Email Notification is a type of communication that is sent electronically to alert the recipient of an event or message. It is typically used to inform people of important updates, such as new emails, upcoming events, or changes in policy. Email Notifications can be sent to multiple recipients at once, making them an efficient way to communicate with large groups of people. The term 'SENT' is an acronym for Simple Electronic Notification Technology, which is a system used to send and receive email notifications.
