Case Study: Global Telecommunications Operator achieves personalized one-to-one offers and strong conversion gains with Eulerian Technologies' DMP

How a telecom operator proposes tailor-made offers to its customers thanks to the DMP

Global Telecommunications Operator, a large French telecom leader with tens of thousands of mobile customers and millions of ADSL households, needed to put data at the center of its digital strategy to reduce churn, personalize offers and improve ad campaign ROI. The operator selected Eulerian Technologies and its Data Management Platform (DMP) to centralize CRM and multi‑device browsing data and enable people‑based, one‑to‑one marketing.

Eulerian Technologies’ DMP consolidated CRM and behavioral data, created targeted segments (anti‑churn, cross‑sell, eligibility), and activated campaigns via adserver, programmatic DSP, Facebook and personalized search. The program reached 25% of a 10M customer base, matched 1.4 million emails/phone numbers, halved CPA on Facebook, delivered a 4× conversion uplift with adserver scenarios versus generic banners and a 2× conversion uplift on the anti‑churn segment with programmatic activation — demonstrating clear, measurable impact from Eulerian Technologies’ solution.
