I just did a workflow where when an email is sent, it is creating a task as a follow up in SFDC for the sales rep. The problem is that the task is not actually assigned to a contact, lead or account in Salesforce. The "Related To" field at the task level is empty. This means that my reps can't tell the difference between tasks for different contacts that received the email. Did I set something up wrong? I just assumed that the related to would have matched the contact that received the email.
