Can I view email tracking history on any object?

When you send out a mass email via Campaign Monitor, we can create email tracking history records within Salesforce as long as your settings permit this (by default they do). An email tracking history record can be linked to a contact, person account or lead, matched via the standard email address field. On the contact or lead page layout, you can view our email tracking history-related list. Ask your admin if you don't have access.

The related list can't be added to objects other than contact or lead.  You can, however, add our Lightning component, which works on any object with an email field. The component surfaces data rather than storing it locally. To learn more, please see - https://www.beaufort12.com/campaignmonitor/support/email-tracking-statistics#Lightning-component
