Las Vegas, NV – January 2026 — This year at CES, Microsoft Advertising, Publicis Media Exchange (PMX) and Epsilon announced that Epsilon data is now available on the Microsoft Advertising Platform, unlocking a new era of precision targeting for Publicis Media clients.

The collaboration, Third-Party Search (3PS), brings together Microsoft’s advertising reach, Epsilon’s industry-leading identity and data, and PMX’s strategic activation expertise to deliver a new, first-of-its-kind approach to audience solutions that outperform traditional targeting models. By leveraging Epsilon’s rich consumer insights within Microsoft’s ecosystem, advertisers can now engage high-value audiences across search, native, and display with unprecedented accuracy and scale.

Early Success: In pilot in the travel vertical, the partnership is already proving its impact. In a recent pilot with a client in the travel vertical, campaigns powered by Epsilon delivered:

2X higher ROAS compared to traditional in-market audiences
42% net-new targetable audience, converting travelers not previously identified through other first-party audiences
Significant efficiency gains and bookings, validating the power of integrated data and identity-driven targeting.
