A sales letter should be brief and strong. Recipients do not like to read lengthy letters, and most people will lose interest if your letter is too long. Therefore, the most effective technique is to include your strongest sales pitch in your letter and include further explanations, diagrams, photographs and testimonials in your tri-fold. This insures that your most important points are read in your sales letter and interested recipients will have the ability to obtain more information with your tri-fold.
