A Silicon Valley company will soon give television networks and movie studios a compelling new marketing tool: the opportunity to insert video directly into emails. The platform from Goodmail Systems will allow email recipients to view a "Grey's Anatomy" promo or movie trailer just as they open a message. Networks such as NBC and TBS are among those that send out electronic newsletters and could capitalize on the new Goodmail system. Programmers might also be able to sell advertising such as pre-rolls before videos or stand-alone spots. Currently, due to safety issues involving Internet Service Providers (ISPs), marketers can't embed video in the promotional newsletters and other emails they send out. The best they can do is offer a link for users to click through to watch video on another page. Goodmail will begin distributing the system, known as Certified Video, early next year in partnership with AOL, Yahoo, Cox, Comcast and others. While it may be tailor-made for media companies, the platform can help marketers in all fields place ads or informational clips in emails.
