Interstitial Pages &
SMS Coupon Delivery:
Opt-In, Deliver, Build Your List
An interstitial page is a mobile-optimized opt-in screen that sits between a QR scan or SmartLink click and the SMS conversation — presenting your offer, capturing consent, and delivering the coupon via MMS in one seamless flow. No forms. No app downloads. One tap.
Interstitial pages and SMS coupon delivery are the same feature — the interstitial IS the coupon delivery mechanism. Understanding how they work together is the key to setting them up correctly in TextingOnly.
What Is an Interstitial Page?
An interstitial page is a purpose-built mobile screen that appears when a contact taps a SmartLink or scans a QR code — before the SMS conversation begins. It shows your offer (the coupon, the discount, the event registration), a clear CTA, and routes the contact into their native SMS app with one tap.
Unlike a standard landing page with navigation, forms, and multiple CTAs, an interstitial has one job: get the contact to tap Send in their Messages app. Everything else is stripped away. This is why interstitial opt-in rates (71%) dramatically outperform web forms (19%).
The interstitial page does NOT deliver the coupon. It presents the offer and routes the contact into SMS. OTTO delivers the coupon via MMS the moment the contact taps Send. The interstitial is the offer. The SMS is the delivery.
The Complete Flow — Step by Step
Setting Up a Coupon Delivery Flow
Coupon images for MMS delivery should be JPG or PNG, under 600KB, and sized around 600×400px for consistent rendering across carriers. Very large files can delay delivery or be rejected by some carriers. If your coupon design file is large, compress it before uploading to the collector’s Final Message.
Configuring the Interstitial Page
Interstitial pages in TextingOnly are built directly in the dashboard — no code required. Key configuration options:
The main value proposition — “Get 20% Off Your Next Visit” or “Claim Your Free Appetizer.” This is the first thing the contact reads. Make it specific and time-relevant.
1–2 lines of supporting detail — expiry, restrictions, how to redeem. Keep it short. The interstitial is not a landing page — long copy kills conversion.
Action-oriented and value-focused: “Get My Coupon,” “Claim 20% Off,” “Text to Save.” Avoid generic labels like “Click Here” or “Submit.”
Change the offer, headline, or CTA in the dashboard at any time — without reprinting QR codes. The QR code destination is dynamic. Update the interstitial and the next scan sees the new offer.
Self-Segmentation Interstitials
Beyond simple coupon delivery, interstitial pages can be used for self-segmentation — presenting the contact with a choice before routing them into different OTTO flows. For example:
Self-segmentation interstitials let contacts qualify themselves before OTTO engages — routing a “Sales” contact to a lead qualification flow and a “Service” contact to an appointment booking flow, all from the same QR code placement.
Per-Placement Attribution
Create a separate QR code or SmartLink for each physical or digital placement. Table tent, receipt, window cling, social post, and email CTA should each have their own — tracked separately in your reports. You’ll see which placement drove the most scans, highest opt-in rate, and most coupon redemptions.
For businesses with multiple locations, create a separate QR code per location. Your coupon report will show which location drives the most engagement and which placements within each location perform best — so you know where to concentrate print spend.
The full coupon strategy — 71% opt-in rate, 98% open rate, how every redemption simultaneously builds your re-marketable SMS list.
