You can send and receive mail from other places in IdleMMO.
Sending mail to others is a great way to communicate with your friends, guild-mates, or other players.
Sending mail is not a free service. The cost of sending mail depends on how far away the recepient is from you. The further away the recipient is from you, the more it will cost.
If you are in the same location at the recipient, the cost is completely free.
All content sent through the mail system is subject to moderation. This is made clear to all participants. Any messages violates the game's Code of Conduct or guidelines may be removed, and the sender may face penalties.
