Hey all, we’re sending out emails with a button with URL variables.

The problem is that when I open an email that was sent to a lead, the variables are not parsed in the URL. Instead, the URL simply contains the custom fields like so _email={leadfield=email}_, etc.

When I test this by sending an email to myself or one of my colleagues, everything seems to work fine - the variables are parsed in the URL as intended.  
Any ideas what might be wrong?
