Struggling to figure out how to send out an email when a delivery date is changed/updated. I tried a RT workflow that triggers before the field changes to check if there is an existing value and then fires a child workflow which again checks whether or not the field has a date and then emails the new value to a dispatcher. It works for the most part except it fires when the field starts off null, which I can’t figure out why. Maybe there’s another way to achieve this?
