BRM stands for Business Reply Mail — a USPS service that lets companies pre-pay for return postage on envelopes they include in their mailings.[1] You've seen these hundreds of times: the envelope printed with "No Postage Necessary if Mailed in the United States" and a distinctive permit imprint in the upper right corner instead of a stamp.
The key mechanic: the company pays nothing when they print it. They only pay when you drop it in a mailbox and USPS delivers it back to them. Every envelope you return costs them real money — typically $0.70 to $1.20 per piece, including First-Class postage plus a per-piece handling fee.[1]
How to Identify a BRM Envelope
Look for these markings on the envelope's front face:
- "NO POSTAGE NECESSARY IF MAILED IN THE UNITED STATES" printed in the upper right area
- A permit imprint box (usually reads "BUSINESS REPLY MAIL" or "FIRST-CLASS MAIL PERMIT NO. XXXX")
- Horizontal FIM (Facing Identification Mark) bars — a small row of vertical bars near the top edge
- The company's return address pre-printed on the envelope
- A POSTNET or Intelligent Mail barcode along the bottom
Not all prepaid return envelopes are BRM. Some are "Courtesy Reply Mail" (CRM) — these have a stamp area and require you to add postage. Only BRM envelopes with the "No Postage Necessary" imprint are truly prepaid at the sender's expense.
How the USPS BRM Permit System Works
To use BRM, a company must hold a valid USPS Business Reply Mail permit for the post office that will receive the returned mail. They pay an annual permit fee to USPS, then pay per piece only when envelopes are physically returned and delivered.[1]
- Annual permit fee: paid upfront regardless of volume
- Per-piece charge: First-Class postage rate + handling surcharge (~$0.21–$0.30 extra per piece)
- Accounting method: companies can prepay a deposit or be billed monthly
- Volume discounts exist for high-volume permit holders
This structure means a mailer sending 100,000 pieces assumes they'll only get a small fraction returned. Every additional return you send raises their cost-per-acquisition — making their campaigns measurably less profitable.
What You Can Legally Do With a BRM Envelope
USPS regulations require that BRM envelopes be used for their "intended purpose" — that is, as return mail for the piece they came with.[2] Within that framework, you have real options:
- Mail it back completely empty — it still costs them the full per-piece fee
- Stuff it with the junk mail they sent you — stays within normal weight limits
- Include a written opt-out request with your name and mailing label
- Add a printed opt-out letter generated by our Letter Generator
Legal boundary: Adding heavy objects, bricks, or anything outside the original mailing violates USPS regulations on BRM usage and may result in the piece being treated as non-mailable or returned to you.[2] The effective and legal approach is stuffing it with the sender's own materials and a written opt-out — same financial impact, no postal violations.
Using BRM as an Opt-Out Tool
Returning the envelope alone does not guarantee opt-out processing — many companies require a specific written request linked to your mailing label. The combination that works: return the BRM envelope with the original junk mail folded inside, plus a written opt-out note or letter that includes your full name and mailing address as it appears on the label.
Generate Your Opt-Out Letter
Create a formatted opt-out demand letter in seconds. Professional, Stern, or Maximum Spite — your choice. Print it, fold it, stuff it in the BRM envelope.
When There's No BRM Envelope
Some junk mail — particularly from smaller local businesses, political campaigns, or non-profit solicitations — doesn't include a BRM envelope. In that case you have two options: ignore it, or send them a letter yourself.
If you want to send a physical opt-out demand letter without printing it yourself, our Send a Letter tool lets you enter the company's address and we'll have a formatted letter printed and mailed via USPS First-Class mail for $3.99 — covering print, envelope, and postage through Lob.
Does Returning BRM Mail Actually Stop It?
On its own, returning one envelope rarely triggers immediate removal. What it does do is register a direct opt-out signal at the company — more effective than ignoring the mail, and far more effective than writing "Return to Sender" (which does not work for bulk mail without specific USPS endorsements).
For lasting results, combine the BRM return with upstream opt-outs: OptOutPrescreen.com for credit card and insurance offers, DMAchoice.org for general marketing mail, and data broker removal for the databases that keep re-selling your address.
Incogni removes you from 180+ data broker databases — the upstream source that keeps re-selling your address to new mailers — automatically, every quarter.
