Case Study: a major bank restores compliant marketing and unlocks revenue with Dufrain

Major Bank unlocks 4.5m customers with Dufrain

The customer, a major bank, faced a significant challenge when it had to halt most of its customer marketing due to non-compliant and fragmented data. Multiple systems held conflicting versions of customer preferences, severely limiting engagement and revenue generation. The bank engaged Dufrain to implement a data-driven solution that would remediate these preferences and restore marketing capabilities in full compliance with PECR and GDPR regulations.

Dufrain developed a single view of customer marketing preferences to strategically identify and segment affected groups for remediation. This solution, supported by a comprehensive Tableau reporting suite, standardized millions of records. The outcome provided the bank with a clear, compliant view of its customers, unlocking 4.5 million people for marketing. As a result, Dufrain enabled the bank to forecast tens of millions of pounds in additional annual revenue.
