The release of Salesforce Marketing Cloud in January 2020 introduced the Parameter Manager. This new addition facilitates the setup and modification of tracking parameters appended to your links within the Marketing Cloud, streamlining the management of your tracking links and eliminating dependence on support response times. What previously took days can now be accomplished in minutes.
Now, accessing the Parameter Manager is straightforward. Simply hover over your username in the top-right corner and select "Setup."
Once in Setup, navigate to "Data Management." You will find "Parameter Manager" listed at the bottom under the "Key Management" section.
