Email newsletters can be A tired tactic, but Mercedes-AMG has found a way to drive excitement for owners of high-end models. The "Private Lounge" emails create an aura of exclusivity. There's a dual message: "we haven't forgotten you after the showroom - and innovation continues, so we've got a better road rocket for you when you're ready." The linear design of the newsletter is easy-to-follow. More important, the photography jumps off the screen à la a sleek magazine. Links to exclusive video are a winner. So are dream opportunities, such as a chance to attend a private driving academy on a speed track.
