Case Study: Epsilon achieves 1,000+ hours saved per month building, testing, and delivering emails at scale with Litmus

How Litmus helps Epsilon save more than 1,000 hours per month building, testing, and delivering exceptional emails at scale

Epsilon, a leader in outcome-based marketing, needed to produce high-quality, personalized emails at scale for enterprise clients while ensuring flawless rendering across dozens of apps and devices. With hundreds of dynamic content variations and a 200+ person global team, they faced long QA cycles, collaboration bottlenecks, and the risk of rendering errors that could hurt campaign ROI.

By integrating Litmus (Builder, Email Previews, dynamic proofing, and subaccounts) into Epsilon PeopleCloud Messaging, the team standardized QA, caught rendering issues early, and reduced the need to maintain multiple physical devices. The result: faster, more reliable email production—saving more than 1,000 hours per month (about 15–20 minutes per message) and streamlining workflows across the organization.
