We received this information from Erik Anderson a few months ago:
http://www.stopjunkmailkit.com.
This site sells a kit that gives you step-by-step directions on how to stop most of the junk mail you get. The kit is sold for $17.50 directly on the site.
As a thank you to subscribers, the organization will plant 3 trees for every kit sold.
Thanks Erik!
I checked into some other sites like this.
http://www.greendimes.com/ has a similar program.
You can also go http://earth911.org/georgia/land/reducing-your-junk-mail/
Here you can get street addresses to send requests via snail mail to be removed from additional databases.
Just don’t complain to me when your client wants to do a direct mail campaign or some research and there aren’t any lists to buy.
