2 A Marketing Interaction is a personalized message sent to any entity, such as a contact, lead, account, or Customer Insights profile, using Customer Journey Orchestration (real-time marketing features). The message can be sent through out-of-box channels available in Dynamics 365 Marketing (for example, email, web-form submissions, push notifications, event check-ins, LinkedIn), external channels (for example, SMS providers), or third-party systems integrated with Dynamics 365 Marketing.
