To access mailbox in-game, press "B" or in the bottom right of your screen with the mail icon.
Mails are used to notify you when an item is sold on the marketplace as well as for house fame fund, guild incentives, and rewards.
Mails can only be received and cannot be sent to anyone.
A mail may contain silver or items in its attached item.
Items are received to your inventory and silver can be received to your inventory or received in the town's warehouse where you are located.
If you have already received an item (silver) or do not need the mail, you can delete them.
[All] selects all the mails on the current page, and [Delete] deletes the selected mails immediately.
