I created an email with a CloudPage button link. We will have different emails leading to this cloudpage which contains a smartcapture form, but I want to track which email drove the subscriber to the smartcapture form.
I thought adding a constant AMPscript variable to the email would allow me to ID that email and pass the constant variable to the hidden smartcapture field. But, that value is not carrying over. However, all the target DE fields for the subscriber are pre-populating just fine on the form (i.e. first name, Last Name, Email). Here's What I've set in the email:
%%[ var @EntrySource set @EntrySource = "Email 1" ]%%
And here is what i placed in the smart form field value:
Is it not possible to carry these constant variables to cloudpage form fields when setting a link destination to a cloudpage?
