If the channel you have connected up to Shiptheory supports sending the delivery date across to us, you can use one of the below services to send that date across to Pall-Ex, any other service won't send the day across as only these are day specific services

Premium Saturday AM
Economy Specific Day

If you're not sure whether or not your channel is able to send across the delivery date, please check here for a list of our supported channels.

If you have any other queries please feel free to get in touch with our support team who would be happy to help
