简单的 Payment received, all item(s) on the order list will be shipped on XX/YY/XXYY.
正规点的一般也就开头来个 Dear Customer:
然后
Payment for your order#: XXXYYYY has been received, thank you very much for your business.
然后也看你们是否有搭配的订单列表, 可以说 All item(s) for order #XXXYY will be shipping on XX/XX/XXYY
然后下面附带订单表格...
通常情况下后面还应该有 Tracking number: 的..如果发这邮件的时候已经有了tracking#, 那么可以直接在SHIPPING日期后面逗号, 然后添加 tracking #: xxxxxxx 句号后, 也可以看情况加一个Hope you'll enjoy our products. 或者添加售后服务之类.
最后再来个
Sincerely
