Once you’ve got the reader hooked with your subject line and introduction you’ve surmounted the toughest challenges of writing a business letter, but that doesn’t mean that your work is done. The body of your letter is where you reveal the details and finer points of your message.The reality is that many readers will skim the body of your letter. The introduction piqued their interest and now their eager to get to the payoff — the call to action that will appear in your conclusion. But not all readers will skim past this section and those that don’t will read it very carefully, so spend some time here.
The best way to think of the body of your letter is as your showroom floor. The subject line and introduction got them in the door and interested. Now you can explain all the important things that they won’t know without your guidance. For instance, how your product compares with the competition, your firm’s record of accomplishment, other successful client engagements, or an important feature set of your product. All this education preps your reader for the conclusion, where you’ll close the deal.
Concision is important, so be ruthless about making your point in as few words as possible (two page business letters are bad). One thing to keep in mind is that this section of your letter will have a longer shelf life than any other section: by changing the intro and the conclusion, you can reuse the body material again and again and again.
