Case Study: Jumbo achieves a 158% lift in conversions and $500K in new revenue with Amplitude Recommend

How Jumbo Interactive Delivers Spotify-like Personalization for Every User

Jumbo Interactive, operator of Oz Lotteries, faced low conversion rates from broad, untargeted marketing—relying on mass emails and lacking the baseline data to understand customer behavior. The company needed a way to personalize experiences that felt inviting rather than intrusive while respecting privacy, so it could increase engagement and sales across its web and app channels.

Jumbo implemented Amplitude Recommend alongside Braze and FullStory to build behavior-based cohorts and deliver AI-driven recommendations via email, push, and on-site content cards. The solution went live in weeks and drove clear gains: a 158% lift in conversions on one checkout page, an estimated $500K in new annual revenue opportunity, and test improvements of +20% for email, +32% for app push, and +8.5% for content cards.
