ShipStation sends two types of notifications:
Marketplace notifications are the notifications sent to your selling channel to let the selling channel know the order has been shipped.
Customer notifications are the emails sent to your customers to let them know their order has shipped.
ShipStation sends these notifications according to the notification options in your Store Settings. Should you ever need to resend either of these notifications, or if they fail when initially sent, use one of the methods listed below to resend them. This will ensure both your selling channel and customer are notified correctly.
You can resend notifications from the Shipments grid, the Order Details screen, or Shipment Details screen.
