I think you meant to ask "How to use Gmail's Undo Send feature?"

Gmail's Undo Send feature, also known as "Undo Send" or "Take Back Send," allows you to retract an email you've sent within a short period of time after sending it. Here's how to use it:

Enable Undo Send:

1. Log in to your Gmail account.
2. Click on the gear icon in the upper right corner of the page.
3. Select "See all settings."
4. Scroll down to the "General" tab.
5. Look for the "Undo Send" option and toggle the switch to the "On" position.
6. Choose the time frame for which you want to be able to retract your emails (5, 10, 20, or 30 seconds).

Use Undo Send:

1. Compose a new email as you normally would.
2. Click the "Send" button.
3. Immediately after sending the email, you'll see a notification at the top of the page that says "Undo" or "Cancel."
4. Click on "Undo" to retract the email. You'll see a confirmation message that the email has been successfully recalled.
5. If you don't see the "Undo" option, it may be because the time frame for Undo Send has expired.

Note:

• Undo Send only works for emails sent from the Gmail web interface. It doesn't work for emails sent from the Gmail mobile app or other email clients.
• Undo Send is not foolproof, and there's a small chance that the email may still be delivered to the recipient's inbox before you can retract it.
• If you're using Gmail's "Send and Archive" feature, Undo Send will not work.

I hope that helps!
