I want to thank everyone who replied. I did some research on most of these and think PurelyMail is the winner for me. Feel free to correct me if I got some details wrong. I want to give a shoutout to @mbirth for mentioning Disroot, which looks like a really interesting experiment in federated services.

Also, I know this post is really bending the rules for c/selfhosted, but connecting your selfhosted services to an email provider is essential, and having a reliable and affordable email provider just makes this weird hobby of ours a little easier.

Have a look at posteo. Gives you IMAP so you can use any client. Its only €1 a month and is supposed to be good with privacy. Have had no complaints so far. https://posteo.de/en

Fastmail. It’s been around forever and it just works. And they don’t do anything weird with SMTP/IMAP.

mailbox dot org is also pretty good, but I wasn’t a fan of their 2FA implementation.

I been using mailo.com for years now. It's a small EU business that's been in business for 20 years iirc. Never had an issue. Other than that, I predominately use aliases that forward to my main email address.

Check out PurelyMail

Tuta ?

Purelymail is nice. Stupid cheap and really easy.

Mailbox.org

I can highly recommend MXroute. Just works. Great for integrations.

Nobody mentioning fastmail, sad times.

Mxroute for me. Or Zoho.

Mailo.com. French company. They have quite a quirky UI. like one can tell it's made by a backend guy and the junior version is made by his younger nephew but technical wise it's perfect. All standards are there plus price is OK.

I've using purelymail.com for a few years with my own domain, never had one problem, and they're cheap.

Runbox (Norway) is a good option, good privacy protection and outside of EU chat control zone

I've enjoyed ProtonMail quite a bit the last year.

Gmx for automatic emails to myself since the Calibre days. Maybe there is something better now.

Careful, I had a post like this locked almost a month ago.

FWIW, I went with purelymail, and it’s been pretty good. Basic, but solid.

I use inleed.xyz. It's free, has IMAP/SMTP access and you can have as many accounts as you want. It's limited to 1GB of storage shared between all accounts though.

I've got a so-called "Asteroid" with UberSpace. You just have to bring your own domain and configure DNS to use their servers. Unlimited mailboxes, unlimited aliases, Sieve scripts ... and SSH access.

Apart from that, I've got a free account with disroot for emergencies.

disroot is quite decent. I like their (privacy) vibe and the set of semi-independent services they provide.

I use Migadu, it's probably the closest you can come to fully managing email while not hosting your own server. All their plans are limited on inbound/outbound mails per day and storage used. Beyond that you add as many domains as you want (within reason on their cheapest plan) and create any number of separate mailboxes/users.

Disroot (Netherlands) is pretty good, that's one that I have used before, and I've also heard that Fastmail (Australia) and mailbox.org (Germany) are good paid options but have never tried either.

I've been happy with Fastmail and its web & android clients so far but I havent tried to integrate it anywhere yet.
