As others have hinted, there's a tension here. Confiscating big tech's access to your email is a major privacy win. But putting your actual name in your email address is... not so much. At the very least you won't even have the option to obscure your identity from a correspondent. If you have a website at that domain, it too will be chained to your email identity, thus telling your correspondent all about you.

These realizations led me, personally, to ditch my whole setup of own-domain email. If the domain is going to be a pseudonym, might as well save some money and just use a pseudonymous handle at the email provider's domain. That's what I now do - with one of the privacy-respecting email hosts, of course.

Then it's a hassle to change host later, you say? Yes, a little, but here arises another paradox: from the perspective of privacy, it's actually an advantage to changing one's email address from time to time.
