I have a custom object that has a Due Date field that I want to fire off emails 21/14/7 days in advance notifying the owner that the record is almost overdue. I have used Process Builder that sends emails at these particular timed intervals but it also fires off an email when the record is updated.
How do I send an email 21/14/7 days prior to the Due Date that only reevaluates the Scheduled Action when the Due Date is edited and not when the record is edited. (The Due Date is likely to be changed occasionally)
