Please note that future correspondence for shipment GH234 should be to Ms. GiGi. Her details are included 'in the cc copy' (you could perhaps include more information here e.g. subject of the letter, date, etc. Sandy will follow with the 'other account's shipment' (I don't understand this - who is the 'other account'..is it new account details for the same shipment GH234?)
Hope this is of some help.
