It would be really helpful if it would be possible to distinguish between test eDMs and real eDMs. Also the market each eDm relates to. At the moment this is  not possible  which means recipients don't know if they are receiving a test email to comment on or the real thing. It would save people time, effort and cross wires if this was clear on the emails. Also, when working globally but within markets with the same language it would really help to know which email relates to which market as although the language may be the same there can still be differences due to regions. It would also be very helpful to ensure which marker the emails relate to. If you are sending out several emails in English you have know idea which is which- which have worked and which haven't and which to edit appropriately.
