> Mine is just my last name @gmail.com. It is a rather uncommon name

I'm in the same boat. And uncommon, but not rare. I've gotten emails intended for my brother. One time, I got a collector emailing about something with a rental car crash that I previously got confirmation email for. Recently, a Dutch woman discovered email and think she has my email address. It's amazing how many websites don't verify email addresses.

Some asshole bought a Lexus and entered my email address. I now get his loan statements and service reminders, on top of the advertising. They are all from noreply@, of course, and I would need to know the password to the account to unsubscribe. Sure I could reset it, but I'm not actually sure if it's legal?

If Eurocrats really want to save the Internet they'd fine companies for sending anything to recipients who haven't been double-verified.

What does “double-verified” even mean? Though, in case you were wondering, GDPR requires continued consent for companies to use your email address; they have to delete it if they don't keep getting permission to keep it.

"Verified double opt-in" is a term of art in the world of email. It means you provide your address to consent to emails and you confirm the address with a link sent via email.
