An auto-responder is usually a predefined message, that is sent automatically as a reply to each and every message received inside a mailbox with this feature enabled. The two most typical instances for taking advantage of this function are automatic emails that one is briefly out of the workplace or that an order is received successfully. An auto-responder can also be used as a basic confirmation that the email is received successfully, which is often something quite important in enterprise email correspondence. The message that's delivered can be pretty much anything and could be changed according to the conditions and what the auto-responder will be used for. As the function is activated server-side, there isn’t anything you are required to do by hand and you do not need an email application to be active constantly for the automatic reply to be sent to the individual sending you an e-mail.
