As of September 2014, it is not possible to create a new RocketMail email account. Users who attempt to do so are directed to the Yahoo! website, where they are able to create email accounts under the "yahoo.com" domain.
RocketMail offered free email accounts in the 1990s, but it was acquired by Yahoo! in 1997. For over a decade, Yahoo! allowed previous RocketMail account holders to continue using their existing accounts, but users were not permitted to create new RocketMail accounts. In July 2008, Yahoo! changed its policy and allowed new users to create email accounts under the "rocketmail.com" domain. In April 2013, Yahoo! again changed its policy and stopped allowing users to create new "rocketmail.com" email accounts.
