Actually unless I've missed it, ZC does not have the functionality to send an order shipped e-mail to the customer without a change of status. The only way to do it would be to change it from the shipped or the delivered status which is set when stamps adds tracking info to the comments. It would seem to be a better solution to have stamps trigger the e-mail at the time they add the tracking number.
