I get "Dear Valued Customer" mail from companies that I've never done business with!
I have a friend that returns all the " sent thru the mail offers" he gets from companies back in their postage paid envelopes. He stuffs them full of whatever heavy paper he can find, so there is postage due when it arrives back to them. He says it's his way of supporting the US postal!
The next " whatcha earin' "
