The Macro Content Suggestions EAP is currently available to customers on any plan with Support Enterprise. As the suggestions at this stage are sent out on email, we also require that it's a Zendesk Support Admin, who registers for this EAP through this EAP sign up form. 

We cannot guarantee that everyone can join at this stage, but we’ll do our best to support as many as possible. We look forward to working with you on this exciting new feature!
