Is this a good setup for sending anonymous/private emails from a custom email address?

I buy private domain from here [https://secure.orangewebsite.com/index.php](https://secure.orangewebsite.com/index.php) (icelandic free speech web hosting) using different sign up info and pay via crypto and then hook this domain up with protonmail private email service ([https://protonmail.com/support/knowledge-base/custom-domain-support/](https://protonmail.com/support/knowledge-base/custom-domain-support/)).

Would this allow me to send relatively private and anonymous emails?

Thanks.
