There are built-in tools that allow you to track how individual campaigns are doing. This will show you how many times an email was opened, clicked on, bounced, and unsubscribed. For more in-depth information about how your campaigns are doing, we recommend using Google Analytics. You can sign up for a Google Analytics account for free at google.com/analytics.
To enter the tracking code provided by Google Analytics, click on the marketing icon, then hover over settings and click on analytics.
From there, paste the tracking code into the box provided and click on save changes.
