Seen that @AmyF hasn’t replied here, but from my perspective I do agree that being able to see if someone has replied to a marketing email send through at least Pro / Enterprise. It would be great to see the reply, but if not possible, at least to show whether a reply has been received by the marked sender. Often we send emails where the goal or CTA is for the recipient to reply, and being able to report on this would be valuable, without having to ask sales teams, MD’s etc if they received a reply. Understandably, a limitation here would be that out of office replies would probably count, which wouldn’t be so good.
