Good idea and something we’re definitely looking for, our use case is:
I’m doing a workflow for new customers filling in a form on our website, so that an email is triggered from the responsible sales person based on the choices the customers make on the website form. However, the email that gets sent to the customer isn’t visible to the sales person unless they know where to look. Is there anyway to BCC the contact owner on the email to the new customer? So they can use the email to follow up if they don’t hear back for example.
