产品有缺陷是正常的，一个产品从最初研发，到被消费者和市场认可，需要一个过程，中间会经历很多次的修改。这就需要跟客户保持互动，根据己方的理解来优化产品，给客户改进方案以供选择。
一、邮件模板
Dear Marie ,
l suggest we change the outer carton to 3-layer corrugated carton. The ones in last order were just 2-layer items，and were easily broken when delivery.
You do the mail order business ,and the packaging for each item is really important. Each carton should pass the drop test，to make sure the boxes are solid enough to protect the goods inside.
The unit price has to be added USD 0.40/ pc. Let's go 50 and 50，OK?
Best regards ,
Maggie
