Hello! I created an engagement program in Marketo where we will be sending direct mail postcards to leads and directing them to a landing page in Marketo where they can download a whitepaper by first filling out a form. I have tested the process using dummy leads but those leads are not syncing over to Salesforce. I am sure I am missing a step in the process, but have been unable to identify what that might be. Any suggestions? Do I need to include it as a campaign flow step?
