I did not realize until numerous complaints that customer were not receiving tracking information. The problem is that after importing the orders, the email address in only in the BILL TO address, not the SHIPTO.
If you could have the email address on both side, then SHIPPO could send the customer tracking info.
See https://goshippo.com/docs/tracking/
Please consider this urgent.
Thanks.
