### How are IMAP mailboxes (_aka IMAP Folders_) set up?
|
||||
|

`INBOX` is setup by default with the special IMAP folders `Drafts`, `Sent`, `Junk` and `Trash`. You can learn how to modify or add your own folders (_including additional special folders like `Archive`_) by visiting our docs page [_Customizing IMAP Folders_](../examples/use-cases/imap-folders) for more information.
