An auto-responder email is a an e-mail that's sent from your mailbox as a reply to each and every e-mail that you get. The content is predetermined and it is sent automatically, so every individual that contacts you via email will receive it the instant their e-mail is received on the system that handles your e-mails. This function is used when you need to inform individuals about different things, such as being out of the office for a given period or that an purchase has been received and is currently being prepared. The auto-responder e-mail additionally operates as a verification for the people who get in touch with you that their message is received, even if you're not able to read it and make contact with them straight away. It can contain any text of your choice and it can be modified based on the precise occasion.
