I have a quick question. I set up a campaign in Marketo and I have set it up to not send to contacts within Salesforce. I only wish to send to leads. I have done this by applying the filter in the smart list of SFDC type is not contact. What I have found though, is that some contacts also have leads with exact same email address and details. These contacts ended up receiving these emails. Has anyone else encountered this problem before? Is the reason that the contact is receiving the email because there is lead? if anyone can help me answer this it would be greatly appreciated.
