I use fastmail for this. It works great although my email address sometimes confuses people. For example, a small company I ordered something online from called me to ask why their business name is in my email address. I have 2 separate domains going to the same inbox, each domain can have any subdomain and email address I want. I can send emails from any of those addresses as well.

You can add a rot13 transformation on the company name (if there is a human on the other end), to be less confusing for them.

Nice tip. I've encountered the same thing. Love to see an email generator using this automated in bitwarden/keepass.
