Be able to see whether a person has viewed the email we sent them.
This could be by having a green tick next to the email we have sent them - once they have read it. Also, if they viewed the email, but chose to not reply this should be represented with a red tick next to the email we have sent them. It makes it less frustrating that way.
This should be for all devices - iOS, Android, Windows etc.
