Tracking Offline Marketing Campaigns

Hey guys,
I’m doing an offline campaign that I want to track on my site. I’d like to mask the URL with all the UTM info in it so that the flyer can look more like mysite.com/flyer.

I believe the best way to accomplish this is to use a custom URL and redirects. My thought was to use subfolders on the site for each unique URL, and have visitors redirected to our main page. This way I can still track the individual channel they used to get there.

Would anyone please let me know how I can do this in Webflow?

Thanks in advance!!!
