Girls Learn to Ride, a website for young women who like to snowboard and do other extreme sports, is reaching out to social networks to increase its email list, writes DM News (via MediaBuyerPlanner).

The site has 10,000 names in its email database, but it has a combined 50,000 friends in social networks such as Facebook, MySpace and Sponsorhouse. It sends out daily bulletins to its social networking "friends," encouraging them to sign up for the email list.

The company's largest growth has come from the social networks. Interestingly, emails to the social networks result in the highest conversion rates, as well.

The firm is expanding into the over-21 market with Women Learn to Ride.
