    Uploading a static list without overwriting current contact

    Kevin Caballero

      Question is essentially stated above. I want to be able to upload a list of individuals that attended one of our events. I want to make sure though that if the person already exists in Marketo though that we are not overwriting their information. How do I upload the list without making a list of current Marketo contacts?
