Epsilon Digital – Tie every ad to a real person and a real sale

Tie every ad to real people and real sales.

Your digital ads are seen, but by who, how often, and did they buy? Epsilon Digital connects every impression to a real identity and ties it to actual purchase outcomes.

Cross-channel activation and measurement in one platform. Remove the guesswork between exposure and sale.

Find out what your media plan is missing.

In our 30 minute consultation, we’ll explore how identity-led advertising could improve your business outcomes and where you’ll benefit from immediate impact. No pitch deck. No obligation.

True identity. Unique reach.

COREid resolves fragmented data into a single, deterministic identity: a real person recognised across display, video, CTV and audio, not a cookie or a device. That means you de-duplicate audiences, separate new prospects from existing customers, and stop paying for reach you've already got.

Sequenced messages, controlled frequency, via one platform.

Epsilon Digital runs cross-channel campaigns from one platform with person-level frequency management. Messages are sequenced, not repeated.

Reach is de-duplicated, not double-counted. In a head-to-head test: 30% more unique customers reached, 176% higher revenue and 136% higher ROAS versus a leading DSP.

Clicks don’t prove anything, sales do.

Epsilon links ad exposure to downstream purchase behaviour, so you replace vanity metrics with revenue-based outcomes.

Epsilon is the only digital media platform accredited for Correlated Outcomes, meaning the connection between your ads and sales is independently verified, not modelled.

ROAS

FatFace needed to prove that digital media was driving real sales, not just online clicks. By integrating CTV, video and display through Epsilon’s identity-led platform, they engaged 950,000 new prospects through CTV alone and generated 3x incremental revenue from the integrated approach.

The numbers didn’t just validate the investment, they changed how FatFace plans every campaign. Continue Reading...

When display, OLV, and CTV were combined through Epsilon, conversions rose 46% compared with display alone. And with nearly 7 store visits per 1,000 impressions, the campaign proved the power of coherent, multi-channel engagement. Continue Reading...

Clicks don’t make sense in a CTV context, but most brands still can’t prove CTV is reaching new people or driving anything beyond completion rates. This guide covers what to look for in a CTV partner, how to measure incremental reach, and why person-level identity changes the economics of broadcast-quality advertising.

Frequently Asked Questions

How is this different from what my DSP already does?

Most DSPs use probabilistic data or cookies to estimate who they’re reaching. When those identifiers drop off or rotate, your frequency caps break, your audience insights degrade and your measurement relies on models rather than observed behaviour. COREid uses deterministic, name-and-address-level identity validated against real transaction data, so the person you target on display is the same person you measure on CTV.

What does ‘accredited for Correlated Outcomes’ actually mean for me?

It means the connection between your ad exposure and a purchase has been independently audited and verified. You’re not relying on Epsilon’s word, you’re relying on a methodology that’s been stress-tested by the industry’s measurement body. Epsilon is the only digital media platform with this accreditation.

We already run CTV, display and video. Why would we consolidate onto one platform?

Because running channels separately means you can’t control frequency across them, can’t de-duplicate reach and can’t sequence messages. The same person gets the same ad seven times on one channel and never sees your follow-up message on another. Consolidating onto one platform with person-level identity gives you true cross-channel frequency control, sequenced messaging and unified measurement. 61% of marketers say performance and efficiency are their main drivers of digital investment. You can’t get either if your channels operate in silos.
