Does Return to Sender Stop Junk Mail?

When USPS allows you to refuse mail

The current USPS Domestic Mail Manual says an addressee can refuse a piece when it is offered for delivery. After delivery, the addressee may mark it “Refused” and return it within a reasonable time if the piece and its attachments remain unopened.

There are exceptions. Registered Mail, insured mail, Certified Mail, collect-on-delivery pieces, Adult Signature mail, and certain response mail cannot be returned postage-free under that rule.

Opening the piece changes the rule

USPS Customer Support Ruling PS-177 explains that a delivered piece cannot be opened and then refused without new return postage. A sender's “Return Service Requested” endorsement does not preserve free return service after the recipient opens the piece.

If you need the mailing label to make an opt-out request, you can photograph the outside without opening an envelope that is not addressed to you.

Why Return to Sender may never reach the advertiser

USPS explains that undeliverable Marketing Mail without an ancillary service endorsement is disposed of rather than returned. The phrases “Return Service Requested,” “Address Service Requested,” and similar endorsements are instructions printed by the mailer. Writing your own phrase on an unendorsed advertisement does not create that paid service.

Even when a piece is returned, that physical return is not the same as a documented request to suppress the name and address from future campaigns.

Use the mailing label to stop future pieces

1. Identify the sender. Find the company name, website, return address, or customer-service information on the piece.
2. Copy the label exactly. Keep the recipient name, delivery address, and any customer or source number.
3. Ask for postal marketing removal. Contact the sender through its official mailing-preference, privacy, or customer-service channel.
4. Keep the request date. Mail already prepared can still arrive after a list is changed.

For mail addressed to someone else

Do not open mail addressed only to another person. Separate advertising from bills, government notices, financial documents, and personal correspondence. For a former resident's catalog or promotional postcard, tell the sender that the named person no longer lives at the address. Our previous-resident guide walks through that request without impersonating them.
