We are currently facing an issue in our Lead Database of many records without SFDC Id's. This is an issue because account owner fields are not pulled into Marketo so when we send an email out in the Account Owners name it does not populate or update.
Some cases we are pulling records from Salesforce and into Marketo through the smart campaign smart list criteria. Other instances we are importing a list into Marketo, which does not import the SFDC if it is a new lead. How is everyone else handling this issue? Is the only way a SFDC ID can be carried with a record into Marketo when it is pushed down from Salesforce to Marketo?
