Not everyone's cup of tea, but quite nice if one can afford it: I have my personal domain and a catch-all inbox. So if I want to register at acme-co.xyz I will just use acmecoxyz@my-domain.tld

Maybe I should start using random words though? Wonder if someone will go bananas seeing their brand's name on my domain.

Yeah, I've had to explain that a couple times already, usually when dealing with customer support or in-person registrations.

And a "malicious" actor can get away with pretending to be another company by spoofing the username if they know your domain works like that. I don't think this has reached spammers' repertoire yet, but I wouldn't be surprised.

Eventually I'd like to have a way of generating random email addresses that accept mail on demand, and put everything else in quaraintine automatically.
