Your D9 Hosting account allows you to set up autoresponder messages for all of your email addresses.
Whether you want to automatically respond to your emails with a brief email reply such as "Thanks for your message. I'm away from the office currently but will be in touch soon", or whether you want to respond in more detail, you can set this up quickly and easily through your cPanel
1. Locate the Email section
2. Click on the AUTORESPONDERS link
Please note that the autoresponders CANNOT be used to send a sequence of autoresponder messages from an email address. For this you will need to subscribe to a service such as Aweber or GetResponse
