Those envelopes marked "No Postage Necessary if Mailed in the United States" represent a real financial commitment. Under USPS regulations, companies holding a Business Reply Mail permit guarantee payment of First-Class postage plus a per-piece fee on every envelope returned to them.[6]
How Business Reply Mail Works
- The company pays only when the envelope is physically returned — nothing if you discard it
- Typical cost to them: $0.70–$1.20 per returned envelope [6]
- The envelope must be used for its intended purpose under USPS regulations
- You can return it completely empty — it still costs them
- Stuffing it with the sender's own materials stays within normal weight limits
Legal boundary: USPS regulations require BRM envelopes to be used for their "intended purpose." Taping heavy objects to them violates postal regulations and may result in the piece being discarded as non-mailable.[6] The right move: stuff it with the junk they sent you and include a written opt-out request.
The Right Way — Step by Step
- Find the prepaid BRM envelope in the mailer (marked "No Postage Necessary" or "Business Reply Mail")
- Remove or black out any personal information you don't want to return
- Fold the rest of the junk mail they sent and place it inside
- Add a written note: "Please permanently remove me from your mailing list" and your mailing label
- Seal it and drop in any USPS mailbox — they pay on delivery
Including a written opt-out request with your mailing label significantly increases the chance the company processes your removal. You're filing an opt-out AND costing them money simultaneously — maximum efficiency. Use our Letter Generator to create one in seconds.
The "Return to Sender" Myth
Writing "Return to Sender" on a piece of marketing mail does NOT route it back to the sender. USPS only returns mail carrying specific endorsements — "Address Service Requested," "Return Service Requested," or similar. Most bulk marketing mail carries no such marking and will simply be discarded by USPS.[6]
Will This Actually Stop the Mail?
Returning the envelope alone does not guarantee removal. But combining the return with a written opt-out request is genuinely effective — companies pay attention when the same address keeps sending their envelopes back. For permanent large-scale results, pair this with the opt-out methods in our How to Stop Junk Mail guide.
