开发信的主题是我们开发信首要，也是吸引客人看你邮件的兴趣点，写的好，回复的多，客人当然也多咯。废话不多说，现在我把我关于开发信的主题心得案例说一说；

大众:

1.产品名+产品特色

Supplying High Quality and low price Chemical Raw Materials

2.公司自我介绍

High Quality Chemical Raw Materials Supplier

3.公司名+公司产品

BBC company /manufacturer of Home Depot

4.产品特色+原产地，

High Quality Chemical Raw Materials from China。

推荐：

1.如果你给知名的大买家供过货，那就这样写：

Chemical Raw Materials /***'s supplier/Manufacturer!!!

（突出实力经验）

2. 写出对方的名字或者公司名+产品名+自己公司名
ABC company/ Chemical Raw Materials/ BBC company

（一般有对方的公司名会更正式，阅读率应该算是最高的，但是发信速度也是最慢的，而且最后留下自己的公司名加强对方记忆）

3. 写出对方的名字或者公司名+产品名+一些抢眼的字眼

ABC company/ Chemical Raw Materials/ High Quality and low price

(抢眼的字眼不仅仅包括质量价格，太多人用了，可以对应你自己产品的卖点和你公司的优势，如证书，出口权，灵活的付款方式，交期准时，服务好等等。)

4.、如果是广交会的开发信主题

对方公司名字+询价的产品名称规格等等+公司名

ABC company/ Chemical Silicone Raw Material DMC/ BBC company

4、加上Re有一种回复的感觉

产品名+写出对方的名字或者公司名

RE：Chemicals contact/ ABC company

5. 对方公司网站标语

想给巴黎欧莱雅供材料：邮件标题是“你值得拥有

（这样对方肯定会打开，开拓一下不仅仅是标语，公司明显的，核心价值(core value)，总裁致辞等等，也会吸引对方，也让你的邮件独一无二。）
