Case Study: Publishers Clearing House achieves higher mobile engagement through personalized, perfectly-timed messaging with Leanplum

Publishers Clearing House increases DAU 30%

Publishers Clearing House (PCH), the long‑standing sweepstakes and direct‑marketing brand, runs several high‑traffic apps downloaded millions of times. As mobile became central to their audience, PCH faced the challenge of keeping users engaged and reducing churn by delivering timely, relevant messages so fans wouldn’t miss sweepstakes, prizes, or new content.

PCH implemented Leanplum’s platform—using A/B testing, analytics and the Optimal Time machine‑learning algorithm—to send personalized messages when individual users were most likely to open them. The targeted lifecycle campaigns drove higher‑than‑expected engagement, improved user experience, yielded new insights into behavior and churn, and ensured users received perfectly timed reminders about sweepstakes and prizes.
