Data appending is the practice of adding additional data from a different source to an existing data file. It is often used in digital marketing to add relevant customer information, such as email addresses, phone numbers, or demographics to an existing customer file. By adding additional data, companies can not only create more accurate and comprehensive email lists, but they can also use the wealth of additional data to create stronger analyses. For example, healthcare organizations can use lifestyle data of their patients to create targeted consumer outreach programs that are more effective.
