GlobalPost is available in my Shipstation Account. When the package weighs more than 4 lbs the following message is received: Selected service is not compatible with other settings (package type, weight, size)
GlobalPost indicates that packages ca be sent up to 70 lbs. How can a package over 4 lbs be sent using Global Post through Shipstation?
The max weight for GlobalPost Economy services offered within ShipStation is 4.4lbs. You can review the weight limits and services available here: GlobalPost Services.
GlobalPost Standard packages do allow a max weight of 70lbs - so you would either need to select the Standard service with a package type of "Package" or choose another, non-GP service for your shipment.
