It also has information on other opt-out services, such as the National Do Not Call Registry and the Direct Marketing Association's mail and e-mail opt-out lists.
There is also catalogchoice.org, a National Wildlife Federation-sponsored site to opt-out of receiving catalogs. For this one, you create an account and register all the catalogs that you receive, and they contact them on your behalf to cancel them. Not as magical as the other ones, but still useful.
In summary, here are the following links and what they opt you out of:
|National Do Not Call Registry||Unsolicited sales phone calls|
|www.optoutprescreen.com||Pre-approved credit card offers|
|DMA Mailing List||Mailed marketing offers|
|DMA Email List List||Emailed marketing offers|
