Shiva Ayyadurai
In 1994, Ayyadurai founded a company called Millennium Cybernetics, which produces email management software originally called Xiva and now called EchoMail. The software analyzes incoming email messages to organizations before either replying automatically or forwarding it to the most relevant department. By 2001, customers included Kmart, American Express, and Calvin Klein, as well as more than 30 U.S. senators to help handle constituent email. EchoMail competed with more established customer relationship management software that had an email component. On its website, EchoMail describes Ayyadurai as the "Inventor of Email".
