Setting/automailsendwindow

The Auto action can first trigger based on the Trigger Time and Trigger Event settings. (trigger allowed start time)

Based on other settings the Auto action may or may not be able to trigger at this time.

If it has not triggered or it is set to allow repeats, the Auto action is routinely rechecked for up to the Time Window period after the trigger allowed start time.

After the Time Window period expires the Auto action is no longer allowed to trigger.
