The key technical items required to set up during implementation are tracking code, email authentication, CNAME and IP whitelisting. Tracking code enables Marketing Cloud Account Engagement to track visitor and prospect activity on your website. Email authentication improves the deliverability and reputation of your emails. CNAME or vanity alias provides a seamless transition for your prospects when visiting pages and forms that you host on your site and Marketing Cloud Account Engagement hosted campaign elements. IP whitelisting allows you to restrict access to Marketing Cloud Account Engagement based on IP addresses.
