Push Email is free to use, and remote synchronization shows its power.

The synchronization of smartphones has brought great benefits to users, but being able to sync without a computer or server would bring even greater convenience. As for Push Mail, it is essential to mention BlackBerry, a service that was launched as early as 2001 in the U.S. and Canada. BlackBerry targets enterprise users who must first set up a dedicated server in their company in order to directly send corporate emails and calendar data from Outlook to the user's BlackBerry device. For Microsoft, which already owns the email server MS Exchange Server, real-time email services are undoubtedly a profitable business opportunity. Therefore, in 2006, Microsoft officially launched the Direct Push Email service to compete directly with BlackBerry.
