This element can be used to recognize the parcel partner type where a parcel is announced. When a parcel is announced at Post NL for example, there is a track and trace website where a customer can post the track and trace barcode, together with the zip code to track a parcel.
Use this element to determine the used parcel service, so correct hyperlinks can be used within the email message to the final customer.
Please keep in mind that we can't help with url's of parcel services. You can use trial and error, or just simply contact them.
