I understand that the sync between Salesforce and Marketo keys off of email id of the leads. But, is there any other field which I use as the primary key for this sync? Is this modifiable? I was looking for SFDC record id, which will be unique, even if there are multiple leads/contacts with the same email id in salesforce. Can I change this sync to key off sfdc record id? or something besides email id? Because we have a situation where the email id for is the same for 3 different accounts, and it keeps updating only one lead. How do I stop this?
Thanks in advance!
