Hi there,
We use Royal mail as one of our shipping carriers, who offer an SMS and email notification as part of their service. Within Shipstation there is an option to select whether you wish to opt in for this service, which has to be done per shipment. We send approx 650 parcels per day via Royal mail, therefore takes a fair amount of time to do this manually per order.
I think it would be a great option to allow these to be selected by default, or to be able to automate the opt in of these notifications.
Many thanks,
Dan
