Re. #3: Proof by demonstration is extremely important. I refer you to my “Wealth Magnet #11” (pp. 94–107) in my book No B.S.Wealth Attraction in the … - Dan S. Kennedy

Acquiring a deep understanding of the target customer should not be short-changed — by anyone writing sales copy, at any time, for any purpose. As I was writing this edition of this book, I was writing copy for a long-time client, the Guthy-Renker Corporation, for their hugely successful Proactiv® brand of acne products. There are three different people to talk to about this — the teen sufferer, the teen's mom, and playing the odds, the adult female sufferer. This had me reading past and current issues of nearly a hundred magazines, including all the teen and preteen magazines, all the mom magazines, and all the women's magazines, having copious online research done for me, doing “conversational research” directly with people in all three groups, and even hiring a dozen freelance readers — teens, parents of teens, and young women — to critique my copy. Also, as I was writing this edition of this book, I began work on copy aimed at highly successful, professional financial and investment advisors, financial planners, and top-performing life insurance and annuities agents, which required a similar investment of time and energy in crawling inside their psyche, tribal language, daily experiences. Freelance writers worth their salt know they must do this sort of thing, and do. The danger for the business owner writing copy for himself and for his own business is ingrained assumption — encouraging shortcutting or altogether neglecting this step. The only sure way to keep your own accumulated but untested opinions and beliefs about your customers from sabotaging your sales letters is to start anew, from scratch, and to engage in getting to know the customers just as if you were arriving to write for them for the first time, with no foreknowledge.

Another client, a trade school, requires prospective students to furnish letters of reference.

Unfulfilled envelope promises destroy the credibility of everything enclosed and everything you have to say.
