Hi @EMcGrath,
You can utilize the HubSpot Reporting feature. HubSpot provides valuable insights into user activities. To monitor the use of personilization tokens, you may want to consider creating a custom contact property specific to personilisation entries.
As team members populate the perosnalization tokens with additional text, you can use workflows or automation rule to update this custom property. Subsequently, you can run reports on the usage of these custom properties to track which team members are actively personalising content within the sequences.
Additionaly, you can go to HubSpot activity logs to see the history of changes made to contact properties.
By combinig custom properties, workflows and activity logs, you should be able to report and track.
Let me know if you have any follow-up questions.
