Extracting Mailing Lists
In List Manager, you can remove duplicate and blank e-mail addresses from a generic list, leaving only the necessary fields for a mailing. The resulting list is a more accurate count of the number of unique e-mail addresses contained in the list, making the list more useful and increasing performance during runtime.
