一般来说，业务员给客户写邮件，总以开发业务、建立市场、建立合作、拓宽产品销路为目的。外国人尤其是欧美的商人通常比较喜欢直接一些的表达，所以在写客户开发信时，不妨开宗明义，直接表达去函的目的。可以用如下表述来说明去函目的:
(1) In order to expand our products into South America, we are writing to you to seek cooperate possibilities.
(2)We are writing to you to establish long-term trade relations with you.
(3) We wish to express our desire to enter into business relationship with you.
(4)We are writing to seek more opportunities to cooperate with you for the
expanding of American market for our new model robot toys.
(5) We are writing with the hope to join hand with your company for the sales of Chinese high quality electronic products.
