How do I set up an autoresponder on cPanel?

An autoresponder replies when a message arrives at an address, for example to announce an absence. It is separate from marketing automation triggered by a purchase or subscription.

Prepare the message

Include a return date and an alternative contact if needed. Avoid unnecessary personal or internal details.

Create the autoresponder

In cPanel, open Email > Autoresponders.
Choose Add Autoresponder.
Select the relevant domain and address.
Enter the displayed sender, subject and reply text.
Set the interval between replies to the same sender and the start and end dates.
Save the settings.

Test the behavior

Send from an external address and check the reply. The interval prevents a reply to every message from the same person. An existing mailbox continues to receive messages normally.

After the absence

Check the end date or disable the responder. Some messages marked as spam do not trigger replies. Avoid loops between addresses with autoresponders or forwarding rules.
