Unsend emails with Undo Send in Mail on Mac
If you’ve made an error in your email or sent an email by mistake, you can recall an email with Undo Send. You can also set a delay for all emails to give yourself a little more time to unsend them.
![A Mail window showing the sidebar on the left. The Undo Send button is at the bottom of the sidebar.](https://help.apple.com/assets/63CF0773EF8ABA61CC409172/63CF077AEF8ABA61CC40917A/en_US/d32a7208c712a53d926bf92cdcab9757.png)
In the Mail app
on your Mac, click Undo Send at the bottom of the sidebar within 10 seconds of sending an email (or choose Edit > Undo).
Note: To change the amount of time you have to unsend emails or to turn Undo Send off, choose Mail > Settings, click Composing, click the “Undo send delay” pop-up menu, then choose an option.
