Case Study: Global Healthcare & Pharmaceutical Company achieves 36% email re-engagement and boosts customer LTV with Treasure Data

Global Life Sciences Leader Revitalizes Customer Engagement to Maximize Customers’ LTV

A global life sciences and pharmaceutical leader faced a permanent shift to remote engagement—87% of healthcare professionals now prefer all-virtual or hybrid meetings—so the company needed to improve performance of cost-effective digital channels (email and web) and ensure sales reps reached HCPs with the right content at the right time. Existing systems were costly, inflexible, and lacked the data unification and automation required to maximize customer lifetime value while maintaining strict security and privacy controls.

The company deployed Treasure Data Customer Data Cloud to unify customer data, perform ID resolution, and integrate with marketing automation and recommendation engines. That enabled automated, personalized topic recommendations and timed follow-up reminders for sales reps, plus targeted awareness campaigns—driving a 22% lift in email open rates, a 36% increase in re-engagement, 3M+ personalized topic suggestions delivered to ~2K reps, 173K+ HCPs engaged, and improved ROI and consent-compliant data security.
