US thing I’m guessing? Here in Sweden, we don’t get much spam mail in the first place but you simply put a “no ads” sign on your mailbox and then only get the stuff you need. The 8 years I’ve lived in my current apartment I’ve gotten like 3 things that weren’t bills and stuff I need.

In the US you just shoot the people that try to put ads in your mailbox. Not a lawyer tho so idk. shrug
