If you have a recurring batch campaign that you don’t want any more, you can cancel the future runs.
Select the campaign and go to the Schedule tab.
Click Edit Recurrence.
Set Recurring to None and click Confirm.
This cancels future runs, but if a smart campaign is in process of running, you cannot cancel it.
Select the campaign and go to the Schedule tab.
Click Scheduled Runs.
Find the single run you want to cancel and click the X on the far right.
Clicking the pencil icon allows you to edit that single run.
