Test, Learn, Grow: How an Insurer Ditched Direct Mail Orthodoxy to Win Younger Members
A century-old North American insurer used Darwin to safely experiment with TV and digital video — proving upper-funnel investment drives lower-funnel efficiency and delivering 7% member growth in under a year.
Client: North American Insurance Company

Problem
A century-old North American insurer had built its marketing around direct mail but its customer base was aging. Attracting younger demographics meant embracing TV, social, search, and digital video, a significant cultural shift for an organization with deeply entrenched channel habits. The risk: investing in unfamiliar channels without knowing what would actually drive new quote requests and member sign-ups.
Solution
The company deployed Darwin to analyze conversion attribution across channels, identify high-ROI opportunities, and model investment scenarios with and without budget restrictions. This enabled a structured Test & Learn approach for faster learning from experiments with less capital at risk.
Insight
Direct mail was losing its edge — despite remaining the single largest contributor to conversions, direct mail was no longer cost-effective compared to newer channels
TV and digital video offered better incremental returns — data showed these channels delivered stronger ROI on incremental investment, justifying a meaningful budget shift
Upper funnel drives lower funnel efficiency — the data demonstrated that brand-building activity in TV and digital video improved the performance of acquisition tactics downstream, not just awareness
Results
7% growth in new memberships
24% increase in quote requests
TV advertising budget increased 68%
