Net Tech Term: email appending

[Keefe]

The process of merging a database of customer information that lacks e-mail addresses for the customers with a third party's database of e-mail addresses in an attempt to match the e-mail addresses with the information in the initial database. A typical e-mail appending scenario involves a business that has name, address and telephone data on its customers to do business through mail or over the telephone, but the company wants to expand into e-mail communication and pays a third party that has a database of e-mail addresses in order to merge the data together.
