Hi @John I came across this thread and we are having a very similar issue. I am passing just the email parameter to test from a hubspot form to a wordpress page (that includes the HubSpot tracking cod) . First line is the parameter they way i have it in the redirect and then the second is how it actually comes out. Any suggestions?
?email={{contact.email}}
email=%7B%7Bcontact.email%7D%7D
Basically I am trying to follor the directions in this article but it does not seem to pass the parameter.
