Sales letters are used to introduce products or services to consumers. As such, sales letters tend to use formal letter structures and are rather impersonal because they are sent to more than one person. Sales letters often ask readers to consider a "pain point" - a problem that a person needs solved, and then introduce a product that will provide the solution. It's important to quickly move to your sales pitch in your sales letter as most readers will understand that your sales letter is a form of advertising. Sales letters also often include an offer to encourage customers to try the product. It's important that these offers are clear and provide a useful service to the reader.
推销信是用来向顾客介绍产品或服务的。因此,推销信通常采用正式的书信结构,并且无人称,因为信件的接受者不止一个。推销信常提醒读者考虑一件麻烦事——一个必须解决的问题,然后再介绍能够解决这个问题的产品。之后,马上在推销信中推销产品,因为大多数读者都知道推销信也只是广告。推销信往往包含鼓励顾客试用产品的优惠。提供的优惠措施必须清楚明白而且能为读者带来有用的服务。
