Currently, the Email Engagement feature only tracks email interactions when the primary recipient is an activity party such as a Contact, Account, or Lead. However, internal users (User entity) added in the CC field are not tracked, which limits visibility into internal collaboration and communication.

This idea proposes enhancing Email Engagement to support tracking when internal users are included in the CC field. Since customers often use the CC field to share emails with internal stakeholders, enabling tracking for the User entity in CC would ensure more comprehensive engagement analytics and better alignment with real-world email usage patterns.
