Exactly the same situation with me in terms of gmail address (although my names are less common).

I get so many other $MY_NAME emails, including bills (including multiple credit cards and things like Afterpay), deliveries, medical details/reports, family communications, etc, etc.

And it's very clear that quite a few online services blatantly don't verify email addresses, they just assume the email is valid and allow the person to start using it.
