Yeah but it's email, you either trust a service or run your own SMTP server and have your email get sent to spam every time, and recieve a shit ton of spam. Point is, Protonmail actually offers a good service for what it is, but too many people expect perfect anonymity when using a clearnet, unencrypted ancient internet protocol. Very silly.

We're in the first part of the second quarter of the 21st century; personal email servers basically get solid spam filtering out of the box these days. 😎

Yes, but unless your IP & domain are at the top of the "nice" (rich and well-connected corporate) lists, your sent mail isn't going to be delivered.

That's bullshit. If you have a domain & DNS already, you're good. Grab a @LNVPS.net host, setup your server & go.
