If I get junk mail I don't normally open it. What to do is blank out your address with a black pen, circle the return address on the back, scrawl an indecent comment and stick it in a post box. If there is no return address I open it to get the name of the sender, blank my address, write on the envelope "return to ????" and again stick it in a postbox.

Now if a few hundred or even thousand copy me junk mail will soon be history.

I've never actually done this at home as we don't get much junk mail at all like we don't get spam phone calls either - signed up to TPS (telephone preference service) and MPS (mail) - seems to work....
I've definitely done it at work though
