需要问明客人拒绝的原因吗

今早，到一份客人的邮件。原文如下： i reviewed your pricing and product but unfortunately, our client has decided not to proceed with your product.??however, i think there may be other opportunities with other customers so lets keep in touch for future sales. 广交会期间，这个客人主动和我们，问了好几款产品的价格，来往了几封邮件。现在客人婉拒了我们的产品。如果我追问对方对我们产品不满意的地方，价格或者设计，这应该不算冒昧吧？
