你直接每天重复问有么有反馈,肯定是没用的。你得学我这样问:I wonder if you have chance to review my product catalog.Is there any comment?Please kindly come back to me and let's see what we can do to support you.(Your response is a great help for me to meet your request and offer you better service,please give me a hand.)你这样发,客户一定会回复你
