There's also a publicly available Adobe UTM Campaign builder "Adobe UTM
Form Manager" that you can use. You'd need to configure your s.campaign
variable on your end to use it and finalize your classifications setup
but it's a good option to have. You will need to sign up for a
subscription to configure the form, form options, dropdown menus, etc
but it's a good place to start.
Here's a publicly available Adobe UTM Builder that can help you. It
requires that you set your s.campaign variable to cid and use the :
separator: Adobe UTM Form Manager. I’d recommend signing up for an
account quickly (instead of using the public "freemium" version to
customize your form options, track who builds the links users,
custom-brand the form, and have the company take care of all the needed
configurations when it comes to tracking your UTMs in Adobe. Pretty
quick and incredibly useful...
