Personalize messages that drive conversion
Deliver campaigns with the right message and creative in the moments that matter to drive maximum performance.
Epsilon’s industry-leading COREid provides the recognition needed to deliver personalization at scale.

If you don’t recognize the person you’re speaking to, it’s hard to engage in a relevant conversation.
Doing this at scale requires recognizing every individual in the moment, wherever they are—in your systems and across channels. Epsilon’s COREid connects fragmented data to real people, and real people to your messaging across paid, owned, and earned channels.
Marketers' customer and prospect data is dispersed across teams and systems, leading to a fragmented and incomplete view of any individual.
And delivering relevant messages across paid, owned and earned channels is further complicated if they can't recognize a person when they encounter them.
Epsilon COREid unifies what you know about individual consumers from interactions in various channels across disparate systems. And when augmented with Epsilon's proprietary demographics, psychographics, and buyergraphics—as well as data from other partners—you can create a single, robust and unified View of any individual.
COREid also plays a crucial role in engaging consumers through marketing and advertising campaigns. Armed with the ability to recognize consumers wherever they encounter them, you can engage each individual with a voice that is harmonized across their paid, owned, and earned channels.
Accurate measurement requires mapping exposure and outcome data back to an actual person, not just a digital identifier. COREid is the industry's only 100% deterministic, person-level identifier mapped to a verified name and address. This allows you to truly understand the impact of your marketing and advertising.
Once you recognize an individual, you need to be able to decide in real time what to say to them and be able to say it. That’s where AI and intelligent creative come into play, which greatly expands your use cases.
