Data Health Check Case Study

Bureau Data Health Check for Customer Records

The Challenge

A client approached Hopewiser seeking a comprehensive ‘health screening’ of their customer database. Their input file contained:

Customer Numbers
Names
Addresses

They needed to verify address accuracy, identify deceased or gone away records, and eliminate duplicates, all to ensure their communications were compliant, targeted, and cost-effective.

The Solution

Hopewiser implemented a two-pronged strategy using AtlasBatch and AtlasDedupe to deliver a comprehensive data health check.

First, AtlasBatch was used to validate customer addresses by matching them against official datasets, ensuring accuracy and consistency. The same process also screened for suppression indicators, flagging records associated with deceased or goneaway individuals, and where possible, provided updated forwarding addresses to support re-engagement.

AtlasDedupe was then applied to identify and flag duplicate entries within the dataset, helping the client streamline their records and eliminate redundancy.

The final output file included fully matched and corrected addresses, warnings for any non-matched entries, suppression flags for sensitive records, and duplicate markers to support efficient data cleansing and decision-making.

The Outcome

The client received a clean, structured dataset ready for confident use across marketing, compliance, and customer service. This process has since become a routine engagement, helping them maintain data integrity and reduce waste.
