- 1). Call the customer service department of any company sending you unwanted mail. Most letters will have a contact number printed in small type on the bottom or the back side of the page. On reaching a company representative, request that your name and address be removed from the mailing list. Companies are obligated to stop sending you mail once the request is made. However, it might take a few months before the unwanted letters stop.
- 2). Unsubscribe via email. Whether receiving spam email or in hard items through the mail, you can remove yourself from a mailing list electronically. In much the same as the customer service phone number, an email address or website address will be provided by the company. Follow any links and provide your email address and home address, if necessary. After making the stop request, it might take a few months for the unwanted mail to stop.
- 3). Register with Direct Marketing Association (DMA). The DMA is an online tool developed to help consumers control the mail they receive. When you register, you are able to decide the type of commercial mail that is sent to you. You may choose to receive no unsolicited mail or only those pieces that interest you. This means that after some time the mail you receive will reflect your interests.
