I can't believe it took me this long to think of this. 

I don't get much snail mail.  Maybe a few pieces every few days.  Not a big deal.  Apparently, as soon as you get a mortgage, anybody on earth can mail you anything they want.  But like I said, not a big deal.  I feel slightly bad that I throw out pretty much everything that's mailed to me.  It's such a waste of paper and postage.  I wish there was something I could do ...

And hence the national Do Not Mail registry.  No, this doesn't exist yet.  But obviously it should.  It could be a simple thing like the Do Not Call list:  You put your mailing address on a list, and mass-mailers have to check it before they mail you anything.  Sounds pretty simple to me. 

The only question that remains unanswered is:  Why doesn't this exist yet?  Apparently, there's an organization called the Direct Marketing Association that provides this exact service ... for a $5 fee.  I don't trust anything that charges me money in return for giving my name and address. 

Yes, I visited a similar topic in the recent past:  The National Do Not Spam Registry.  And like that topic, the Do Not Mail list doesn't exist and probably won't exist any time in the near future. #business
