Manage email addresses

Last Modified: 2014-01-14
We have multiple email lists for our newsletter. I have the ability to combine lists and remove duplicates but I need to be able to output a list of email addresses that appear in one list but not the other. So list A has 150 addresses and list B has 100. Both have similar and different email address. We want to create list C which contains only the email addresses that do not occur in one or the other list.

If there's an out of the box solution, that would be great but I think we could program an Excel file to do the same.
