I've cloned a campaign that I want use again but would like to delete the lists that I do not need for the new campaign. How is this done? I'm getting the following error message:
When you cloned the campaign, all the smart campaigns and other objects were reset to use the newly-cloned lists. Meaning, you need to go into the smart campaigns and everything else and remove references to the lists you want to get rid of before you'll be able to delete them.
