Unsolicited mail—also called junk mail, bulk mail, or direct mail advertising—fills millions of mailboxes across the United States every day. The average American household receives approximately 41 pounds of junk mail annually, according to the Environmental Protection Agency. This includes credit card offers, product advertisements, catalogs, newsletters, and promotional materials you never asked to receive.

Unsolicited mail exists because companies and organizations purchase mailing lists to reach potential customers. These lists come from many sources: previous purchases you've made, warranty cards you've filled out, online forms you've submitted, public records like voter registration and property ownership, and data brokers who collect information about consumers. When you provide your address to any business—even for legitimate purposes—it may end up sold to marketing companies.
Different types of unsolicited mail serve different purposes. Credit card offers arrive because credit card companies buy lists of people matching their target customer profile. Catalogs come from retailers hoping you'll browse and order. Charitable solicitations arrive from nonprofits seeking donations. Political mail increases dramatically during election seasons. Many pieces of unsolicited mail contain personalized elements—your name, address, or account numbers—making them feel targeted even though they're sent to thousands or millions of people.
Understanding how unsolicited mail flows into your mailbox is the first step toward controlling it. The mail doesn't stop on its own, but you have several legitimate methods to reduce the volume. Some methods work immediately, while others take weeks or months to show results because marketing companies operate on cycles and the mail system itself has delays built into it.
Practical Takeaway: Keep records of where you provide your address. Limiting who has your information reduces how often your address appears on mailing lists.
The Mail Preference Service (MPS) is a program operated by the Data & Marketing Association, a trade organization representing the direct mail industry. When you register with MPS, your name and address are added to a "do not mail" list that member companies consult before sending unsolicited mail. Registration is free and requires no fees, subscriptions, or personal information beyond your name and address.

To register with MPS, you have two options. The first is online at dmachoice.com. You create an account, enter your name and address, and select your preferences for the types of mail you want to reduce. Options include declining credit card and financial offers, catalogs, magazines, and nonprofit solicitations. The online process takes about 10 minutes. The second option is by mail: you can print a form from the website or request one by calling 1-888-5-OPTOUT (1-888-567-8688). Fill out the form and mail it to the address provided. Processing by mail takes 3 to 12 weeks.
When you register, your information goes into a database that direct mailers use during their sending process. However, MPS is not legally binding. Companies are not required by law to check the database—they do so voluntarily. This means registration with MPS reduces unsolicited mail but does not eliminate it completely. Studies suggest MPS registration reduces mail volume by roughly 50 percent, though results vary by household and by how many marketers comply with the list.
Registration lasts five years. After five years, your registration expires and mail volume may increase again, so you'll need to re-register if you want to continue. The system also has limitations: it works mainly for general advertising mail, not for mail from organizations you've previously done business with, financial institutions where you have accounts, and some government mail.
Practical Takeaway: Register at dmachoice.com for the fastest results, but plan to re-register every five years to maintain reduced mail volume.
Credit card offers represent a significant portion of unsolicited mail for many households. You may receive multiple pre-approved credit card offers each month, even if you've never requested one. These offers come because credit card companies purchase lists of consumers matching their lending criteria, often based on credit scores and financial history obtained from credit bureaus.

There is a specific, legally established method to stop these offers: contacting the credit reporting agencies that provide lists to credit card companies. Under federal law, credit reporting agencies must maintain an opt-out system for pre-screened credit card and insurance offers. You can opt out by calling 1-888-5-OPTOUT (1-888-567-8688) or visiting optoutprescreen.com. When you call, you hear a menu where you select whether to opt out for five years or permanently. The call takes a few minutes. Online, you complete a form with your name, address, phone number, and date of birth. You can choose five-year or permanent opt-out.
Opting out through the official system works because the major credit reporting agencies—Equifax, Experian, and TransUnion—are required by law to honor your request and tell credit card companies not to send pre-screened offers to your address. Results typically appear within 30 days of opting out. However, this process stops offers based on pre-screening; it does not stop all credit card mail. You may still receive offers from credit card companies if you've had a relationship with that company previously or if they obtain your address through other means.
For additional control, you can also contact individual credit card companies and banks where you have accounts and request removal from their marketing lists. Most financial institutions have customer service phone lines where you can request to be removed from promotional mailings. Some have online account settings where you can manage marketing preferences. Keeping track of these contacts helps you document your efforts to reduce mail.
Practical Takeaway: Call 1-888-567-8688 to opt out of pre-screened credit card offers. This single call affects all three major credit reporting agencies and produces results within 30 days.
Catalogs and retail promotional mail arrive because you've made purchases from retailers, visited their stores, or provided your address during transactions. Department stores, clothing retailers, specialty shops, and online merchants all maintain mailing lists and send catalogs and advertisements to past customers. According to the Catalog Association, millions of catalogs arrive in American mailboxes monthly, representing both paper waste and mailbox clutter for recipients.

To reduce catalog mail, you can contact retailers directly. Most major retailers have customer service departments and websites with mail preference options. When you contact a retailer, you can request removal from their mailing list. Some retailers allow you to manage mailing preferences through your online account. For example, if you have an account with a clothing retailer's website, you may find a "communication preferences" or "marketing preferences" section where you can opt out of catalogs. Calling the customer service number on your account statement or the back of a catalog and speaking with a representative is another direct method.
There are also third-party services that help reduce catalog mail. CatalogChoice.com is a free website where you can list catalogs you receive and request removal. You enter the catalog name and your information, and the service contacts the catalog company on your behalf. The company says it has processed millions of opt-out requests since its founding. Another option is DMAchoice.com, which includes catalog preferences when you register with the Mail Preference Service mentioned earlier.
Results from catalog removal requests vary in timing. Some retailers remove your address within days, while others take several weeks. Because new catalogs are planned and produced months in advance, you may continue receiving catalogs even after requesting removal—they were already in production when your request arrived. Multiple requests to the same company may be necessary. Keeping a list of catalogs you've requested removal from helps you track progress and identify which companies comply quickly and which do not.
Practical Takeaway: Visit CatalogChoice.com and register catalogs you receive to reduce them through one website, rather than contacting each retailer individually.
Charitable solicitations—requests for donations from nonprofits, religious organizations, and advocacy groups—represent another major category of unsolicited mail. These organizations maintain donor lists and mailing lists of prospects, and they exchange names with other organizations. If you've ever donated to a charity or made a purchase supporting a cause, your name likely appears on multiple charitable mailing lists. Political mail also falls into this category and increases significantly during election years.
