Automessage and Gravity Forms


At the moment I am using gravity forms for a client to fill out in the front end, when they submit it an intro message gets sent to them with the prices we offer. I would like to keep the same functionality where they fill in the form on the front end, but style the message that gets sent to them and then 3 days after an automatic follow up message gets sent to them. Is it possible to use Automessage along with Gravity forms? Or do I have to create a new form in Automessage? And are we able to style the message that gets sent?
