To be effective, the scope of a sales letter must identify one or more of the following:
A problem that can be solved
A need that can be fulfilled
A desire that can be satisfied
A pleasure that can be gained
It must then present an attractive solution in a manner persuasive enough to accomplish the objective of the letter, convincing the reader to make a purchase.
Successful sales letters gear their pitch toward the benefit received by the reader rather than the actual goods or services being offered.
In the sample sales letter, the writer highlights the drudgery of a common chore and states how the service being offered will remove the burden and provide an ongoing solution.
