Magazines have long been among the most sophisticated users of direct mail (for the very latest look at trends, into both direct mail and email marketing by magazines, along with extensive analysis, see DirectMarketingIQ's just released Magazine Publishing Industry Sector Report). Many fine copywriters and designers cut their teeth on subscription packages and developed giant reputations as a result of their ability to sell subscriptions through this channel.
I've been able to work with a lot of wonderful direct marketers over the years, including the late Jack Shurman and Joan Throckmorton. Both of them taught me a tremendous amount about direct mail and subscriptions marketing. That's how we learn, by working with practitioners who understand direct marketing and are willing to teach others what they know. Joan and Jack passed along to me a love for magazines and a love of a very old advertising discipline: direct mail.
