Direct mail works. But what if you could make it work even better—and cost less?
Direct mail remains one of the most effective, high-quality marketing solutions you can choose. For many marketers, the biggest disadvantage to direct mail is how quickly costs can add up.
How to reduce direct mail postage costs? The USPS First-Class Mail Advertising Promotion offers a discount program that gives incentives when using first-class mail: a 5% postage discount on marketing materials that already deliver faster delivery times and higher engagement rates than standard mail. If you're serious about maximizing direct mail ROI, this promotion deserves a spot in your 2026 marketing calendar.
Think fall and holiday season promotions
The key requirement for the discount: Your mail piece must include advertising or marketing content and be sent First-Class during the Q4, September 1–December 31, 2026 promotional window. Registration deadline is July 15-December 31.
The details are here—and EMCO can help you take full advantage.
What Is the First-Class Mail Advertising Promotion?
The First-Class Mail Advertising Promotion offers a 5% discount on postage for marketing and advertising content targeted for September through December delivery. Unlike Marketing Mail (formerly Standard Mail), First-Class Mail delivers faster, generates higher open rates, and signals quality to recipients.
Promotion Details:
Discount: 5% on postage
Eligibility: First-Class Mail letters, cards, and flats featuring advertisements or marketing messages
Promotion Period: September 1 – December 31, 2026
Registration Period: July 15 – December 31, 2026
When to Use This Promotion
The September – December timing makes this promotion ideal for a variety of industries and messaging:
Holiday marketing campaigns (Black Friday, Cyber Monday, holiday shopping)
Year-end sales and promotions (Retail, Business to Consumer/Business to Business)
Q4 product launches
Year-end fundraising appeals (non-profits)
Tax planning services (financial services, banking)
Event promotion (organization conferences, community events and gatherings)
First-Class Mail vs Marketing Mail
First-class mail offers distinct advantages over marketing mail that can significantly boost campaign performance:
Faster Delivery — First-Class Mail typically delivers in 1-3 business days compared to 3-10 days for Marketing Mail. Speed matters when promoting limited-time offers, events, or seasonal campaigns.
Higher Engagement Rates — Recipients perceive First-class mail as more important. It looks and feels like personal correspondence, not bulk advertising—which translates to higher open rates and better response.
Forwarding & Return Service — First-class mail is automatically forwarded if recipients have moved and returned to sender if undeliverable. Marketing Mail gets discarded. This keeps your mailing list clean and ensures your message reaches the right person.
Premium Perception — Using First-class mail signals that your message matters. It's the difference between "just another flyer" and "something worth opening."
What Qualifies for the Discount?
Examples of First-Class Mail Pieces Eligible for USPS Promotions
Postcards – 3.5" × 5" to 4.25" × 6", up to 1 oz
Letters (in envelopes) – up to 6.125" × 11.5", up to 3.5 oz
Personalized marketing letters – mailed as letter-size First-Class pieces
Invoices, statements, and notices – typically letter-size, up to 3.5 oz
Small booklets or brochures in envelopes – First-Class flats, up to 13 oz, max 12" × 15"
More Ways to Maximize USPS Discounts: Add-ons
USPS Informed Delivery Add-On (+1%) — Integrate your mail piece with USPS Informed Delivery, which gives recipients a digital preview of their incoming mail via email or mobile app. This creates an omnichannel touchpoint before the physical piece arrives. Use the eDoc Postage Statement Submitter tool for an additional 0.5% incentive.
Sustainability Add-On (+1%) — Demonstrate that your paper is responsibly sourced sustainable direct mail exhibiting an eligible certification (FSC, SFI, PEFC, or similar). Show your commitment to environmental responsibility while cutting costs.
Total potential savings: Up to 7% on postage when combining the First-Class Mail Advertising Promotion with both add-ons.
