Case Study: Queenly reduces CPI by 40% with AppsFlyer

Reducing CPI by 40% after eliminating performance blindspots

Queenly, a North American shopping marketplace for formalwear, needed a better way to measure performance across five paid media partners and owned channels like email, organic social, SMS, and its website. Before AppsFlyer, the team was working with incomplete data from individual channels and could not send email users directly into the app, limiting how well it could evaluate true campaign impact.

Using AppsFlyer’s measurement suite, mobile attribution, and deep linking/customer experiences tools, Queenly unified cross-channel measurement and routed email traffic directly to the app. With AppsFlyer’s holistic data, Queenly shifted budget to better-performing campaigns and reduced cost per install by 40%, while also optimizing email based on in-app purchases rather than just open and click-through rates.
