That's a great question! This reporting can be found under the Reporting tab of your account.
This is where you can scroll down to the Email Campaigns section and locate the campaign you are working with. Each email sent in your account will display in this section with columns for each break-down in reporting including these bounces. Clicking on this hyperlinked number, will bring you to view all of this email’s stats. Then from the drop-down on the left-hand side, you can select to view its bounces. From this page you also have the option to use the Export Report button to download and save a report as an Excel or CSV file to your computer.
