Private mailing system

I propose that there should be a mailing system where you can send messages privately to any clash of clans player and vise versa. I find it so hard to constantly communicate to anyone. Because in order to talk to any player, the player has to be on chat and sometimes when I am offline, the player is online. And everything you message goes public either in global chat or clan chat. I can never have a private conversation with a player because of this. So I propose there be a mailing system so I communicate with anyone even if they are offline privately.

searching for players is already ruled out

Would like to see the ability to send predetermined messages to other members. Such as. Come back to clan, nice attack, tough defense, revenge soon. Ect.
