Challenge
Before 2023, Kathimerini’s email strategy was limited to a small number of general newsletters sent to its full list of subscribers. The lack of personalization and segmentation meant readers received broad updates, often misaligned with their individual interests. As a result, Kathimerini couldn’t further engage with its broad audience base to enhance brand loyalty.
