I find it hard to believe that I cannot view the click-thru info for the web sign-up form when added to my Constant Contact emails. I emailed support about this and they said this reporting is unavailable. However, click-thrus to external sites are available, so surely a simple click-thru report on a Constant Contact form would be available too?
I guess the only solution is to create a new form every time I send out an email?! That seems silly, but I guess that's the only solution currently if I want to know which emails are driving sign-ups. Any other ideas would be greatly appreciated.
