Case Study: Comfrt achieves 12% higher Snapchat iROAS with WorkMagic

How Doubling Snapchat Spend Unlocked 12% Higher ROAS for Comfrt

Comfrt, a fast-growing apparel brand, partnered with the vendor WorkMagic to solve a measurement challenge. The brand needed to understand the true incremental impact of its Snapchat advertising, as last-click attribution was dramatically undervaluing the channel's performance. Comfrt sought clarity on whether Snapchat could scale further without diminishing returns and if it created a halo effect on its TikTok Shop storefront.

WorkMagic implemented a two-phase incrementality testing program to measure Snapchat’s real value. The solution revealed that last-click reporting had been underreporting Snapchat's performance by up to 63%. When Comfrt doubled its ad spend on the platform based on WorkMagic's insights, it achieved a 12% improvement in incremental Return on Ad Spend (iROAS) and identified a significant halo effect driving revenue on TikTok Shop. This led to over $2 million in incremental revenue, allowing Comfrt to confidently scale Snapchat as a core acquisition channel.
