• GUI: Thunderbird
• TUI: neomutt
• Android: K-9 (soon to be Thunderbird)

I’ve tried basically everything under the sun, and keep returning to Thunderbird. Thankfully they’ve fixed the endless amount of performance issues with it.

Everything else is either in a horrible state, abandoned, or paid spyware that used to be a free project originally

Thunderbird

i've always used thunderbird and never had any reason to try anything else.

I use Thunderbird. I'm sure there might be other ones that are better, but it does the job.

The web browser.

FairEmail

Mutt.

Thunderbird is the best IMO. Mailspring is also pretty good.

Still using mutt after two decades (with isync for fetching).

Whats the best email service? I use Thunderbird for just about everything, but gmail has been getting on my nerves lately. I would love to selfhost, but my internet service provider blocks port 25...

kmail...
it integrates well with, you know...
kde...

I personally use Claws Mail.

They all fucking suck

I prefer Claws Mail. It does what I need it to.

Evolution currently. Previously Thunderbird. I wouldn't mind a newer client but I am only interested in native apps talking to my email server over open standards.

I've just moved to Thunderbird. I was never keen on the old design and found it rather clunky but the new UI I find much better.

I was using Mailspring but it has recently just refused to work on my device and I never even got a response on the community forums so I've just given up on it.

mail(1) or nedmail(1) is all I really need.

I prefer mutt/neomutt, but Thunderbird comes by default in basically every desktop-oriented distro I regularly interact with, so I end up using that most often on *nix. K-9 if I want it on my phone.

My true love is the combination of acme(1) and faces(1), but that doesn't do encryption/PGP stuff.

Thunderbird

I like Evolution. Has email, contacts, calendar, and todos all in one. And pgp support out of the box.

Sylpheed is the best. I thought everyone knew this.

don’t really have a favorite – started with Thunderbird a long time ago but switched over to webmail fairly early on

now that I’ve started to build a new system, I started to look around at the various options (and maybe getting off webmail or at least having local storage “backup”) – the standard GUI clients (Thunderbird, Evolution, KMail, BlueMail, Mailspring) seem to be … fine – but none of them really stand out

recently stumbled across some nice screenshots of aerc and the idea sounds really appealing, but I’ve never had any contact with terminal email programs and found out they’ve followed a completely different evolutionary path than GUI apps (even terminology has diverged between the two) – GUI apps keep trying to be an all-in-one (email, contacts, calendar, tasks, …) whereas terminal programs almost seem to to favor a “balkanization” of effort – aerc looks like it’s grabbed a middle-ground, you can run it as standalone or go all in with a fully customized setup – problem I’m running into is I can find lots of “how” guides, but very little in the “what” or “why” side of things …

I use Thunderbird if I'm using Plasma and Geary if I'm using Gnome

Thunderbird’s not bad, but I usually use web stuff.

I have an existing iCloud e-mail that I haven’t had the time to switch off of. I then use G-Mail for school stuff - since I’ve signed away my soul to Google anyway, might as well use what they have to offer.

Maybe one day, I’ll start my own personal e-mail utopia, nut that day is not today.

I'm not a big email user, tried some of the clients multiple times and always return to web.

Gnus, aerc, neomutt

To be honest, i still use Geary. It has a nice UI, and if you just read and write a small handful a month it still gets the job done.

I have everything aggregated into Gmail, so I just use web and the mobile app. I'm looking at Proton but it doesn't have the "send as" feature for external SMTP services the Gmail does.
