What Is a Business Reply Mail Envelope?
A Business Reply Mail Envelope (BRE) is a pre-addressed, postage-paid envelope that lets your recipient respond without applying a stamp. You—the sender—only pay for postage if and when the envelope is returned.
It’s the ultimate frictionless response mechanism, ideal for campaigns where fast, easy replies matter most.
Benefits of Using a Business Reply Mail Envelope:
- Removes Friction: No stamps = no excuses
- Boosts Response Rates: Especially for fundraising, surveys, or lead capture
- Only Pay for Results: You’re billed for returned mail, not the entire list
- Professional & Trustworthy: BREs signal that your brand means business
Courtesy Reply Envelopes
Postalytics also supports Courtesy Reply Envelopes (CREs)—another reply option that includes a pre-addressed envelope but requires the recipient to provide their own postage.
CREs are ideal for engaged audiences, such as loyal customers, donors, or members, where response is more likely and you want to keep costs low.
Benefits of Using a Courtesy Reply Envelope:
- Lower Cost: You don’t pay for unused returns
- Simple to Set Up: No USPS permit required
- Great for High-Intent Audiences: Perfect for renewals, reactivations, and more
BRE vs. CRE: What’s the Difference?
Here’s a side-by-side comparison to help you decide which reply envelope is best for your next direct mail campaign:
Feature | Business Reply Envelope (BRE) | Courtesy Reply Envelope (CRE) |
Postage Paid By | You (sender), only if returned | Recipient (adds their own stamp) |
USPS Permit Required | Yes – Business Reply Permit | No permit required |
Ease of Response | Very high – no stamp needed | Moderate – postage must be added |
Available in Postalytics | All letter formats | Only with 8.5×14 format & perforated return slip |
Best Use Cases | Cold leads, donations, surveys, bill pay, financial forms | Loyal customers, renewals, event RSVPs, budget-conscious mail |
TL;DR:
- Use a BRE when high response rates are critical and you want to remove friction.
- Use a CRE when mailing to people who already trust you—and you want to save on cost.
Both BREs and CREs Available in Postalytics—Here’s How to Choose
Postalytics is now one of the only direct mail automation platforms to offer both BRE and CRE support—fully integrated into your campaign builder.
That means you can:
- Build smart, automated campaigns using either or both reply options
- Segment by audience and offer the right envelope to the right group
- Track mail delivery and response just like a digital channel
You don’t have to choose one or the other. With Postalytics, you can use both—strategically.

How to Use a Courtesy Reply Envelope in Postalytics
CREs are even easier to set up—no USPS permit needed.
Here’s how:

- Choose the perforation option to include a tear-off return slip
- The option to include a #9 Courtesy Reply Envelope will automatically appear
- Customize it with your return address
- Purchase CRE credits in advance or during campaign setup
CREs are only available with the 8.5×14 Letter format, and are ideal for donation forms, membership renewals, or reply slips.
Best Practices for Using Reply Envelopes in Direct Mail
Here’s how to get the most from both BREs and CREs:
Campaign Goal | Recommended Envelope | Why It Works |
Cold audience lead generation | Business Reply Envelope (BRE) | Reduces friction; maximizes response |
Nonprofit fundraising appeal | BRE or CRE (test both) | Match envelope to donor type and frequency |
Payment or invoice return | BRE | Easy remittance process for customers |
Subscription renewal | CRE | Lower cost; high-intent audience |
Survey or feedback collection | BRE | Boosts returns with no-cost barrier |
Event RSVP | CRE | Engaged audience likely to respond with postage |
Pro Tip: Run an A/B test with both envelope types to see what drives higher ROI for your audience segments.
Why Business Reply Mail Envelopes Are a Game-Changer
In traditional direct mail, reply rates often come down to friction and cost. Asking someone to respond AND pay for postage can tank performance—especially in acquisition or first-touch campaigns.
BREs solve that by letting you:
- Track delivery and response inside your CRM or marketing automation
- Only pay for results—you’re not wasting postage
- Seamlessly include reply functionality inside an automated direct mail campaign
That’s Postalytics: making direct mail as smart, fast, and data-driven as digital.
