Cleanse Address Databases

Maintaining a clean, duplicate-free customer, supporter, member or prospect address database is foundational to effective marketing, high quality service and on-time delivery.

Cleansed addresses make access to Royal Mail postage discounts possible and data analysis more reliable. This protects reputation and supports sound financial management.

Duplicate customer records cause confusion by preventing a 'single customer view'. They cause waste and embarrassment when the same mailing is sent to the same customer multiple times. They cause financial issues when credit is inadvertently extended multiple times to the same individual or organisations.

AFD solutions enable easy deduplication by identifying potential duplicate customer or prospect records.

Geocoding and Appending

Our cleansing solutions come with valuable data that can be appended in the same pass as cleansing. For example:

  • Grid references enable visualisation and “where’s my nearest” functions.
  • Affluence and life-stage indicators (geodemographic codes) enable profiling, analysis, insight and better directed marketing resources.
  • Just Built data identifies newly built properties who tend to spend more on services and products.
