By visiting the Reporting dashboard for your Email Campaigns, you can see which contacts on your email list opened your emails.
1. In the Global App Bar on the top of your Marketing 360 Dashboard, select Nurture.
2. Select the email campaign that you would like to view data for.
3. You will then see the reporting data for your campaign. You can select the links labeled Unique opens or opened so far to see which contacts on your email list opened your emails. A Unique open refers to each individual user who opened an email - if a user opens the email more than once, they will not be counted here.
