This feature is used when you need to notify individuals about various things, like being out of the office for a specified period of time or that an purchase has been received and is currently being prepared. The auto-responder e-mail also works as a confirmation for the people who get in touch with you their message is received, even if you are unable to read it and make contact with them at once. It could contain virtually any text that you choose and it may be edited depending on the precise occasion.
