开发信如何写啊？

开发信不宜太长，也不宜过短。某些老外的超短的开发信我觉得并不十分合适。 现在很多帖子都着重申明开发信应该简短，能一句话说明白的就不要啰嗦用两句话。不过太过简洁的开发信未必效果就好。
先来说一下写好一封开发信的必要前提：

第一，标题比正文更重要。
业务员在写开发信前，必须先了解目标客户的大致背景，包括其属于什么市场，主营什么产品，对产品是怎么分类命名的，对何种产品感兴趣。再针对其兴趣点找机会对症下药。
第二，切中客户的实际和需求。
那么，如何让自己的开发信标题夺人眼球？简结、通俗，必要时有名有姓；以产品或者个人亮点为题；为避免人云亦云，通过新颖的措辞或创意吸引客户注意力，激发其好奇心；具有一定或者相当足够的煽动性。
以客户最关心的产品为标题，能促动他们的利益；在标题写上竞争者，优秀供应商，价格屠夫等作为创新的亮点，说白了就是要展示供应商的自信。其实这样拟标题，不仅是供应商的经营策略，也是站在客户的立场想问题，能直中目标客户的实际情况和需求。
