"Push e-mail is used to describe e-mail systems that provide an "always-on" capability, in which new e-mail is instantly and actively transferred (pushed) as it arrives by the mail delivery agent (MDA) (commonly called mail server) to the mail user agent (MUA), also called the e-mail client. Most of today's clients are smartphones."

Good ol' Wikipedia

The mail gets pushed to your phone right when it is sent to you as opposed to you pressing send/receive and seeing if there is any mail.

Essentially, you get an email alert as soon as you receive an email.
