To compare reports follow these steps:
- Select "Reporting" from the tool bar on the left.
- Click on "Emails" in the drop down.
- Click on View Reports to the right of an email that was sent.
- To compare multiple reports, click on the "Sent Email Reports" tab at the top of the page and select "View Reports" on a different email. With each report that you open, you will notice that the reports are collecting at the top of the page in new tabs, so you can easily switch back and forth between the email reports.
