Q. Tell me about emails.

A. - Mail can be checked by clicking the letter icon at the top right of the main screen, and it is divided into System, Territory, and Purchase categories. 

      - By default, mails are stored for up to 30 days, and  If not collected by the storage deadline, they will be deleted starting from the oldest.

※ Storage periods may vary depending on the type of mail.

※ When mails are deleted, attached rewards will also disappear. However, mails for purchased items will be stored.
