Case Study: Saks Fifth Avenue achieves 10x target ROAS and millions in online revenue with SundaySky SmartVideo Advertising

Saks Fifth Avenue - Customer Case Study

Saks Fifth Avenue, the luxury retail brand and HBC subsidiary, aimed to grow online sales while maintaining a high target return on ad spend (ROAS). The challenge was re-engaging website abandoners quickly and meaningfully within a short conversion window to convert them back into buyers.

Saks partnered with SundaySky to serve personalized, product-focused video retargeting—user-initiated pre-roll ads on publisher sites highlighting designer, category, and product details—to bring shoppers back. The SmartVideo Advertising campaign delivered more than 10× the ROAS target, attributed millions in online revenue, and produced significant lifts in sales, conversions, and brand engagement.
