I have the exact same issue. My name is quite common and I registered my email address more than 15 years ago, so it looks something like <firstname>@<server>.

Now I get phone bills, internet bills, promo emails, subscription emails, two factor emails, and sometimes even bank related emails addressed to someone who shares their first name with me.

It's been years now. I've reported the emails, but neither the intended recipients, not the sending organizations seem to care.

I agree, my namesakes are idiots too and so are the companies who don't have a simple email verification system. :(
