Copywriter, David Yale, has a terrific site called Control Beaters, where you’ll find 24 control packages for everything from costume jewelry to collectibles to investment newsletters…and clients ranging from Publishers Clearing House to Suarez Industries to AT&T.
While these packages are from the 1990’s, what makes the site so valuable is that David shares the results of the mailings and identifies what element/s made them successful. Like this most interesting envelope for a costume jewelry offering which at first glance appears to have been mailed from Russia. It fetched a 9.38% response rate.
I especially like his comments on the lift note, “How to Avoid IPO Monsters,” which he claims doubled response in an A/B split test.
