In order to start using the Marketing application you need to ensure you are tracking your marketing traffic in Fortifi. In order to do this you need to configure your DNS Settings to ensure your tracking hostname is redirected to the CNAME url.fortifi.zone.
There is also an option within the Marketing application to provide your Publishers a Control Panel where they can log in and see and configure their Campaigns, view their own reporting and set their details such as Payment Details, Contact Details etc.
If you would like to offer the Publisher Control Panel you need to set your DNS settings to have your publisher hostname redirected to the CNAME publisher.fortifi.zone.
