Hello,
I'm looking to see if there's a way for our form to pre populate with the leads information when they click to the form page from the email. Is this possible within Marketo?
Yes that should happen as long as the link is tracked and the landing page is a marketo-hosted landing page that has prefill enabled on the form.
You need to enable a checkbox in the form definition screen. Then it will pre-fill based on the cookie.
It's actually a drop down box called "Form Pre-Fill?"
Does the form page exist in Marketo or is it a non-Marketo landing page?
Yep, this is an out of the box feature for Marketo (as long as the record is known to Marketo)
