Case Study: Retail Powerhouse improves campaign performance with Tredence's global holdout solution

Implementing Global Holdout in Marketing Campaigns for a Retailer Catering to 90M Households

Retail Powerhouse, a leading global retailer serving about 90 million households and engaging more than 8 million customers daily across online and offline channels, struggled to accurately attribute marketing impact across millions of dollars in monthly campaigns. Overlapping audiences, inconsistent test-and-learn setups, limited orchestration across teams, and an overreliance on short-term KPIs made it difficult to measure true incrementality and long-term customer value.

Tredence implemented a scalable marketing measurement ecosystem built around a global holdout and an Azure Databricks-powered marketing Datamart to isolate campaign effects, improve attribution, and track both short- and long-term customer behavior. The solution enabled closed-loop measurement and better campaign optimization, delivering measurable gains including a 1–2% improvement in campaign performance, a 2–3% increase in engagement rates, and about a 3% uplift in conversion rates.
