To review email engagement, Inbox provides email metrics directly within Outlook. These are the same metrics provided in the Activity Manager.
Option 1: View via Summary Email
Select the summary email you received after sending the mass email and open the Inbox add-in.
The Email Metrics section will appear, showing you an overview of engagement.
Option 2: View via Sent Items
Navigate to your Outlook Sent Items folder.
Click on the mass email you sent and open the Inbox add-in.
This will show the same Email Metrics section.
Note: If you do not see a specific metric here like Unique Links clicked, contact us or your administrator to enable it.
