Mike Martin, Director of Admar Ltd, gave a presentation at the BizGen Conference and Expo Lincoln about how data can help or harm companies. He discussed questions to ask when purchasing lists such as how the data was collected and screened, how often it is updated, and restrictions on use. Martin also covered topics like data decay over time, compliance with the Data Protection Act, and finding firm foundations for marketing plans through data profiling.
