Case Study: Shake Shack achieves 184% subscriber growth and 52.7% retention growth with OneSignal

Shake Shack Transforms their Mobile App Experience with OneSignal

Shake Shack, the global fast-casual restaurant chain, needed to modernize its digital customer experience and build a direct, scalable mobile channel to support mobile ordering, delivery, and region-specific promotions. They selected OneSignal for push notifications and in‑app messaging because it offered advanced segmentation, automation, rich media and customizable templates to match Shake Shack’s brand and scale across markets.

OneSignal implemented push and in‑app campaigns, geolocation/radius targeting, engagement-based segmentation and analytics (including branch links to track app-driven sales). The results were rapid and measurable: 2.6M total users, 184% subscriber growth year‑over‑year, and 52.7% customer retention growth; campaign highlights included a Super Bowl in‑app message with ~37k impressions and a 20% CTR and a Milk Bar shake teaser with ~55k impressions and a 52% CTR, alongside clear spikes in coupon redemptions tied to app messages.
