    increase in customers new to the allergy category

    Driving new sales from existing customers

    An industry-leading pharmacy chain was losing market share in the allergy category. Epsilon’s advanced technology provided new customer insights, enabling personalized messages at the right consideration time, and driving new category sales from existing customers.

    How we did it

    Here's how epsilon used advanced customer insight technology to drive results.

    Analyzing early behavioral signs

    Our machine-learning capabilities analyzed the early behavioral signs of customers who bought in the allergy category before, both online and offline. Based on those contextual insights plus thousands more person-level attributes, we developed a predictive model to recognize existing customers who were ready to enter the allergy category.

    Measuring real impact

    Our transparent in-campaign reporting enabled the pharmacy chain to get proof of performance including the category sales that messaging drove, both online and offline.

    Epsilon’s category driver technology introduced the allergy category to new buyers, resulting in a 5:1 return on ad spend.
