DupeX is an easy-to-use application that will let
you quickly find (and remove) duplicate email addresses from a mailing
list. If you manage a large mailing list, it can help remove duplicates
and keep your list pristine.
A simple step-by-step interface lets you select a text file containing
the addresses. DupeX will scan the file and report on duplicates found,
letting you save (in plain-text or comma-separated format) both the
unique addresses and the duplicates. It will also compare up to 10
address files, combining them into one "clean" file (again
in text or CSV format) and giving you the option of saving the duplicates
to another file.
