From the blog of Tim Ferriss (author of the 4-Hour Work-week), some advice about getting removed from mailing lists.
…get removed from junk mail lists and common commercial mailing lists. There are a few ways to do this: 1) Get remove from the most common junkmail lists (this costs a few dollars in some cases) and check alternative strategies at www.stopjunkmail.org, 2) Use LifeLock, or another identity protection service, which automatically removes you from large mailing lists, one of the most common vehicles for identity theft. Last, we’ll have your mail forwarded to special processing centers, where it is all scanned and emailed to you. One popular service is called Remote Control Mail, and there are two big benefits to the time-focused and mobile-minded: relevant postal mail is funneled into e-mail, so you can check both email and postal mail at once (“batching” both at the same time); you can travel freely whenever and wherever without ever missing a letter.
