Case Study: Fastic GmbH achieves 30% more subscriptions and 15% monthly revenue from re-engagement with MoEngage

Fastic, A Health & Fitness App With 50+ Million Downloads, Successfully Migrates to MoEngage

Fastic, the world's largest fasting app with more than 50 million downloads, struggled with limited analytics, fragmented reporting and slow support while using Iterable. Needing a scalable customer engagement platform to handle over 100 million emails and 12 million daily reachable users, sophisticated journeys and faster iteration, Fastic migrated to MoEngage’s insights‑led Customer Engagement Platform.

MoEngage’s team migrated 100 campaigns and 30+ complex journey flows in three weeks and deployed solutions like Email Builder, AI Recommendation Sherpa, Journey Orchestration and MoEngage Analytics to power personalization and milestone “Happy Moment” engagement. The outcome: re‑engagement now generates 15% of monthly revenue, over 30% of re‑engaged users convert to subscribers, subscription purchases rose ~30%, average email open rates hit 40%, and CAC declined significantly — all delivered through MoEngage.
