I live in what was a family member's house before her passing in 2014.

I still receive her mail.

Here's the kicker: the mail is addressed to a name she hadn't legally had since the late 1970s. She divorced and remarried - which meant taking her new husband's last name - then lived another 30-ish years, died, I moved in, and it's been ten years of me there.

It's an insanely wasteful practice.

Write “rejected” on all the mail you don’t want and leave it unopened in your box. Cuts it down nearly to zero after a few months.
