The reason you write sales or pitch letters is simple: You have a message you want to deliver to the letter reader. In today’s electronic world, you may deliver the written word in a format other than ink on paper. Your letter might be delivered via e-mail, or as an open letter on a Website. Some letters are still delivered via fax (facsimile), but those seem to be dwindling in many different industries.
The more you know and understand the reader of your sales and pitch letters, the easier it will be to get your message across. Some letters will be for the masses, where the audience is not clearly defined. Other letters will be for specific audiences, such as your customers who have already bought a specific product or service from you.
