An autoresponder in web hosting and email marketing is a program that automatically sends a predefined response to emails sent to a specific email address. It is often used for out-of-office replies, customer service acknowledgments, and email marketing campaigns. Autoresponders can be simple, sending a single response to all incoming messages, or complex, providing tailored responses based on the content of the incoming email. They help in managing customer expectations and maintaining engagement even when a personal response is not immediately available.
