Is this a one time occurrence, or will you be running this same campaign multiple times?
People would not receive duplicates in the scenario above if you a running (or scheduling) this campaign only once. Since this is a batch campaign, each lead would run through the first email flow step only once and would run through the second email step only once (assuming they did not click).
If you click on the "Schedule" tab on you smart campaign and click on the number of leads set to be affected, this will give you the list of leads that will receive the first email. There shouldn't be any duplicate on this list. Thanks!
This campaign will only run once. Thanks for the clarification! That's what I thought, but I wanted to just make sure I understood correctly.
