Question

Contacts being duplicated after CSV file upload

We have noticed that contacts are duplicated in Marketo and SF when we upload a CSV list of contacts to invite to an event.

Some of the contacts will already be in our database (both in SF and Marketo), however, Marketo will sometimes duplicate the contacts which then leads to a duplicate also being created in SF.

Is there a way to prevent this from happening going forward, so that existing contacts are not duplicated?

To be clear: do you mean multiple Marketo persons with the same email address? It's important to know exactly what you mean by "duplicate."

Same person, with the same email address

Are you positive that the email address does not have leading or trailing spaces in the CSV for the affected people?
