An Email Marketing Glossary Entry

What is Deduplication?

The process of removing identical entries from two or more data sets such as mailing lists. AKA merge/purge. Delivered email: Number of emails sent minus the number of bounces and filtered messages. A highly inexact number because not all receiving ISPs report accurately on which email didn't go through and why not.
