I've done this, but most of the junk mail I get is from previous residents of my home, even though I've lived at my present address for over 3 years now. I've called some of the frequent mailers and had some success. Others have impossible to find contact info.

I've talked to my letter carriers, and it will get better for a few weeks and then be back to normal.

I'd say I get 3x the mail for previous resident than I do for myself. It's frustrating. Would be great if USPS just had a form I could fill out that automatically stopped delivery for certain names (and gave that info back to the mailers so they could stop generating the waste).
