Thanks for bringing this up GS. The development team is actually in the process of creating World of Warcraft’s mail system.

Our mail system will be a little more robust than just sending in-game “emails” to friends. When completed, it will give players the ability to send packages to friends and will even be used as a sales tool; giving players the ability to send items C.O.D. (Cash on Delivery).

A mailbox will be located outside of any Inn and can be universally used by all, much like a bank teller. You click and get your mail; I click and get my mail.
