Case Study: US Largest Airlines achieves 20% higher email response and conversion with Mu Sigma's email targeting optimization

Email Marketing Optimization for one of the largest Airlines in the US

Mu Sigma worked with US Largest Airlines, one of the largest airlines in the United States, to improve a marketing program that was sending too many emails and generating low engagement. The airline’s loyalty and CRM teams needed a better email targeting framework to make design-and-execution trigger campaigns and BAU campaigns more relevant to customer behavior and preferences.

Mu Sigma developed an analytical email targeting framework using a test-and-learn approach, evaluating campaign KPIs, audience characteristics, and offer types to improve targeting and measurement. The solution was rolled out across regions and campaign types, helping US Largest Airlines achieve about a 20% increase in response and conversion rates, while also boosting redemption on secondary offers such as hotels and cars.
