“As a healthcare brand in a highly regulated industry, we have to be stringent with the opportunities we choose to test and learn from. Undertone’s new SORT cookie-less targeting solution was a welcome solution to our Open Enrollment campaign as it allowed a privacy-compliant way to test moving away from traditional 3rd party and pixel-based targeting and optimization models. 
Through SORT, Undertone identified and optimized toward top-performing SmartGroups throughout the flight, driving a 39% and 87% lift across our core creative units, as compared to cookie-based methods. As our industry moves away from cookies, solutions like SORT ensure that we are future-proofing Ambetter by maximizing campaign KPIs in a compliant, consumer-first way”.
