Stack USPS Discounts in 2026: Integrated Technology + Informed Delivery + Sustainability = 7.5% Off Postage

How to combine the 2026 Integrated Technology Promotion (5%) with the Informed Delivery (1% + 0.5%) and Sustainability (1%) add-ons. Stacking rules, eligible mail, and the per-drop math.

8 min read

Most mailers running the USPS 2026 Integrated Technology Promotion stop at the 5% base discount. They miss the stack.

USPS allows up to two add-ons on top of any 2026 promotion. The Integrated Technology Promotion is the one most mailers will qualify for; pairing it with Informed Delivery and Sustainability gets you to 7% on Marketing Mail or 7.5% on eligible First-Class Mail (counting the eDoc-submitter incentive). This is the math, the rules, and the order of operations to stack cleanly.

The stacking rules

USPS publishes these explicitly in the 2026 Add-Ons section:

  • Add-on discounts are added to the promotion discount on eligible mailpieces
  • Add-ons cannot be claimed alone — they require a base promotion
  • You may claim up to two add-ons on a single promotion
  • Mailers who qualify can layer both add-ons
  • Reply Mail IMbA is not eligible for any add-ons

The two add-ons available in 2026:

Add-onDiscountBonus
Informed Delivery1%0.5% eDoc-submitter incentive (separate, see below)
Sustainability1%—

The maximum stacked discount: 5% (promotion) + 1% (Informed Delivery) + 1% (Sustainability) = 7%, plus the 0.5% eDoc incentive on the postage-statement submitter side.

The math on a real drop

A 100,000-piece First-Class postcard drop at 2026 rates (roughly $0.48 per piece for automation letters/cards) costs about $48,000 in postage.

Layer-by-layer savings:

Discount levelSavings on $48,000Mailer cumulative
5% Integrated Technology only$2,400$2,400
+ 1% Informed Delivery$480$2,880
+ 0.5% eDoc submitter$240$3,120
+ 1% Sustainability$480$3,600

Total per drop: $3,600. Run six monthly drops over a 6-month promotion window: $21,600 in postage savings for adding a QR code, an Informed Delivery campaign, and a sustainability certification to mail you were going to drop anyway.

(The eDoc incentive technically goes to the postage statement submitter. If you submit your own eDocs through a Mail Service Provider, the math depends on which party captures the 0.5%. For agencies running mail on behalf of clients, it’s typically split in the operating agreement.)

Stacking rule #1: pick your promotion first

The 5% Integrated Technology Promotion is the base. The add-ons attach to it on the postage statement. Step zero is qualifying for the base promotion — which means using one of the eight eligible technologies (AR, MR, VR, Voice Assistant, Video in Print, NFC, Mobile Shopping, or AI) with proper directional copy, pre-approval, and registration on the Business Customer Gateway.

The pillar guide covers the qualification rules end-to-end. For most teams, the AI track is the easiest path; the QR-code-triggered Mobile Shopping path is the second easiest.

Stacking rule #2: add Informed Delivery

The Informed Delivery add-on requires building an Informed Delivery campaign — an email-based digital companion that USPS sends to recipients who’ve signed up for Informed Delivery alerts. Per USPS, average open rate is 58.6%, a meaningful complementary channel to the physical drop.

What an Informed Delivery campaign needs:

  • Ride-Along Image — 300×200px full-color image with a CTA. Appears in the recipient’s daily digest email. Required.
  • Representative Image of the Mailpiece — 780×500px max color image of what’s coming. Required for flat-sized mailpieces, optional for letters.
  • URL — live, working, mobile-optimized target. Required.

Eligible mail for the Informed Delivery add-on (note this is narrower than the base Integrated Technology Promotion):

  • First-Class Mail automation letters, postcards, and flats
  • USPS Marketing Mail automation letters and flats
  • USPS Marketing Mail DDU-entered Carrier Route Saturation Flats
  • Nonprofit USPS Marketing Mail automation letters and flats
  • Nonprofit USPS Marketing Mail DDU-entered Carrier Route Saturation Flats

Submit the Informed Delivery campaign via USPS’s campaign portal at least 2 hours before your mail date. Common submission errors (per USPS, ~80% of failures):

  1. Campaign in draft status when the postage statement is filed — must be Submitted or Active
  2. Postage Statement mailing dates fall outside the Informed Delivery campaign timeline

On the postage statement, the Informed Delivery add-on uses CCR characteristic code PI.

Stacking rule #3: add Sustainability

The Sustainability add-on requires demonstrating that the paper used in the mailing is responsibly sourced. USPS accepts seven proof points:

  1. Sustainable Forestry Initiative (SFI) certification
  2. Forest Stewardship Council (FSC) certification
  3. Programme for the Endorsement of Forest Certification (PEFC)
  4. Bureau Veritas certification
  5. SCS Global Services certification
  6. PrintReleaf (carbon-offset paper tracking)
  7. Submit a Certificate for Review with a URL (a catch-all for other recognized standards)

Most commercial printers already have at least one of these certifications. If yours doesn’t, ask — many run FSC chain-of-custody and don’t market it.

Eligible mail for the Sustainability add-on (also narrower than the base):

  • First-Class Mail letters, cards, and flats
  • USPS Marketing Mail letters and flats
  • Nonprofit USPS Marketing Mail letters and flats

CCR characteristic code on the postage statement: ST.

Stacking rule #4: register everything before mailing

The order of operations:

  1. Pre-approve the mailpiece via My Products Portal (Integrated Technology submission)
  2. Register the CRID for the Integrated Technology Promotion via Business Customer Gateway → Incentive Programs
  3. Register the CRID for the Informed Delivery add-on (separate registration on the same portal)
  4. Register the CRID for the Sustainability add-on (separate registration)
  5. Submit the Informed Delivery campaign with Ride-Along, URL, and Representative Image
  6. Mail the piece during your 6-consecutive-month window
  7. File the postage statement electronically with CCR codes IT + PI + ST

All three registrations must happen at least 2 hours before the mailing’s postage statement is submitted. The mail owner CRID identified in the by/for of the postage statement must be enrolled for each.

There is no auto-enrollment. If a CRID isn’t on the eligibility list, the discount doesn’t apply.

What’s NOT stackable

A few clarifications:

  • Only one promotion discount per mailpiece. You can’t claim Integrated Technology + Tactile/Sensory/Interactive on the same piece. Pick one base promotion.
  • Multiple qualifying technologies don’t compound. A mailpiece with AR + QR + AI still earns one 5%.
  • Multiple add-ons cap at two. Even if a future USPS year adds more, two is the maximum stack.
  • Reply Mail IMbA is excluded from add-ons (but eligible for base promotions).

The realistic ceiling

For most mailers, the path to 7% off postage in 2026 is:

  1. Use AI to draft mailpiece copy (qualifies for Integrated Technology, 5%)
  2. Add a QR code as a technology trigger on the same piece (still one 5%; doesn’t compound but reinforces eligibility under multiple technology categories)
  3. Set up an Informed Delivery campaign with Ride-Along, URL, and matching mailpiece image (+1%)
  4. Print on FSC-certified paper (most commercial printers offer this — confirm with your printer) (+1%)

For First-Class mailers who submit their own eDocs through a registered permit, add the 0.5% eDoc-submitter incentive for 7.5% total.

What this looks like across the 2026 promotion calendar

The Integrated Technology Promotion has a flexible 6-consecutive-month window inside calendar 2026. The Informed Delivery and Sustainability add-ons run January 1 – December 31, 2026 with no window restriction beyond the base promotion’s.

Practical implication: if your 6-month base-promotion window is July 1 – December 31, the add-ons attach to every qualifying mailing inside that window. They don’t extend the window; they multiply it.

What we recommend

For 2026 mailers building out their promotion stack:

  1. Pick the AI or Mobile Shopping technology track. Lowest barrier to entry, easiest pre-approval.
  2. Register all three (promotion + 2 add-ons) at the same time. One pass through the Business Customer Gateway, one set of CRID enrollments.
  3. Build a single Informed Delivery campaign template that adapts per drop. Ride-Along image with version-specific creative; URL with UTM params.
  4. Confirm your printer’s sustainability certification. Ask them for the certificate ID and PDF. If they don’t have one, switch to a vendor who does — or use PrintReleaf for retroactive carbon offset on existing print.
  5. Submit pre-approval at least 3 weeks before mail date. USPS reviews in 4 business days; revisions extend.
  6. Use CCR codes IT, PI, ST on the postage statement. Don’t forget any of them — claiming only base IT leaves the add-on discounts on the table.

The DirectMail.io platform handles all three registrations, the Informed Delivery campaign uploads, and the CCR codes on the postage statement as part of the standard postal stack.
