Case breakdown
THE PROMO MECHANIC, THE RECEIPT PROOF, THE PAYBACK.
Every campaign runs on the same consumer promotion platform: a promo mechanic people want, receipt validation that blocks fraud, and first-party consumer data that ties spend to real buys.
The problem: budget out, no proof back
Doritos wanted new fans, not just sales. A classic price promo brings deal seekers, not first-time triers.
The mechanic: cashback and receipt validation doing the work
- Weekend 100% cashback at a single retailer via WhatsApp.
- Onboarding into the brand's direct-messaging list at redemption.
- Post-purchase survey to measure trial and repeat intent.
The payback: real buys, named buyers, measured ROI
Most redeemers had never tried Doritos. Almost all said they would buy again. The chips paid for themselves. The fans came free.
The takeaway. One promo euro can buy a sale, a receipt, a review and a named buyer at the same time. That is promotion attribution you can hand to anyone in the room.
