Identify your unknown customers

Capture customer signals—no matter where they interact with your brand.

Struggling to identify unknown customers? If you don’t have key transactional data points like names, emails and other identifiers, you won’t be able to connect with the people who are already buying with you in a meaningful way. To understand them, you need integrated tools that enable you to reach them with personalized messages across paid and owned channels.

How it works

Identify real customers

By leveraging first- and third-party data, Epsilon’s integrated solution gives you a single view of every customer and all their associated touchpoints, so you can have a deeper understanding of the customers you already have. Data hygiene solutions can identify missing contact fields like names and emails and help you fill in the gaps.

Map out better, smarter campaigns

With new insights on previously unknown customers, you can know who to engage, when and with what kind of message. It could also mean suppressing people who made a purchase recently in a particular category (or even a specific item). After all, being able to exclude people from your marketing efforts is just as powerful as being able to add them.
