Mazda used social and email to help promote its first all-digital pre-sale event for limited-edition MX-5 Miata cars. The car maker announced the sale back in April at a trade show and through active social messaging online. The messaging led to a microsite where Mazda collected email addresses. They collected 1,600 email addresses through the effort. In May, Mazda emailed the list to announce the pre-sale and generated 250 sales leads in the first 10 minutes of the promotion.
