Hi;
I have received payment for your _(item)__ and it will ship today via.........(name of logistics service) with Delivery Confirmation.
On receipt it will be important for you to email me to let me know it has arrived safely and that everything is in order so I can leave feedback for you and you can then leave feedback for me. As a way of making sure my customers are satisfied, I prefer to leave feedback on notification of safe arrival of the product.
I know there are many choices today in buying just about anything and appreciate your business and prompt attention to payment on this transaction.
Sincerely,
(Yourname/ID)
