An Autoresponder is a pre-determined message with information you want automatically sent to anyone who emails a designated email address/mailbox at your domain. When an email is sent to a mailbox that you have assigned an autorespond message to, the autoresponder automatically sends a reply. You can easily create an autoresponder with the WebControl System provided with your domain.
Example: Going out of town?
When someone sends you an email. You could have a Autoresponder say-
THANKS SO MUCH FOR YOUR EMAIL! :-) I am away, out of town, enjoying a long deserved vacation for the week of March 2nd. I will return on Monday March 14th. I do promise to promptly reply to your emails when I get home. ALTHOUGH I'M AWAY, I HOPE YOUR DAY IS FULL OF SUNSHINE! :) Always Yours, Jill
