# How do I find the biggest emails in Apple Mail?

In Mail, select a mailbox and choose **View → Sort By → Size**, then sort descending to see the largest messages first. Repeat for big folders like Sent and Archive.

Delete or archive large messages you don't need, then choose **Mailbox → Erase Deleted Items** to free the space. For IMAP accounts this also removes them from the server, so save attachments you want first.
