General Mills boosts ROAS 203% with Stackline

General Mills, a major food company, faced the challenge of creating a meaningful and measurable sustainability campaign for Earth Month. They needed to translate cause-based messaging into quantifiable ROI, reach shoppers across media formats, and efficiently allocate their budget. To overcome this, they partnered with vendor Stackline and its Atlas platform for unified audience management and omnichannel measurement.

Stackline implemented a full-funnel media strategy powered by its AMC intelligence. The solution involved a sequenced campaign on Fire TV, Amazon DSP, and Sponsored Ads that connected storytelling with purchase intent. Through Stackline's tools and professional services, the campaign was optimized in real-time, resulting in a 203% increase in ROAS and a 47% boost in sales, making it General Mills' highest-grossing Amazon sales week.
