Yahoo! Mail
Yahoo! Mail is an email service launched in 1997 through the American parent company Yahoo!. Yahoo Mail provides four different email plans: three for personal use (Basic, Plus, and Ad Free) and another for businesses. By December 2011, Yahoo! Mail had 281 million users, making it the third largest web-based email service in the world. Since 2015 its webmail client also supports managing non-Yahoo e-mail accounts.
Yahoo! Groups
Yahoo! Clubs was launched in 1998 as a logical extension of services that had already been developed by Yahoo - message. Unlike previous Yahoo products, this product was designed to allow much deeper levels of user control over creation, membership and overall direction of communities. Development was led by Doug Hirsch (product management) and Matt Jackson (lead engineer), both of whom have since left the company. Yahoo! Clubs quickly grew to be one of the largest traffic-generating products within the Yahoo! network of services.
