Epsilon

Epsilon is a marketing services agency that is part of the Publicis Groupe, one of the world’s largest advertising and public relations firms. Apart from providing typical marketing consulting services, the firm also has a marketing cloud for personalizing customer journeys with omnichannel marketing automation capabilities as well as a consumer data platform (CDP) that can integrate with other marketing automation platforms. A key feature of its CDP platform is its “Core ID” feature, which is a customer identity solution that does not depend on third-party cookies. This provides users with visibility into more than 200 million US consumers while adhering to privacy standards.

In April 2021, Epsilon partnered with Trade Desk (a media buying platform and data management platform) to join its Core ID system to “Unified ID 2.0,” an industry-wide initiative to create an alternative to third-party cookies.
