Probably not much help but I purchased a domain to have my own email, I can then have a separate alias for every single login/site, that way I know who leaks my email and just move on to a different alias. I don't even need to manually create email aliases and can make something up on the fly. All emails then come to a single, private inbox.

Posteo (based in Berlin)

Huh, surprised nobody has mentioned Tuta Mail yet. Cheap monthly and annual plans, hosted Ex-US.

Plus I have a domain, forwarded through my tutamail account, so I have unlimited email receiving addresses, at-will. :)

No fascism, no privacy violations. I'm annoyed they don't support external clients and the mail rules are fairly limiting, but for my purposes it's well worth the costs.

Built in calendar also can import ICS files and it has effectively replaced Gcal for my own personal private use.

I use proton myself. I dont know about private browsers but it works with Thunderbird via its own decryption app Proton Bridge. Thats a good privacy solution (assuming its a secure desktop), and gives you a local backup of your email.

Fastmail 👍 Well worth the bucks imo. Super well thought out UI, private, and they work towards jmap over imap.

I run my email out of my closet. Postfix/Dovecot, using Mutt as my client.

I've got my own domain on Zoho mail, not sure if it's still free for custom domains.

But just for fun I might set up Stalwart with an SMTP relay through SMTP2GO or similar.

Postfix and dovecot on a server stuffed under the stairs.

I recently got Stalwart running with Bulwark as the front end to actually send emails. I have Stalwart behind Caddy for https and Stalwart only exposes http because I don't want to mess with pop and imap. Instead I have it using JMAP, which Bulwark is designed for, because it's simpler and more secure. Receiving emails works from some basic testing against my personal Gmail account. Sending email was a bit more complicated, but I ended up using SMTP2GO for outgoing mail and it worked in aforementioned testing. Their free tier is more than enough for personal email and I can switch to a different smtp relay in the future if I choose to.

Tuta (Germany) and Murena Workspace are good mail providers. Murena (France) apart is an excelent all in one substitute for GDrive and other Google services. They also sell Fairphone with own OS (eOS)

i use disroot mail. https://disroot.org/

Tuta and Mailbox.org

Mainly ignore it till someone calls me and asks “did you see that email?”

I've used most private browsers.
Never had a problem with Proton not working.

It doesn't use webgl, so that's not an issue. No idea what else you're blocking that could be a problem.

I use (and created) Port87. Its goal is to reduce spam, but the way it works has a byproduct of being inherently rather private. You give out a different address to each place.

It is not end-to-end encrypted, so if that’s a deal breaker for you, I’m afraid it won’t work. That might be in the extended roadmap, but there are a lot of other features I need to build first (IMAP, CardDAV, mailing lists, and a better composition experience are my top priorities right now).

I use mailbox.org because both proton and tuta do not support IMAP, which is generally needed to use a 3rd party client. Mailbox.org is also pretty cheap and is pretty private as far as the non-E2EE providers go. And in terms of E2EE it is going to be used so rarely that is basically doesn't matter, the type of person that would use tuta/proton would probably be willing to setup PGP with you, and E-mail isn't a secure communications platform anyways, so you might as well just use Signal, XMPP, briar, etc...

Nobody mentioned Posteo...

tuta, secria, murena

Mailbox.org is decent. But 1€ per month. I need to switch my stuff to it and pay before the trial ends.

Job. I job for email.

I use purelymail, I've been really liking it so far. They do like a "pay as you go" kinda pricing, so it ends up being pretty dang cheap, even if you get/send a decent amount of emails. Can use your own domains names, yadda yadda.

I might give self hosting an email server a go one day, but people seem pretty mixed on if its worth it.

Mailbox with encryption of incoming emails. It works with IMAP clients, and I own the keys. Other security minded people can also send end2end encrypted emails without needing to use the same provider.

Currently I don't use a privacy-focused mail provider because all of them suck in a way that demotivates me to put in the time and money to migrate and it's an insecure protocol anyways. But for privacy-focused email providers Proton seems like the least shitty option right now.
