If you're using a website analytics tool, like Google Analytics, you can generate UTM parameters within your account settings to append the URLs within your campaigns. Then you can check which links got the highest number of engagements within your analytics tool to see how your campaigns are performing.
![]() | Important: UTM parameters are added to the end of the URLs that are linked within the body of your email and SMS messages. They are not applied to the permanent URL for an email campaign. |
UTM parameters are added to the very end of the URLs within your campaigns, and are placed after the link tracking code that is included for your click reporting. If you share a link in several places around the web, the UTM parameters help you identify which location a click came from. Knowing where your clicks are coming from helps you to better focus your marketing efforts—lots of clicks indicate that the link is successful, but few clicks indicate the location isn't working and may need to be changed.
