## Default Mailboxes

Every new account starts with five mailboxes:

- **Inbox**: incoming messages
- **Sent**: copies of what you send
- **Drafts**: unsent messages
- **Trash**: deleted messages
- **Junk**: spam

These can't be deleted.

<note>

All incoming emails go to the Inbox. The other folders exist for IMAP client compatibility.

</note>

## Custom Mailboxes

Create additional mailboxes to organize messages by test run, environment, or client.

To create a mailbox, open an account in the [Mail](/mail/accounts) section and use the mailbox sidebar, or through the [API](/docs/api).

## Renaming

Open a mailbox's context menu in the sidebar to rename it.
