Case Study: Hansapost achieves 151% higher return on ad spend with Bloomreach Engagement

Exponea’s AI-Driven Lookalike Audiences More Than Double Hansapost’s Return on Ad Spend

Hansapost, Estonia’s largest online retailer, wanted to grow customer acquisition more effectively and partnered with Bloomreach Engagement to test a forward‑looking approach to Facebook lookalike audiences. Bloomreach Engagement used its AI‑driven purchase predictions and Facebook integration to identify customers likely to buy soon and explore whether those signals could seed better prospecting audiences.

Bloomreach Engagement built a 7‑day purchase prediction and ran an A/B campaign: a 20% control group generated a standard lookalike, while an 80% test group was filtered for purchase probability >10% to create a prediction‑driven lookalike for Facebook ads. The Bloomreach Engagement approach delivered clear uplift versus the standard seed audience — +151% revenue, -38% cost per acquisition, +151% ROAS and +62% more purchases.
