I put the followin code into the email:
URL of the contact form was: [_url]
and it returns something like:
URL of the contact form was: http://my_addres.com/%23wpcf7-f1-w3-o1 which is not a page but 404 page. I have my contact form installed in footer on every page of the website and I'd like to track submissions but I get strange results!
