This is a nice way to automatically respond to certain emails you get so that you can contact your prospects in your affiliate program, for example, with those emails saying "is a new prospect" as part of the subject line. This keeps the prospect engaged and hopefully induces them to continue the conversation. You can just send them a short email where you introduce yourself and offer to help if they have any questions.

Click on Settings > Labs. Scroll down to Canned Responses (about halfway down the page). Click Enable. Scroll to bottom, click Save Changes.

Click Compose Mail. Select New canned response in drop-down menu. Name it.

Create a message. Example:

Hi there. My name is... and I notice that you visited my web site. Please let me know if you have any questions. I'm here to personally help you however I can.

Thanks.
(Your name here)

Select Save (message name) in the Canned responses drop-down.

Discard message.

Click on Settings > Filters > Create a new filter

Paste common text from subject of new prospect notice from GDI, e.g., "is a new prospect" into Subject field.

Click Next Step. Choose canned response from drop-down. Check Send canned response and click Create Filter.

you can use this auto response for any program you get leads from that emails you with a default message "new prospect" etc. as long as the sending email address is of your leads email address  because your lead should be the one to receive the pre-written or canned response eamil.
