Loyalty & Personalisation

From loyalty programme to growth engine: dunnhumby helps retailers turn customer data into profitable growth

The opportunity

The top retailers today know exactly what their customers need. The insight already exists in your data, the opportunity is in how you use it.

Customers expect to be understood as individuals: relevant offers, timely communication, experiences that reflect how they actually shop. When that expectation is not met, they disengage. When competitors do it better, they switch.

The retailers pulling ahead have made loyalty foundational to their operating model. Not a CRM programme measured by redemption, but a core capability powered by first-party data. Pricing, promotions, category strategy, and retail media all get sharper when built on behavioural understanding. That starts with loyalty - an approach dunnhumby has pioneered for 35 years.

Ben Snowman, Head of Loyalty & Personalisation

“Retailers that outperform are using loyalty as a strategic lever, not a promotional afterthought. They understand that loyalty doesn’t exist to drive exclusivity – rather, it exists to shape shopper preference. As such, the goal is to increase the likelihood that this retailer is chosen for this mission at this moment – and repeat.
