the native app because I instantly get the email when it comes in vs every 15 minutes or whatever it is without manually refreshing

On iOS/Android/Mac I like Spark most

Gmail for web, Thunderbird for client and Bluemail for Android.

I use Spark on Mac and iPhone. Multiple accounts with only one login is nice. Also being able to "done" (not a fan of the verbiage) all Newsletter emails at once is a must-have for me. I do miss Inbox though.

Spark for personal and Outlook for work. Really wish Outlook had the option to show pinned emails at the top like Spark does though.

I’m forced to use Outlook on mobile for work, so I have my personal email in there too. At least until Thunderbird for iOS gets made, at which point, I’ll find room for a second mail app.

Has anyone tried Vivaldi’s mail client? I use Mail right now, but the snooze function not working is kind of bugging me. Oddly enough, I lived without it up to now. Somehow, since they added it I expect it to actually work!
