Promotional data are data about customers, such as addresses, names and phone numbers. In Connect, each record in the extracted record set represents one recipient. The number of fields that contain promotional data is the same in each record. These data are stored on the root level of the extracted record. See Extracting data.

Transactional data are used in communications about transactions between a company and their customers or suppliers: invoices, statements, and purchase orders, for example. Naturally these data differ per customer. They are stored in detail tables. The number of fields in a detail table can vary from record to record. See Extracting transactional data.
