Case Study: Radio Free Europe achieves a 35% increase in opt-ins with OneSignal

Radio Free Europe’s Opt-In Rate Jumps 35% After Implementing OneSignal

Radio Free Europe (RFE/RL), the U.S. government-funded broadcaster reaching 38 million users across 22 countries, needed to modernize digital engagement after a custom Web Push SDK proved time- and resource-intensive and produced internal errors. To avoid further engineering drain, Radio Free Europe adopted OneSignal’s engagement platform and SDK for push notifications and in‑app messaging.

OneSignal’s SDK enabled automatic language detection, audience segmentation, tag-variable substitution, and localized in‑app messages so RFE could deliver personalized, cross-channel notifications. After implementing OneSignal, Radio Free Europe saw opt-ins rise 35%, average click-through rates reach about 2.5%, and user app retention improve (15% overall, with in‑app messaging delivering up to a 27% lift).
