Email is the most important online service that we use today. Everyone has an e-mail account on Gmail, Yahoo, Rediff and Hotmail. It is your passport on the online space used to access to most apps and websites, but it’s often neglected. Today, in the year 2016, there is no business without e-mail accounts. Almost a majority of large enterprises, mid-size businesses, non-profit organizations, public administrations and small businesses have their email address that contains the name of their business.
