You can save yourself a few bucks and boost your chances of reducing junk mail altogether by contacting companies yourself. It may not sound simple, but launching one well-orchestrated attack can stop junk mailers for good.

It's this easy: Sit down at the computer and devise a form letter stating in clear language that you want to be removed from a company's list. Be sure to include your correct and complete name, address, and signature. Then, fill in the company names, print, and send your letter to:

List Brokers

These companies sell names, addresses, and profiles of people likely to respond to mail solicitations. Send your form letter to The Polk Company, Donnelley Marketing, Database America, and List Services. If you run a business, include Dun & Bradstreet.

"Dear Occupant" Coupon Distributors

The largest are ADVO Inc., Cox Target Media, Harte-Hanks Data Services, and Money Mailer.

Credit Bureaus

Credit bureaus sell your financial information (along with your name; address; date of birth; Social Security number; employer's name and address; and your payment history on loans, credit cards, and other bills). Calling the National Opt-Out Center will stop the three major bureaus— Experian, Equifax, and Trans Union— from sharing your specifics.

Catalogs, Charities, And Professional Associations

Contact these companies via their toll-free numbers to stop unwanted mail. Tell them not to write or call you every month to let you know your membership is going to expire well down the road. A one-month notice is sufficient.

Government Agencies

Ask the county clerk, department of motor vehicles, and voter registration office to keep your information confidential.
