Decades of data-driven marketing expertise

We’ve spent over 50 years helping brands turn data into lasting relationships. When marketing lived in the mailbox, we were the first to address individuals by name.

That principle continues to guide our evolution across data, technology and digital media, powering marketing that learns and adapts over time.

Trusted by the world's leading brands

Today, Epsilon operates across six continents helping brands build stronger connections with real people. Recognised by organisations such as IDC, Forrester and the MRC, Epsilon continues to strengthen its standing as one of the world’s most advanced advertising technology, data and service providers.

Tap into a platform built for incredible scale

Backed by global infrastructure, we help brands connect with millions of people every day. With a long-standing heritage in identity, data and measurement, our platform focuses on driving real outcomes across channels and markets.
