I have a question with regards to importing new leads to an existing static list. So, I have a static list which is synching with a SFDC campaign, but will need to add more leads to that static list as I go. I need these new leads to sync with the same SFDC campaign making sure only the new ones are added, with no duplicates... I hope this is clear.
Does anyone know if Marketo will add the previous leads to the SFDC campaign all over again along with the new leads added?
Thanks in advance for your help.
