Hi!

My company just sent a direct mailer that had the signature's of multiple people. We are looking to do the same in a Pardot email and make sure the correct signature's match the mailer's we sent. My Salesforce Admin created a CRM user custom field to select the specific users the Pardot email will be sent from. However when we go to preview and put the sender as Propsect CRM User Custom Field it is not populating, instead the specific user is being used as the signature. Is there something we are missing? How do we get this to work? 

Thanks!

Sam
