Haven't seen his answer here yet, but I use Zoho. It has a free tier IIRC and supports custom domain.

Not sure how private it is, tho.

I use Tutanota I think it's a really good private email client.

I switched to hosting my own inbound mail. I mostly switched because after trying a few providers they almost all dropped some email that I wanted (not Spam, completely dropped) so I set up my own. It is quite nice to have full control over configuration, filtering, backups and whatever else.

Right now I am using a paid rely to send, but maybe I'll see how my IP's reputation at some point.

I've been using ProtonMail for a while now and it works very well, they also offer a drive, calendar, password manager, VPN; you can choose if you want all the features or just email.

I also tried Tutanota and they do a good job as well, they're a smaller company and don't have as many features as Proton but if all you need is reliable, private e-mail, it's a good option.

For privacy, I believe Proton Mail https://proton.me/mail has been the standard.

Migadu they are super affordable. Great service. Privacy focused.

ProtonMail because they're at the very least non-intrusive and don't have a track record of snooping through emails, google im looking at you mf

If I remember correctly cock.li is also hosting some really bad Nazi domains and has apparently no problem with that...

Honestly, gmail for bills and that kinds of stuff. iCloud for personal stuff. I do not really use email that much other than getting spam. I imagine that is true for most people. I do not understand why the privacy community is so obsessed with private email. Are you really using it for stuff that needs to be so private?

I use disroot.

For the Proton people. I learnt about a guy that ended up in a US court and they asked proton for all his emails and the handed them right away, no questions asked.
