Personalization at scale
Tailor marketing messages, content and creative to individuals at scale with ease.
Epsilon’s industry-leading COREai provides the decisioning mechanism needed to deliver personalization at scale.

Saying the right thing to one person is simple; saying the right thing to everyone is incredibly complex.
Engaging in relevant conversations at scale requires millions of real-time decisions. Epsilon’s COREai analyzes massive amounts of continuously evolving data to determine not only what to say and to whom, but also where, when, how often, and how much to spend, while synchronizing messages across your paid, owned, and earned channels.
Marketers are often drowning in data but lack insight into who their customers are and what matters most to them.
Their attempts to deliver a relevant message to each individual further suffers from an inability to make decisions in real time when they engage consumers across paid, owned, and earned channels.
Epsilon's COREai harnesses the power of predictive and generative AI to synthesize thousands of data points into a robust understanding of any individual. Who they are, what they care about, how to engage them – where, when, how often – and how much to spend to engage them, based on likely performance and long-term potential.
COREai then puts that knowledge to work, helping you decide when to engage each person (or when not to engage them), how often and on what channels, and what to say to them—ensuring each individual conversation is harmonized across your paid, owned, and earned channels.
Accurate measurement requires analyzing a myriad of data points to understand whether your marketing actually moves the needle. COREai not only improves the accuracy of your campaign measurement but also creates an accurate representation of customer lifetime value, the customer journey with your brand, and the path to purchase.
To ensure your AI is effective at scale, it needs to work in tandem with identity resolution and intelligent creative. With all three, your use cases greatly expand.
