If what you want is private/secure encrypted email that the provider itself can not even read, I recommend you arcanechat.me

A couple months ago, I would have said Proton. But....

Here we are.

Buying your own domain.
You can then use whatever provider, or host your email service... but at least you don't need to change addresses when switching anymore.

disroot and autistici have been providing decentralised communication services (like email) free of cost for many years. They are both run by activists and survive on donations, and they don't spy on you or get any money from your data. Also they run freedom-respecting software, so all their code is publicly auditable.

I will always recommend Posteo. https://posteo.de/en

Mailbox.org

Mailbox Standard compared to ProtonMail Plus:

• Cheaper (€30/yr vs ~€50/yr; if you don't need custom domains, €1/mo)
• More aliases (25 on mailbox, 50 on own domain. Proton has 10 TOTAL - why custom domain aliases are counted against Proton ones does not make sense to me.)
• Support for any number of custom domains AFAICT (Proton Plus supports only one)
• Trial account is not allowed to send emails, so fewer issues with services blacklisting proton.me and protonmail.com for spam (hasn't happened to me, but I have heard of some cases)
• Can use a regular email client (security tradeoff for E2EE messages - but there already were plenty of discussions on whether E2EE has benefits, especially sending mail to other services)

Just leaving my vote for fastmail. They are wicked.

Proton, but I've been questioning that of late :-/

How about Tuta mail with a custom domain? They have unlimited custom domain addresses which is pretty nice

Mailbox.org

Everything is better ;-)

i.e. mailbox.org, posteo.de; there are also protonmail and tuta.com, but they don't have IMAP

Perhaps an indirect answer, but I'm using a duck.com forwarder whenever i need to give any address, these days. On top of tracker filtering and random alias generator, once i change addresses I'll only have to update the forwarders destination.

If you really wanna get started with your own domain I highly recommend just getting https://purelymail.com/ setup for the hosting provider. It's going to be way cheaper than just about anything and you pay for what you use. I've been on it for a few years and never had a problem.

I've been using Tuta for damn near a decade, and it's been great for me.

This dude compare quite a lot of email providers in term of privacy. I do not necessarily agree with all its critics but it is a useful resource:

I would recommend to buy your own domain in case you need to change again. That way, you're not trapped by your email provider and you can change in case you're not satisfied anymore

tuta

mailbox.org and posteo are my recs

Posteo + Addy.io + Thunderbird

I'm actually busy setting up my own mail server. On my own infrastructure, using public static IPs etc. I'm done with all these other mail providers. I'm going back to the start.

Another one for Tuta, with addy.io as a proxy service. Nice integration with Bitwarden for making new accounts + it's simple to make rules based on the to address for easy filtering.

I've been using mailbox.org, and it's pretty great. It's cheap, it's private, and it works well.

I like the idea of e2ee email, but the way they all work it's pretty much a completely useless feature for most people, myself included, and I also like using Thunderbird. It's just not worth the trade off for something I'd basically never get any use out of anyway.

I'm using Infomaniak Mail and am fairly happy so far. They are based in Switzerland and I get custom domain + 5 user accounts for 1.50 EUR/month. I've tried other providers but coming from Gmail I like that their webmail displays email conversation like Google does whereas most other providers just run rainloop or roundcube where threading support isn't quite the same.

Their android app is open source too and can be installed from fdroid. It can be a bit sluggish sometimes though, but K9mail/Thunderbird works fine too.

You can search lemmy for keyword email, and 99.99% of recommendations will be better than Gmail.

Tutamail, they have direct access by fdroid too
