Case Study: Kolon Mall achieves 15%+ retention lift and 20% lower dormant-user reactivation costs with AppsFlyer Audiences

How Kolon Mall Boosted User Retention with Data-Driven Audience Experimentation

Kolon Mall, a leading fashion eCommerce platform in South Korea, needed to better identify and engage high-value customers from its OLO Club VIP tiers and to reactivate long-dormant users, but lacked a way to scale lookalike audiences and integrate cleanly across partner platforms. To address this, Kolon Mall partnered with AppsFlyer and adopted the AppsFlyer Audiences tool to refine segmentation and campaign targeting.

AppsFlyer ran workshops and helped Kolon Mall create seed audiences from VIP segments, integrate those audiences with platforms like Meta, and scale via lookalike modeling across channels. The implementation took only weeks and delivered measurable impact: retention for users acquired through lookalike campaigns improved by over 15% and the cost to re-engage dormant users dropped by 20%, with ongoing AppsFlyer support helping optimize performance.
