It is a good practice to set up a holiday responder for your business mailbox in case you are going on a vacation/holiday and know that you won't have access to your mailbox. This way, anyone who sends you an email will get an automated and preset response.
You can access Vacation Responder from Settings > Preferences > Vacation Responder.
You can set the 'from' and 'to' dates, a custom subject line, and the message that you want to be automatically sent out to the sender. If you have contacts sending multiple emails to you, you can even control how frequently these contacts receive the auto-responder reply so as not to spam their inbox.
