Client Problem
For passengers, time matters. They need to know about cancellations, diversions and closures before they begin their journeys.
A major UK public transport organisation needed a reliable way to communicate planned service changes, while managing millions of customer records accurately and securely.
What began as a simple mailing file grew into a long-term programme covering customer data management, communications and operational support.
The organisation also needed flexibility to support customer enquiries, application processing, campaign analysis and fulfilment as requirements changed.
“Bearing in mind the sheer amount of campaigns that we run, we couldn’t have achieved the level of positive customer interaction without Dawleys support. They certainly make life easier and consistently deliver accurate data and timely campaign support.”
How Dawleys Helped
Dawleys supported the organisation for more than 14 years, providing the people, processes and technology needed to manage large-scale customer data and communications.
We built and managed a central database of more than 7 million records, combining data from multiple transport services and customer touchpoints. This provided a reliable foundation for accurate, secure and relevant customer communications.

Data Transformation
Managing millions of customer records each month required a robust approach to data quality. Data from multiple sources was securely standardised, matched, combined and de-duplicated to create an accurate customer database.
More than 20 matching routines, from exact to high-confidence fuzzy matching, helped ensure records were processed consistently while maintaining data quality and integrity.
Data Handling
Data security was central to the service. Customer information was retained only for the agreed operational period before being de-personalised for analysis.
This enabled the organisation to use customer insights to evaluate campaigns and improve future communications, while maintaining a controlled and secure data-management process at scale.
Passenger Communication
Dawleys delivered targeted service communications to help passengers make informed decisions about their journeys.
The team managed communications covering planned works, closures and service updates, helping passengers avoid disrupted journeys and stay informed.

Operational Support
The partnership grew beyond data and email communications. Dawleys also supported customer registration, application processing, passenger enquiries, fulfilment and campaign analysis.
By bringing these activities together, Dawleys provided practical operational support across customer data, communications, enquiries and fulfilment.
