We just sent out a campaign, and the links to our site aren't working properly. Specifically the Google Analytics tagging is incorrect. Where there should be an ampersand, is a dollar sign:
This poses a problem to us because our application blocks any GET input with characters like that. It also poses a problem from a tracking standpoint, where utm_campaign isn't getting marked as a separate variable.
Please let me know when this is fixed or if the problem is on our end somehow.
Could you get in contact with firstname.lastname@example.org with your problem, and, more specifically, the campaign with which you're having the problem with, and we can fix it up for you.
Update: I got in contact with support. It was a problem on their end but they fixed it up quickly.
