Actually, it depends on the mail server. Some will filter duplicate addresses, but not all.


When using multiple distribution lists to create a single combined
list, if a person is included in more than one list, will they
receive multiple e-mails?

They should not receive multiple messages.

Since there are differences between servers and a chance there may be
duplicates, I did a quick test. We did not get multiples. Thanks for your
quick replies.
