You can easily create new runs of an existing smart campaign directly from the program schedule view.
Go to Marketing Activities.
Select a program that contains your smart campaign.
In the schedule view, click the day you want to set your new run for, and give your entry a name that’s easily understood (e.g., “Second Invite”).
Select the entry type menu drop-down, and pick the smart campaign you’d like to rerun.
You can also do this from the program focus.
Boom! Just like that, you’ve scheduled another run for that smart campaign. If that smart campaign contained send email steps, you’ll see those too!
