San Francisco—Email company ExactTarget has launched Social Forward, a social-sharing solution that allows marketers to track the sharing of their email campaigns across numerous networking sites.

The company is incorporating icons of such networks as Facebook, Twitter and MySpace in its email product. Also, via a partnership with social media syndication company ShareThis, users can connect easily to more than 40 social media sites with a single click of a ShareThis icon.

Social Forward will be available to users through ExactTarget’s online Innovations Lab starting May 1 and will become an integrated solution for all ExactTarget users as part of the company’s summer product release.
