For our business, it would be very profitable if we had delayed shipment notifications that worked. In the past, we did it because in case if we had to cancel one of our customer orders for whatever reason (no inventory, back order, etc...) we suspend the shipement without the customer getting notified that their order was shipped. As of right now, they get notified once the shipping label is created. When we had the delayed shipment option set to "once the mail hits the mail stream" it was very hit and miss. The problem with Amazon is every time we have an order that is shipped late, our metrics go down. We predominately ship using the Post Office, and once our Post man comes and picks up our orders, he scans in the orders into the system. For some reason, it doesn't work all of the time. Is there something that I am missing, or is this a bug on Shipstation's side? I would like to think that there is something I am missing. Any help would be good. Thanks.
