Yahoo! Mail is an email service launched in 1997 by the American company Yahoo!, now a subsidiary of Verizon. 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 had 225 million users.[7
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.
For many years, users were able to open accounts using either ''@yahoo.com'' or a national domain (''@yahoo.fr'' in France, ''@yahoo.co.uk'' in the United Kingdom,''@yahoo.it'' in Italy, etc.). Currently, Yahoo! only allows users to register ''@yahoo.com'' accounts.[9
Yahoo! made a deal with the online communications company Four11 for co-branded white pages. Marvin Gavin, who worked at Four11 as the director of international business development, said "We always had a bias about being acquired by Yahoo. They were more entrepreneurial than Microsoft. We had a great cultural fit – it made a lot of sense." In the end, Yahoo! acquired Four11 for $96 million. The purpose behind acquiring Four11 was the company's RocketMail webmail service, which launched in 1997. Yahoo! announced the acquisition on October 8, 1997, close to the time that Yahoo! Mail was launched. Yahoo! chose acquisition rather than internal platform development, because, as Healy said, "Hotmail was growing at thousands and thousands users per week. We did an analysis. For us to build, it would have taken four to six months, and by then, so many users would have taken an email account. The speed of the market was critical."[This quote needs a citation]
The transition to Yahoo! Mail was not easy for many Rocketmail users. On March 21, 2002, Yahoo! eliminated free software client access and introduced the $29.99 per year Mail Forwarding Service. Mary Osako, a Yahoo! Spokeswoman, told CNET, "For-pay services on Yahoo!, originally launched in February 1999, have experienced great acceptance from our base of active registered users, and we expect this adoption to continue to grow."
