The previous owner of my home - apparently an avid shopper by mail - moves 3 years ago and did not leave a forwarding address. I've unsubscribed the address from dozens of catalogs and charities, but it seems they've sold her information, because about 90% of my mail is still addressed to the previous resident. I'm fed up! I've taken it up with the post office, but they just tell me to discard her mail.
