An auto-responder is usually a predefined e-mail message, which is sent automatically as an answer to each and every email received in a mailbox with this feature activated. Two of the most typical examples for taking advantage of this feature are automatic emails that one is temporarily away from the workplace or that an order is received successfully. An auto-responder could also be used as a common confirmation that the email has been delivered successfully, which may be something quite important in enterprise correspondence. The message that is sent can be pretty much anything and can be changed based on the situations and exactly what the auto-responder will be employed for. As the option is activated server-side, there isn’t anything you are required to do manually and you do not need an e-mail program to be active at all times for an automatic reply to be delivered to the individual sending you an email.
