Collecting data on a form but only using if it doesn't already exist on the lead
We have a Marketo form with first name, last name and email address fields. Is it possible for the form to accept a first and last name but only use that data if it doesn't already exist on the lead?
We have a business use case where we want to be able to send the name for associating with new leads, but would like to avoid changing the name of a lead if the same email address is used for multiple people.
