Case Study: ChristianaCare achieves 4x higher response rates with Strata Company

ChristianaCare Achieves 4x Higher Response Rates with Advanced Personalization

ChristianaCare, a Mid-Atlantic health system, faced diminishing returns from a long-running two-touch new-mover campaign that used one-size-fits-all creative. To personalize at scale without changing the campaign’s proven structure, ChristianaCare partnered with Strata Company to apply advanced personalization and data-driven targeting to better match messaging to demographics, geographies, and patient needs.

Strata Company redesigned the outreach into an 18-version program—six tailored first impressions and twelve follow-ups—driven by demographic and geographic segmentation, consistent branding, and a branded First Aid Kit incentive. The personalized approach lifted response rates from 1.3% to 5.6% (roughly 4x), increased engagement from 2.8% to 13.2%, and grew referral requests from 245 to 761 (about triple), and ChristianaCare has extended the program to continue scaling these gains with Strata Company.
