USPS Tactile Sensory Interactive Promotion 2026: How to Save 5-7% on Postage

What Is the USPS TSI Promotion, and Is It Still Available?

The USPS Tactile Sensory Interactive (TSI) promotion was a 2026 postage incentive that gave USPS Marketing Mail letters and flats, and First-Class Mail letters, cards, and flats, a 5% discount when the mail piece carried a USPS-approved specialty ink, sensory treatment, or interactive element. It ran January 1 through June 30, 2026, and stacking the Informed Delivery and Sustainability add-ons brought eligible campaigns to as much as 7% off. That window has closed. Mailers looking for a current discount can use the Continuous Contact, Integrated Technology, or First-Class Mail Advertising promotions plus the two add-ons, and USPS has already posted a 2027 TSI window of January 1 through June 30, 2027. The 2027 discount tiers are published in the USPS guidebook.

This guide breaks down exactly what qualified, how enrollment and the mandatory pre-approval worked, how the add-ons stacked, and where the rules tripped mailers up. Below the recap you will find which USPS promotions remain active for Marketing Mail and First-Class Mail campaigns after the 2026 TSI window closed, plus the 2027 TSI dates USPS has already posted.

How the USPS Tactile Sensory Interactive Promotion 2026 Worked

The USPS Tactile Sensory Interactive promotion 2026 was a postage incentive that gave mailers a 5% discount on qualifying USPS Marketing Mail letters and flats and First-Class Mail letters, cards, and flats when the piece carried a specialty ink, a sensory treatment, or an interactive element. It sat on the USPS 2026 promotions calendar, and USPS built it to reward mailers who pushed past plain print with pieces that reach recipients through special visual effects, sound, scent, texture, or even taste. The 2026 TSI guidebook on PostalPro is the source for every rule recapped here.

"The 5 percent number gets all the attention, but the real story is the offset math. On a large mailing, a 5 percent postage discount typically covers a third to a half of the incremental cost of a specialty finish such as a scratch-off or a soft-touch coating. Add whatever response lift the feature earns, and the finish usually pays for itself on a list that was worth mailing in the first place."

- Cat Boye, Head of Commercial Operations, Mail Processing Associates

The discount was calculated in PostalOne! and applied on the postage statement at the time of mailing; USPS does not rebate it later. The mailer, or its mail service provider, claimed it in the Incentive Claimed section of the electronic postage statement with the two-letter characteristic code SS, and the 5% came off the eligible postage on the spot.

The USPS Tactile Sensory Interactive promotion 2026 was the broadest of the year's promotions because it covered three families of qualifying treatments: specialty inks such as metallic and thermochromic inks, sensory treatments such as embossing, soft-touch coatings, scent, and lenticular or holographic effects, and interactive elements such as scratch-offs, peel-and-reveal panels, pop-ups, and zip strips.

Key Dates and Eligibility at a Glance

The USPS Tactile Sensory Interactive promotion 2026 had firm dates. Mailers who missed enrollment, skipped the written pre-approval, or mailed outside the promotion period forfeited the discount.

Milestone	Date
Registration opens	October 15, 2025
Promotion period begins	January 1, 2026
Promotion period ends	June 30, 2026
Registration closes	June 30, 2026
Discount amount	5% (base)
Maximum stacked discount	7% (with Informed Delivery + Sustainability)
Eligible mail classes	First-Class Mail letters, cards, and flats; USPS Marketing Mail letters and flats; Nonprofit USPS Marketing Mail letters and flats
Where to enroll	Incentive Programs on the USPS Business Customer Gateway (every participating CRID)
Where to submit pre-approval	My Products Portal on the Business Customer Gateway (mandatory; written approval required before the entry date)
Where to claim	Electronic postage statement in PostalOne! (Mail.dat, Mail.XML, or Postal Wizard), characteristic code SS

Eligibility was straightforward: the mailing had to be a USPS Marketing Mail letter or flat (commercial or nonprofit) or a First-Class Mail letter, card, or flat; the piece had to carry at least one qualifying treatment approved in writing by USPS; and the promotion had to be claimed on the electronic postage statement. Periodicals, Bound Printed Matter, and Media Mail were not eligible. Two less obvious rules also applied: the treatment had to sit on the outer envelope or the mailpiece itself, not on an insert, reply envelope, order form, or address label, and any copy that discouraged mail, such as urging recipients to go paperless, made the whole mailing ineligible. USPS calls that mail diversion.

What Qualified as Tactile, Sensory, or Interactive?

This is where most questions came up. The USPS guidebook defined three families of qualifying elements: specialty inks, sensory treatments, and interactive elements. A piece needed at least one, the treatment had to be visible and distinguishable to the recipient and enhance the message, and combining several treatments did not raise the discount past 5%.

Specialty Inks (Visible, Distinguishable Ink Effects)

Inks that soaked into the stock, clear inks, and effects that simply looked like a photo did not qualify.

• Metallic inks, which carry metallic particles that rise to the surface and reflect light
• Optically variable inks that shift with the viewing angle
• Thermochromic (leuco dye) inks that change color with temperature
• Photochromic inks that change under UV light
• Piezochromic and hydrochromic inks that react to pressure or liquid
• Conductive inks that print a circuit to activate a device
• Scented inks, varnishes, and coatings

Sensory Treatments (Texture, Scent, Sound, Visual, Taste)

USPS grouped sensory treatments into five categories, and the treatment had to relate to or enhance the message of the piece.

• Texture: soft-touch or velvet, grit, sandpaper, and leather surfaces, embossing, spot gloss, non-geometric die-cuts, and trailing-edge die-cut envelopes
• Scent: microencapsulated fragrance in a varnish or coating, ambient scented coatings, scented labels, and scratch-and-sniff calls to action
• Sound: paper with an embedded sound chip or speaker
• Visual: holographic treatments (as a sticker, at least 2 by 2 inches and part of the message) and lenticular printing
• Taste: microencapsulated flavors applied in a varnish or coating, the one taste example the guidebook gives

Interactive Elements (The Recipient Physically Manipulates It)

Interactive pieces needed an element the recipient could twist, pull, peel, spin, or bend. Half-folds, tri-folds, gate folds, iron cross folds, and accordion folds did not qualify on their own.

• Scratch-off panels
• Peel-and-reveal panels
• Pop-ups and three-dimensional elements
• Infinite folds that hide layers of content
• Clean-release cards, detached or glued to the piece
• Perforated pull-open zip strips, not at the top of the envelope or on the border

Qualifying Combinations and Edge Cases

The guidebook was specific about what did not count. Gloss stock, laminated postcards, linen-embossed paper, geometric-shaped die-cuts, clear inks, plain stickers, snap packs, tear stubs, and blow-in cards did not qualify on their own, and treatments could not sit in the indicia or barcode clear zones. A flat-printed QR code did not qualify either: USPS defined interactive as something the recipient physically manipulates, and QR-driven shopping, NFC, and augmented reality belong to the separate Integrated Technology Promotion.

How to Stack Add-Ons for Up to 7% Total Discount

The TSI Promotion could stack with the two 2026 USPS add-ons, Informed Delivery and Sustainability, each layering an additional 1% on the 5% TSI base. Add-ons could not be claimed on their own, and up to two could ride on a claimed promotion. Both add-ons run through December 31, 2026, so they still stack on the promotions active after TSI.

Informed Delivery Add-On (+1%)

Mailers who paired an Informed Delivery campaign with their TSI mailing earned an additional 1% discount. Informed Delivery shows subscribers a preview of incoming mail in a daily email or the USPS app, and a mailer can attach a full-color ride-along image with a call to action that links to a target URL.

To qualify, the campaign elements (ride-along image, live target URL, and a representative image of the mailpiece, required for flats) went through pre-approval in the My Products Portal, the mailer enrolled in the add-on through Incentive Programs, the campaign had to be in Submitted or Active status when the postage statement was filed, and the add-on was claimed with the Type A characteristic code PI. USPS also paid an eDoc submitter incentive of 0.5% on pieces that received the add-on; that credit follows whoever files the electronic documentation, usually the mail service provider, so the mail owner's stack tops out at 7%.

Sustainability Add-On (+1%)

The Sustainability Add-On rewarded mailings whose paper came from a certifiable, responsible source. USPS accepted six certifications in 2026: Sustainable Forestry Initiative, Forest Stewardship Council, Programme for the Endorsement of Forest Certification, Bureau Veritas, SCS Global Services, and PrintReleaf. The certificate went in for review through the My Products Portal, the mailer enrolled in the add-on through Incentive Programs, and the 1% was claimed with the Type A characteristic code ST on top of the 5% TSI base.

Maximum Stacked Discount

The USPS Tactile Sensory Interactive promotion 2026 stacked cleanly with the two add-ons. Here is how the math worked 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 $0.467 per piece for Marketing Mail Letter Presort Mixed, a 7% discount works out to roughly $3,300 in savings. On a 500,000-piece campaign at that rate, you are looking at roughly $16,350 saved on postage alone. The premium for a specialty ink, coating, or scratch-off typically runs $0.02 to $0.10 per piece over plain print and is quoted per job, so the discount offsets a meaningful chunk of it, and whatever response lift the feature earns has to cover the rest.

Eligible Mail Classes and Postage Categories

The USPS Tactile Sensory Interactive promotion 2026 applied to USPS Marketing Mail letters and flats (commercial and nonprofit) and to First-Class Mail letters, cards, and flats. Here is the breakdown per the 2026 guidebook.

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 and Cards	Yes	Commercial First-Class Mail
First-Class Mail Flats	Yes	Commercial First-Class Mail
Periodicals	No	Named ineligible in the guidebook
Bound Printed Matter and Media Mail	No	Named ineligible in the guidebook
EDDM (Every Door Direct Mail)	Partly	EDDM Retail was ineligible; EDDM deposited at a Business Mail Entry Unit was an eligible entry method

The discount could be applied to qualifying pieces inside a combined or commingled mailing, but the qualifying mail had to be submitted on its own postage statement or as its own mailpiece version, and only one promotion discount could be applied per mailpiece version.

How Enrollment, Pre-Approval, and Claiming Worked

The discount did not apply automatically. Participation ran in four steps, in order, and USPS runs its other promotions the same way: enroll, get the piece approved, mail inside the window, claim on the statement.

Step 1: Enroll Through Incentive Programs on the Business Customer Gateway

Enrollment ran through the Incentive Programs service on the USPS Business Customer Gateway: select the 2026 Tactile, Sensory, Interactive Promotion and complete the enrollment. It was free, opened October 15, 2025, closed with the promotion on June 30, 2026, and had to be in place before the mailing was finalized (USPS asked for at least two hours of lead time). Every CRID in the by/for fields of the postage statement had to be enrolled before the first mailing that claimed the promotion. If you have never held a permit, the USPS bulk mail permit guide walks through the prerequisites. Postage rates in this guide come from the official USPS Notice 123 rate schedule.

"The enrollment step is where first-time promotion mailers lose the discount before production even starts. Incentive Programs is not hard to use, but every CRID in the by/for of the postage statement has to be enrolled before the mailing is finalized in PostalOne!. We tell every customer to enroll and submit the pre-approval the same week they approve the creative concept, so the USPS reviewer has room to flag anything that would not qualify while there is still time to change it."

- Alec Boye, President, Mail Processing Associates

Step 2: Submit the Mailpiece for Pre-Approval in the My Products Portal (Mandatory)

Pre-approval was not optional in 2026. The guidebook states that participants must upload all mailpiece samples to the My Products Portal for pre-approval, and that a piece not approved in writing before its entry date does not qualify. The mailer, or its mail service provider, opened a service request in the My Products Portal on the Business Customer Gateway, chose Submit Mailpiece Pre-approval, uploaded a PDF of the piece, and mailed a physical sample with the service request printout to the address supplied by the USPS Mailpiece Design Analyst assigned to the ticket. USPS asked for the sample a week before the mail date and committed to a decision within four business days of receiving it, delivered through the portal and by email; some interactive treatments were cleared from the digital submission alone. Samples were never to be emailed.

A prototype could be reviewed if the final piece was not ready, with the final sample submitted once available. Substantial changes after approval meant a new review, USPS audited mailings and could reverse the discount on pieces that did not match the approved sample, and mailers had to keep a hard-copy sample for 90 days after the promotion ended.

Step 3: Mail Within the Promotion Window

USPS defined the window precisely: the mailing had to be finalized in PostalOne! no earlier than 12:00:00 AM Central Time on January 1 and no later than 11:59:59 PM Central Time on June 30, 2026. A mailing finalized on June 29 qualified; one finalized on July 1 did not, even if it was printed in May. Plant-verified drop shipments verified and paid during the window could be accepted at the destination facility up to 15 calendar days after June 30. For any dated promotion, MPA's standing advice is to plan the drop 2 to 3 weeks before the cutoff to absorb production delays, weather, or paperwork hiccups.

Step 4: Claim the Discount on the Electronic Postage Statement

Mailings had to be submitted electronically through Mail.dat, Mail.XML, or Postal Wizard. When the mailing was finalized in PostalOne!, the mail service provider (that is MPA, when we produce the job) claimed the promotion in the Incentive Claimed section with the two-letter characteristic code SS, populating the Component Characteristics Record in a Mail.dat job. PostalOne! calculated the 5% against the eligible postage and showed it on the statement, add-ons were claimed at the same time with their own Type A codes (PI for Informed Delivery, ST for Sustainability), and a promotion not claimed at the time of mailing could not be rebated afterward. Mailers filing their own statements followed the same steps; in Postal Wizard the promotion is a dropdown selection, never applied automatically.

Worked TSI Campaign Examples and Savings

Three modeled scenarios show how the discount math worked across different campaign sizes and feature combinations. They are models, not customer campaigns. Finishing premiums are modeling assumptions (real premiums are quoted per job), and postage is restated at the July 12, 2026 rates now in effect rather than the schedules that applied during the promotion window, so each model reads against today's postage.

Example 1: 50,000-Piece Nonprofit Donor Appeal with Metallic Ink

Take a regional nonprofit's annual appeal letter (#10 envelope, four-color insert) with the envelope teaser line printed in metallic gold ink, a qualifying specialty ink. At 50,000 pieces the math would have looked like this:

Line Item	Amount
Pieces	50,000
Nonprofit Marketing Mail Letter Presort Mixed rate (2026)	$0.257/piece
Total postage before discount	$12,850
TSI 5% discount	-$643
Net postage	$12,208
Assumed metallic ink premium	+$0.04/piece ($2,000)
Net production + postage delta vs. plain	+$1,358

The metallic ink is not free, but donor math is forgiving. For a nonprofit with a $50 average gift and a 4% baseline response rate, even a half-point lift in response means 250 additional gifts, or $12,500, against a net delta of $1,358.

Example 2: 250,000-Piece Healthcare Open Enrollment Campaign with a Soft-Touch Envelope and Informed Delivery

Take a regional healthcare system's open enrollment reminder: 250,000 Marketing Mail letters in a soft-touch coated envelope, a personalized QR code inside linking to the enrollment portal, and an Informed Delivery campaign on the same drop.

Line Item	Amount
Pieces	250,000
Marketing Mail Letter Presort Mixed rate (2026)	$0.467/piece
Total postage before discount	$116,750
TSI 5% discount	-$5,837.50
Informed Delivery add-on 1%	-$1,167.50
Net postage	$109,745
Total savings	$7,005

The soft-touch coating carries the TSI claim in this model. The QR code is there for measurement, not for the discount: a flat-printed code did not qualify as a TSI interactive element in 2026, because USPS required something the recipient physically manipulates, and QR-driven mobile experiences sit under the Integrated Technology Promotion instead. The Informed Delivery campaign adds its 1% and a second touchpoint in the subscriber's inbox. The soft-touch premium is not modeled here because coated envelopes are quoted per job.

Example 3: 100,000-Piece Real Estate Postcard with Scratch-Off

Take a real estate brokerage's 100,000 oversized postcards (6x11) to first-time homebuyers in one metro market. Each postcard carries a scratch-off offering a free home valuation, with a personalized URL revealed under the scratch-off material, and is printed on FSC-certified stock to claim the Sustainability Add-On.

Line Item	Amount
Pieces	100,000
Marketing Mail Letter Presort Mixed rate (2026)	$0.467/piece
Total postage before discount	$46,700
TSI 5% discount	-$2,335
Sustainability add-on (FSC paper)	-$467
Net postage	$43,898
Total savings	$2,802
Assumed scratch-off premium	+$0.06/piece ($6,000)

The TSI discount and the Sustainability Add-On together offset roughly half of the assumed scratch-off premium ($2,802 against $6,000). The response lift from the scratch-off, which varies by market and offer, has to carry the rest.

Common Mistakes That Disqualified TSI Mailings

Most TSI disqualifications came from a small set of preventable errors, and every one of them applies to the promotions still running. The five we saw most often:

1. Skipping enrollment. Production started, the piece looked great, and nobody enrolled the CRID in Incentive Programs. Without enrollment the discount could not be claimed even if everything else was correct.

2. Mailing without a written pre-approval. Every mailpiece had to be uploaded to the My Products Portal and approved in writing before the entry date. A piece that mailed while the request was still open, or changed substantially after approval, lost the discount.

3. Mailing on the wrong side of June 30. Production delays pushed the mail date from late June into early July and the 5% was gone. A 2 to 3 week buffer is the fix.

4. Claiming the wrong characteristic code. SS was the TSI code. Statements that claimed a generic promotion, left the Incentive Claimed section blank, or carried add-on codes without a base promotion did not get the discount.

5. Relying on a feature that did not qualify. Gloss stock, laminated postcards, plain stickers, geometric die-cuts, simple folds, and flat-printed QR codes were assumed to qualify because they looked "specialty." They did not, and copy that urged recipients to go paperless made the whole mailing ineligible. Pre-approval was the only reliable way to confirm before production.

"TSI is a fit when your audience and your product can absorb a few extra cents per piece in finishing. Financial services, healthcare open enrollment, luxury automotive, premium nonprofits, those work beautifully. Where TSI does not pencil out is on commodity verticals running tight margins. If your gross margin per recipient is under 10 dollars, the cost of a scratch-off or a specialty coating eats the discount and then some. We tell customers in those verticals to put the TSI budget into a better mailing list instead, where the lift compounds. In our experience the response lift from a tactile finish shows up in upscale categories and barely registers in commodity ones."

- Cat Boye, Head of Commercial Operations, Mail Processing Associates

Why Direct Mail Production Capabilities Matter for TSI Success

On paper the promotion was simple. In practice the discount was won or lost in execution: a treatment that cleared pre-approval, production that matched the approved sample, data that fed the press and the postage statement correctly, and a postage statement that carried the right code.

MPA runs the mail side of that sequence from one Lakeland, Florida facility. Our direct mail services cover prepress through USPS induction, our two Xerox Iridesse presses print metallic gold, metallic silver, white, and clear in-line with the process colors, and our team manages the variable data, NCOA, and CASS processing behind personalized-URL and QR-code campaigns. We file the postage statements ourselves through PostalOne!, so the promotion code is claimed correctly and the discount applies cleanly. Scratch-off panels, soft-touch and other specialty coatings, embossing, and foil are offered and quoted per job with their own schedule.

For mailers planning a 2027 TSI campaign (USPS has posted a January 1 through June 30, 2027 promotion period, with enrollment opening October 15, 2026), a typical TSI campaign needs 4 to 6 weeks from creative approval to mail drop, factoring in pre-approval, production, fulfillment, and presort. Blocking that lead time on the calendar as soon as enrollment opens is the difference between hitting the discount and missing the cutoff.

Schedule a free consultation to walk through your campaign concept, qualifying features, and timeline. We will tell you up front whether the piece is likely to clear USPS pre-approval, 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 was one of five base promotions on the 2026 USPS calendar: Tactile, Sensory & Interactive (January 1 through June 30, 5%), Catalog Insights (October 1, 2025 through June 30, 2026, 10%), Integrated Technology (5%, any six consecutive months, enrollment through December 31, 2026), Continuous Contact (April 1 through December 31, 2026, 5% on the follow-up mailings in a series), and First-Class Mail Advertising (September 1 through December 31, 2026, 5%), plus the Informed Delivery and Sustainability add-ons that run all year. Each has its own mail classes, feature requirements, and guidebook; our 2026 USPS direct mail promotions guide covers the whole calendar.

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 IMb-tracked campaigns, our intelligent mail barcode guide explains the electronic documentation that every promotion claim rides on.

USPS pays mailers to make mail worth engaging with, and the programs still running keep that offer open: a base promotion plus the two add-ons is worth up to 7% off eligible postage for the rest of 2026. The July 12, 2026 rate change is now in effect, so any discount on a qualifying drop is measured against the current postage schedule. Track upcoming rate-case filings on the USPS PostalPro portal for the latest schedule.

2026 USPS Tactile Sensory Interactive Promotion Recap and What Comes Next

The 2026 USPS Tactile Sensory Interactive promotion window closed on June 30, 2026. Over the six-month run, Marketing Mail and First-Class Mail mailers who added a USPS-approved specialty ink, sensory treatment, or interactive element at production earned a base 5% postage discount, with Informed Delivery and Sustainability add-ons stacking eligible campaigns to as much as 7%.

In our experience the feature earned a lift only when the list and the offer were already sound, and a treatment added purely as a cost play performed like plain print. Treat the discount as a subsidy on creative that was already worth printing, not as a reason to build creative you would not otherwise have mailed.

What replaces the USPS Tactile Sensory Interactive promotion depends on the mail class and the calendar. Marketing Mail mailers looking for a discount window today can use the Continuous Contact Promotion (through December 31, 2026) or the Integrated Technology Promotion (any six consecutive months, enrollment through December 31, 2026); First-Class Mail advertisers can use the First-Class Mail Advertising Promotion (September 1 through December 31, 2026); and the Informed Delivery and Sustainability add-ons stack on any of them. USPS publishes guidebooks for every current program on the PostalPro 2026 Promotions hub and has already posted the 2027 slate, including a Tactile, Sensory & Interactive Promotion that runs January 1 through June 30, 2027 with enrollment from October 15, 2026. The 2027 discount tiers are published in the USPS guidebook. MPA has produced mail for 35+ years across all 50 states, and we help customers pick the right program for their calendar and their concept.
