Unable to add existing leads to nurture via custom form
Relative Marketo newbie here. We are trying to run a Nurture with new and existing leads being fed into Marketo via a custom form from a website. We are working with an outside vendor on the site and the form. The problem that we've noticed in testing is that existing Marketo leads are not being appended with the custom URL passed via the form and thus are not being added to the nurture/entering the flow. However, everything is working fine for new leads (who were not in Marketo prior to filling out the form). Thanks for any suggestions.
