I recently moved all emails on personal domains to Cloudflare Email Routing [1]. It works flawlessly and you can setup ProtonMail or whatever other email you want as your private address that everything gets forwarded to without having to reveal what the destination address is.

For sending email, I setup an SMTP relay via Amazon SES. If you verify your domain, you can send an email from any alias.

This combination works great!

That's a lot of moving parts, I don't think I'm comfortable juggling cloud infrastructure across three vendors just for e-mail. Also, I guess being US corporations AWS and Cloudflare still have to hand over any data a US agency requests.

Regarding SES, beware they force a Message-ID header, preventing at least forwarding of mail without breaking threads. There are probably more gotchas to this I hadn't discovered.
