Hello. When I create a Customer Journey in Dynamics 365 Marketing, I would like to create a condition that will allow me to continue a journey depending on whether or not a contact responded to an email. Currently, I see that available conditions include whether or not the email has been opened, a link has been clicked, etc. But there is no condition for whether or not the email has been responded to. Is there any way to determine whether a contact has responded and create a condition based on it? Thanks!
