Duplicates in Marketo and how to Handle Them What are Duplicates? - Email
Marketo recognizes duplicates as two or more person records that share the same email address.
So, if someone is filling out a form online and they utilize the same email address as someone else, we'll call them Sharon, all of their information (besides the email address) is going to update Sharon's record.
This can become an issue during situations, for example, where you're utilizing a kiosk for form fills such as at a trade show. Instead of adding dozens of new leads to your database, you'll end up getting just the one (and it will be the final person that filled out that form.)
