Chipotle found strangers who ordered the exact same meal and introduced them by email

Chipotle Rewards had a large, growing base and a massive stream of transaction data, but most loyalty emails were routine. The brand and GALE wanted an email that people would actually want to forward.

They looked for a genuinely improbable coincidence: two complete strangers ordering the same customized burrito, at the same time, in different cities. That is the 'Doppelganger'.

An algorithm found those pairs and sent each a playful email telling them they'd been matched. The surprise — that their exact indulgence was simultaneously someone else's — was the hook, and the oddness made it land on TikTok.

The campaign turned raw purchase history into a socially shareable story, which is far more valuable than a standard CRM blast that no one repeats.
