Create or delete mailboxes in Mail on Mac

Any email account you use in Mail has a set of standard mailboxes—Inbox, Sent, Drafts, and Trash. You can create your own mailboxes to help keep your email organized. For example, you could create a Book Club mailbox, with mailboxes inside it to organize messages by author or genre, and then move messages to one of the mailboxes.

The Mail sidebar showing standard mailboxes (such as Inbox and Drafts) at the top of the sidebar and mailboxes you created in the On My Mac and iCloud sections.

Tip: If you want to organize messages without moving them around, use Smart Mailboxes.
