Case Study: MyPostcard achieves 318% increase in user signups with Leanplum

MyPostcard Increases User Signups by 318% with Leanplum

MyPostcard, a Berlin-based mobile app founded in 2014 that lets users create and send personalized postcards to over a million people worldwide, faced the need to improve conversions, boost retention, and better understand user behavior. Their initial marketing solution lacked integrated analytics, A/B testing, and deep personalization, so they sought a reliable all‑in‑one partner to optimize the entire customer journey.

By adopting Leanplum as their multi‑channel marketing platform, MyPostcard used integrated analytics, A/B testing, personalization, and lifecycle campaigns to continuously test and optimize onboarding and checkout experiences. The result: signups grew by up to 318% for some user groups, customer referrals rose 51%, and user value at key checkout points increased by 16%, alongside faster setup and ongoing optimization.
