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.
RocketMail
On 19 June 2008, Yahoo! started the RocketMail brand again by allowing new users to sign up for accounts under the rocketmail.com domain, which had not been possible since its acquisition of Four11 Corporation. In April 2013, Yahoo! closed support for creating new Rocketmail email addresses; existing Rocketmail accounts were not affected.
