I‘m using notmyhostna.me as my email address and every time I have to provide it in person or on the phone I kinda regret it because people seem to not know much about TLDs.
People have no idea how email works (and why should they?).
1234 York Street or 1234 Miller Street
and they will not assume you live in York or work for the brewery making Miller Lite...
It's been 40 years, people could have wisened up how email addresses work.

And I always think: "you went to the effort to get a domain name and put a website up, but you couldn't go the one more step and have your email point there too?" Especially since you likely hired a web company to do the website, why didn't they also do the email? At least in these cases a company's web-savvyness (or grammar) don't necessarily affect their building skill.
