I understand how to block and/or filter email, but how about regular USPS mail. Is there a good way to stop the junk? I can’t imagine how many trees it takes to make all the flyers and papers I get in the mail that go straight to the recycle bin. All those resources (postage/paper/money/time) spent and all the mail gets is a half-second glance, what a waste!
I don’t mean through USPS. I understand they have to deliver mail that has paid postage. I’m asking if there is a way to get my address removed from the sources’ lists.
