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! Japan
Yahoo! Japan Mail maintains the classic look of Yahoo! Mail, but remains a separate service operated in Japan. Another notable change is the 10 GB storage limit, in contrast to Yahoo! Mail's 1 TB of storage and its former unlimited-storage offering.
