What Is the USPS Tactile Sensory Interactive Promotion 2026?
The USPS Tactile Sensory Interactive promotion 2026 is a postage incentive program that gives mailers a 5% discount on qualifying USPS Marketing Mail letters and flats when those mail pieces include physical, sensory, or interactive enhancements. The program is part of the broader USPS 2026 Promotions and Incentive Programs slate, and it's designed to reward mailers who push beyond plain print and create pieces that engage recipients through touch, sight, sound, smell, or direct interaction.
The discount applies at the time of mailing, not as a rebate later. When you submit your mailing through PostalOne! or PostalWizard, you select the characteristic code "SS - Tactile, Sensory, Interactive" and the system applies the 5% off your eligible postage. No invoicing games, no waiting for credits.
The USPS Tactile Sensory Interactive promotion 2026 is the most flexible of this year's USPS promotions because it covers a wide range of qualifying features -- from foil stamping and embossing to QR codes, scratch-off panels, and scented inks. That breadth means most marketers can find a way to qualify without overhauling their creative concept.

| Milestone | Date |
|---|---|
| Registration opens | October 15, 2025 |
| Promotion period begins | January 1, 2026 |
| Promotion period ends | June 30, 2026 |

Eligibility is straightforward: the mailing must be a USPS Marketing Mail letter or flat (commercial or nonprofit), the promotion characteristic must be selected on the postage statement, and the mail piece must include at least one qualifying TSI feature. First-Class Mail, periodicals, and packages are not eligible for this specific promotion. If you're mailing First-Class statements or transactional pieces, look at other 2026 USPS promotions instead.
What Qualifies as Tactile, Sensory, or Interactive?
This is where most questions come up. USPS defines four broad categories of qualifying enhancements, and your mail piece needs at least one to qualify. You can use multiple features, but the discount stays at 5% total -- adding more TSI features doesn't increase the base discount. Here's the breakdown.
Tactile Enhancements (You Can Feel It)
Tactile features change the physical texture or finish of the mail piece. The recipient should be able to feel something different from a standard printed surface.
- Foil stamping (cold foil, hot foil, or digital foil)
- Embossing or debossing (raised or recessed elements)
- Specialty coatings: soft-touch, sandpaper, leather-feel, suede coatings
- Spot UV coating with raised effects
- Die-cuts that change the silhouette of the piece
- Specialty paper stocks with distinct textures (linen, felt, kraft, cotton)
- Glitter or beaded inks
- Thermography (raised printing using heat-cured powder)
Sensory Enhancements (You Can Smell or See It Differently)
Sensory features engage senses beyond touch -- typically smell or sight beyond standard print.
- Scented inks or coatings (scratch-and-sniff or ambient)
- Color-changing inks (thermochromic, photochromic)
- Lenticular printing (image changes as you tilt the piece)
- Glow-in-the-dark inks
- Holographic elements or holographic foil
Interactive Enhancements (You Do Something With It)
Interactive features require the recipient to physically engage with the piece -- pulling, scratching, scanning, or assembling.
- Scratch-offs revealing offers, codes, or messages
- QR codes linking to landing pages, videos, or AR experiences
- Augmented reality (AR) triggers
- Near-field communication (NFC) chips embedded in the piece
- Pop-ups or fold-out elements
- Pull-tabs, peel-and-reveal panels, or punch-outs
- Built-in sound chips
- Origami-style folds that reveal hidden content
Qualifying Combinations and Edge Cases
The USPS guidebook is specific about what counts and what doesn't. A QR code printed flat on the mail piece qualifies as interactive. A standard glossy UV coating does not qualify by itself -- it has to be specialty UV (textured, raised, or unusual). A mail piece printed entirely on matte cardstock with no other features doesn't qualify, even if the stock feels different from gloss.
When in doubt, the test is whether the feature meaningfully changes how the recipient experiences the mail piece versus a standard 100# gloss postcard. Foil stamping passes. Aqueous coating fails. Scratch-off passes. Spot varnish on its own usually fails.
How to Stack Add-Ons for Up to 7% Total Discount
The TSI Promotion can stack with two of the 2026 USPS Add-On programs. Each add-on layers an additional 1% on top of the 5% TSI base.
Informed Delivery Add-On (+1%)
Mailers who include an Informed Delivery campaign with their TSI mailing can earn an additional 1% discount. Informed Delivery shows recipients a grayscale scan of incoming mail in their email or USPS app -- you can submit a color "ride-along" creative that replaces the gray scan with a branded image and click-through link. For commercial mailers, this turns a single piece into a digital touchpoint plus a physical one.
To qualify, you submit the Informed Delivery campaign through the Informed Delivery Mailer Campaign Portal, link it to your mail job, and select the appropriate characteristic on the postage statement. The campaign must be active during the mailing window.
Sustainability Add-On (+1%)
The Sustainability Add-On rewards mailings that meet specific environmental criteria. Eligible criteria include using FSC-certified or recycled paper stock, applying a USPS-recognized sustainability statement on the mail piece, or meeting other documented environmental standards published in the 2026 sustainability guidebook. The 1% adds on top of the 5% TSI base when criteria are met and properly claimed.
Maximum Stacked Discount
The USPS Tactile Sensory Interactive promotion 2026 stacks cleanly with two add-ons. Here's how the math works at full stack:
| Component | Discount |
|---|---|
| TSI Promotion base | 5.0% |
| Informed Delivery Add-On | +1.0% |
| Sustainability Add-On | +1.0% |
| Maximum total | 7.0% |
For a 100,000-piece Marketing Mail letter campaign at the 2026 commercial rate of around $0.43 per piece, a 7% discount works out to roughly $3,010 in savings. On a 500,000-piece campaign, you're looking at $15,050 saved on postage alone. That's not the whole story -- the production costs of TSI features (foil, scratch-offs, specialty coatings) typically run $0.02-$0.10 per piece more than plain print -- but the discount offsets a meaningful chunk of that, and the response-rate lift from sensory mail typically more than covers the rest.
Eligible Mail Classes and Postage Categories
The USPS Tactile Sensory Interactive promotion 2026 applies to USPS Marketing Mail letters and flats (both commercial and nonprofit rates). Here's what is and isn't eligible at a glance.
| Mail Class | Eligible? | Notes |
|---|---|---|
| USPS Marketing Mail Letters | Yes | Commercial automation rates |
| USPS Marketing Mail Flats | Yes | Commercial automation rates |
| Nonprofit Marketing Mail Letters | Yes | Nonprofit automation rates |
| Nonprofit Marketing Mail Flats | Yes | Nonprofit automation rates |
| First-Class Mail Letters | No | Look at other 2026 promotions |
| First-Class Mail Flats | No | Not eligible for TSI |
| Periodicals | No | Not eligible for TSI |
| Packages / Parcel Select | No | Not eligible for TSI |
| EDDM (Every Door Direct Mail) | Generally no | EDDM Retail does not qualify; check guidebook for EDDM-BMEU eligibility |
If your campaign mixes eligible and ineligible classes (say, an EDDM saturation drop plus an addressed Marketing Mail follow-up), you can claim the TSI discount only on the addressed Marketing Mail portion -- assuming it meets all other requirements.
How to Register and Claim the Discount
The discount doesn't apply automatically. There's a four-step sequence to participate, and each step has to happen in order.
Step 1: Register in the Mailing Promotions Portal
Log in to the USPS Business Customer Gateway and access the Mailing Promotions Portal. Select the 2026 Tactile, Sensory & Interactive Promotion and complete the enrollment form. Registration is free, but it has to be completed before you submit your mailing -- ideally several weeks ahead of your mail date.
You'll need your USPS-assigned customer registration ID (CRID), your mailer ID (MID), and contact information for the responsible party. If you've never run a USPS promotion before, the USPS bulk mail permit guide walks through the prerequisites.
Step 2: Submit a Sample for Pre-Approval (Recommended)
USPS strongly recommends submitting a sample mail piece for pre-approval before production. The Mail Piece Approval Process (MPA) gives you a written confirmation that your piece qualifies before you commit to printing 100,000 copies. Without pre-approval, you risk producing a campaign that gets disqualified at the postage statement stage -- which means paying full postage on the entire job.
Samples can be physical mock-ups, full prototypes, or digital files showing the qualifying feature with documentation. The USPS team typically returns approval decisions within 5-10 business days.
Step 3: Print and Mail Within the Promotion Window
The mail piece must be printed and physically tendered to USPS between January 1 and June 30, 2026. Mailings dropped on June 29 still qualify. Mailings dropped on July 1 do not, even if production happened in May.
For most clients, MPA recommends planning the mail drop at least 2-3 weeks before the June 30 cutoff to absorb any production delays, weather issues, or paperwork hiccups. Cutting it close to the deadline is how mailings end up being mailed on July 2 and losing the discount.
Step 4: Claim the Discount on the Postage Statement
When the mailing is finalized in PostalOne! or PostalWizard, the Mail Service Provider (MSP) -- that's MPA, if we're producing the job -- selects the "SS" characteristic code on the Statement of Mailing (PS Form 3602). The 5% discount calculates against the eligible postage and shows up as a line-item credit on the statement. If Informed Delivery or Sustainability add-ons apply, those characteristic codes are selected as well.
If you're handling your own mailing through a PostalOne! account, the same workflow applies. The characteristic codes are dropdown selections on the statement -- they're not auto-applied based on the mail piece itself.
Real-World TSI Campaign Examples and Savings
A few representative scenarios show how the discount math plays out across different campaign sizes and feature combinations.
Example 1: 50,000-Piece Nonprofit Donor Appeal with Foil Stamping
A regional nonprofit sends an annual appeal letter (#10 envelope, four-color insert) and adds gold foil stamping to the envelope teaser line. The campaign runs in February 2026.
| Line Item | Amount |
|---|---|
| Pieces | 50,000 |
| Nonprofit Marketing Mail letter rate (2026) | $0.234/piece |
| Total postage before discount | $11,700 |
| TSI 5% discount | -$585 |
| Net postage | $11,115 |
| Foil stamping production cost | +$0.04/piece ($2,000) |
| Net production + postage delta vs. plain | +$1,415 |
The foil isn't free, but a typical donor appeal seeing a 1-2% lift in response rate from a more premium-feeling piece usually returns multiples of the production delta. For a nonprofit with $50 average gift size and a 4% response rate baseline, even a 0.5% lift means an additional 250 gifts -- $12,500 in incremental revenue.
Example 2: 250,000-Piece Healthcare Open Enrollment Campaign with QR Codes and Informed Delivery
A regional healthcare system runs an open enrollment reminder via Marketing Mail flats with a personalized QR code linking to the enrollment portal. They also submit an Informed Delivery campaign for the same drop.
| Line Item | Amount |
|---|---|
| Pieces | 250,000 |
| Marketing Mail flat rate (2026, automation) | $0.395/piece |
| Total postage before discount | $98,750 |
| TSI 5% discount | -$4,937.50 |
| Informed Delivery add-on 1% | -$987.50 |
| Net postage | $92,825 |
| Total savings | $5,925 |
The QR code adds essentially zero production cost (it's part of the variable data layer), and Informed Delivery campaign setup is a one-time fee in the low hundreds of dollars. This is the cleanest version of TSI savings -- features that already make the campaign more measurable, with the discount as a bonus.
Example 3: 100,000-Piece Real Estate Postcard with Scratch-Off
A real estate brokerage mails 100,000 oversized postcards (6x11) to first-time homebuyers in the Tampa Bay region. Each postcard includes a scratch-off offering a free home valuation, with a personalized URL revealed under the scratch-off material.
| Line Item | Amount |
|---|---|
| Pieces | 100,000 |
| Marketing Mail letter rate (2026) | $0.43/piece |
| Total postage before discount | $43,000 |
| TSI 5% discount | -$2,150 |
| Sustainability add-on (FSC paper) | -$430 |
| Net postage | $40,420 |
| Total savings | $2,580 |
| Scratch-off production cost | +$0.06/piece ($6,000) |
The scratch-off raises the response rate substantially in a region where direct mail to homebuyers is competitive. The TSI discount and sustainability add-on offset roughly a third of the production cost premium, and the sensory differentiation typically lifts response 15-30% over plain printed cards.
Common Mistakes That Disqualify TSI Mailings
Most TSI disqualifications come from a small set of preventable errors. The five we see most often:
1. Missing the registration deadline. Production starts, the piece looks great, and someone forgets to register the mailing in the Promotions Portal. Without registration, the discount can't be claimed even if everything else is correct. Register before producing, not after.
2. Mailing on the wrong side of June 30. Production delays push the mail date from late June into early July. The 5% is gone. Build in a 2-3 week buffer.
3. Selecting the wrong characteristic code on the postage statement. "SS" is the TSI code. Mailers sometimes select "Marketing" or "Promotion" generically without specifying TSI, and the discount doesn't apply. Confirm the code with the MSP or the PostalOne! help desk before finalizing.
4. Using a feature that doesn't actually qualify. Aqueous coating, standard gloss UV, and basic gloss laminate often get assumed to qualify because they're "specialty." They don't. Pre-approval through the MPA process is the easiest way to confirm before production.
5. Mixing ineligible mail classes into a "promoted" mailing. First-Class pieces, periodicals, and parcels can't claim TSI even if they're co-mailed with eligible Marketing Mail. Split the mailings or accept that only the Marketing Mail portion gets the discount.
Why Direct Mail Production Capabilities Matter for TSI Success
The USPS Tactile Sensory Interactive promotion 2026 sounds straightforward on paper, but execution is where most campaigns either capture the savings or lose them. The mail piece has to be designed for the qualifying feature, the production has to deliver consistent quality across hundreds of thousands of pieces, the data and addressing has to feed correctly into both the printing equipment and the postage statement, and the paperwork has to flow through PostalOne! without errors.
MPA handles all five steps from one Lakeland, Florida facility. Our direct mail services cover design consultation through USPS induction, our Xerox Iridesse 6-color digital press handles foil simulation and specialty inks at production speed, and our in-house data team manages the variable data, NCOA, and CASS processing that drives QR-code and personalized-URL campaigns. We handle the postage statement filings ourselves through PostalOne!, so the TSI characteristic code gets selected correctly and the discount applies cleanly.
For mailers who want to take advantage of the 2026 promotion before June 30, the planning window is closing. A typical TSI campaign needs 4-6 weeks from creative approval to mail drop -- factoring in pre-approval, production, fulfillment, and presort. Starting now means a mail drop in mid-to-late June, which leaves margin against the cutoff.
Schedule a free consultation to walk through your campaign concept, qualifying features, and timeline. We'll tell you up front whether the piece qualifies, what the production options look like, and where the discount math lands for your volume.
Beyond TSI: How This Fits With Other 2026 USPS Promotions
The TSI Promotion is one of several 2026 USPS incentive programs. The full slate includes the Tactile, Sensory & Interactive Promotion (this one), the Informed Delivery Promotion, the Continuous Contact Promotion, the First-Class Mail Advertising Promotion, the Reply Mail IMbA Promotion, the Sustainability Add-On, and the Mobile Shopping Promotion. Each has different qualifying mail classes, different feature requirements, and different discount levels.
For a comprehensive view of the 2026 postage landscape and how rates connect to these promotions, see our 2026 USPS postage rates breakdown. For mailers running heavy IMb-tracked campaigns, our intelligent mail barcode guide explains how IMb-related promotions stack with TSI in some cases.
The big picture: 2026 is a year where USPS is actively trying to retain Marketing Mail volume, and the promotions reflect that. Mailers who plan around them can offset most of the year's rate increase with a combination of TSI, Informed Delivery, and Sustainability discounts. Mailers who don't plan around them are paying full rate when 5-7% off is available.
Frequently Asked Questions
When does the USPS Tactile Sensory Interactive promotion 2026 start and end? +
The USPS Tactile Sensory Interactive promotion 2026 runs from January 1, 2026 through June 30, 2026. Mail pieces must be tendered to USPS within that window to receive the 5% discount. Registration is open from October 15, 2025 through June 30, 2026. The promotion is active right now, and there are roughly seven weeks remaining as of early May 2026.
How much can I save with the USPS TSI Promotion? +
The base discount is 5% off eligible postage on USPS Marketing Mail letters and flats (commercial or nonprofit rates). You can stack the Informed Delivery Add-On (+1%) and the Sustainability Add-On (+1%) for a maximum 7% total discount. On a 100,000-piece Marketing Mail letter campaign at the 2026 commercial rate of $0.43/piece, that's roughly $3,010 saved at full stack.
What kinds of features qualify for the TSI Promotion? +
Qualifying features fall into three buckets. Tactile features include foil stamping, embossing, debossing, specialty coatings (soft-touch, sandpaper), die-cuts, and textured papers. Sensory features include scented inks, color-changing inks, lenticular printing, and holographic elements. Interactive features include QR codes, scratch-offs, augmented reality triggers, NFC chips, pop-ups, and pull-tabs. Standard gloss UV coating, aqueous coating, and plain matte stock do not qualify on their own.
Can I stack the TSI discount with other USPS promotions? +
You can stack TSI with two specific add-ons: the Informed Delivery Add-On (+1%) and the Sustainability Add-On (+1%). You cannot stack TSI with other 2026 base promotions like Continuous Contact or First-Class Mail Advertising on the same mail piece -- you pick one base promotion per mailing.
Does EDDM qualify for the TSI Promotion? +
EDDM Retail does not qualify for the TSI Promotion. EDDM-BMEU may qualify in certain circumstances but the rules are specific and limited -- check the 2026 TSI guidebook or pre-clear with USPS before assuming eligibility. For most mailers, TSI is best applied to addressed Marketing Mail rather than EDDM.
Do I need to register before printing my mail piece? +
Yes. Registration through the Mailing Promotions Portal must happen before the mailing is submitted to USPS. We recommend registering and submitting a sample for pre-approval at least 4-6 weeks before the planned mail date so production has time to adjust if anything needs to change.
Who fills out the postage statement to claim the discount? +
Your Mail Service Provider (MSP) typically files the postage statement through PostalOne! or PostalWizard and selects the "SS" characteristic code that triggers the 5% TSI discount. If you're filing your own postage statement directly, you select the code yourself. Either way, the code has to be selected on PS Form 3602 -- the discount isn't automatic.
What happens if my mail piece is disqualified after production? +
If USPS rejects the TSI claim at the postage statement stage, you pay full postage on the eligible portion of the mailing -- losing the 5%. This is why pre-approval matters: the MPA process gives you written confirmation before production that the piece qualifies. Skipping pre-approval means betting the discount on USPS's interpretation at the time of mailing.
Can a nonprofit claim the TSI discount? +
Yes. Nonprofit Marketing Mail letters and flats are eligible at the same 5% discount applied to nonprofit automation rates. The savings are smaller in absolute terms (because nonprofit rates are already lower) but the percentage is the same.
How does MPA help with TSI campaigns? +
MPA handles the full TSI workflow from one facility: feature consultation, mail piece design review, pre-approval submission, production (foil, embossing, scratch-offs, specialty coatings, variable data QR codes), data processing, postage statement filing, and USPS induction. We've run promotional discount mailings since the program started, and we know which features pre-approve cleanly versus which ones get pushback.
