The Postal Service delivers 17.8 tons of bulk mail each year, 44% of which goes unopened, according to the EPA. Just 22% of bulk mail is recycled. To stop the flow, visit the Direct Marketing Association, the leading global trade association of business and nonprofit organizations using and supporting multichannel direct marketing tools and techniques, at www.dmachoice.org, and get put on the "do not mail" list. It costs one dollar, but it'll remove your name from the lists for five years.

DMA offers DMAchoice which is free for online users. For those who would prefer to register for DMAchoice via mail, there is a $1 processing fee. For more information visit www.dmachoice.org.

Also visit optoutprescreen.com, an official Consumer Credit Reporting Industry site, to opt out of receiving credit card and insurance offers. It's free.
