如果没有等到客户回复，重新编辑，改变一下邮件内容，再次发送，当做提醒一下客户。邮件加上高优先级。重点提及几个行业内在做的知名客户和质量认证，吸引客户回复。

如电话中：
Hi David~

第一种情况，客户不是很专业，那么答应客户很高兴寄送样品。（你就准备那个价格低的样品）。另外再和客户推荐，你的市场上我们另外一种产品卖的也很好，质量要好一些（同样不说克重），很多客户也买这种。我一起寄给你看看，你觉得怎么样？客户大多数情况下是很乐意的。
小学五年级英语试题客户要到快递账号然后把两种样品寄过去，客户肯定会喜欢后一种质量好点的。会问你价格，然后你开始介绍，报价（同样不必写克重，以我样品为准）。这时你看，我们已从被动的局面转为主动。 什么是服务>何炅资料
