Epsilon

Epsilon operates as a unified messaging hub where email, SMS, direct mail, and loyalty programs connect through a central first-party data store. The platform lets brands build a single view of each customer and deliver coordinated messages across every channel they use, from traditional postal mail to modern mobile messaging.

This platform appeals to large enterprises with established customer databases and cross-channel ambitions who need mail still integrated alongside digital channels. Epsilon's strength lies in its ability to orchestrate campaigns across traditional and digital media in one system, making it particularly valuable for retailers and financial services firms with multi-channel customer relationships.
