Yahoo! Mail is an email service launched on October 8, 1997, by the American company Yahoo, Inc. It offers four different email plans: three for personal use (Basic, Plus, and Ad Free) and another for businesses. As of January 2020, Yahoo! Mail has 225 million users. Users are able to access and manage their mailboxes using webmail interface, accessible using a standard web browser. Some accounts also supported the use of standard mail protocols (POP3 and SMTP). Since 2015, users can also connect non-Yahoo e-mail accounts to the webmail client. Source: https://en.wikipedia.org/wiki/Yahoo!_Mail
