How do you test? The classic method is A-B testing. We want to test offers. We divide the list into two 500-name segments by selecting every other name for one list, and alternating names for the other. We mail Offer A to one segment and Offer B to the other. We compare results to determine which offer works better. Offer A gets 4 orders. Offer B gets none. We now know something more about the list. Using this type of split testing, you can test almost any attribute of a promotion. Want to test a price? Offer A and Offer B. Want to test a layout? Layout A....

Fen-Phen: A Lawyer's Perspective... Fen-phen, a diet drug consisting of fenfluramine and phentermine, had been considered safe for many years until the FDA requested its removal from store shelves in 1997.

Fen-phen has also been pinpointed as the drug responsible for causing dozens of cases of a rare valvular disease in women, as reported by the Mayo Clinic in July, 1997. Identification of this condition caused doctors to begin to warn their patients of the dangerous risks and conditions that could occur as a result of using Fen-phen.
