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.
Push email
Yahoo Mail may be pushed to an Android device, as Android now supports IMAP4 (as of September 2015). An alternative for Yahoo Mail is to install the free Yahoo Mail app, which provides instant push email. Numerous Yahoo users have complained that push does not function reliably; Yahoo has attributed this to server issues rather than the Smartphone app.
