How to Unsend an Email in Gmail
To unsend an email in Gmail:
- Send your email.
- Look at the bottom-left “Message Sent” notification.
- Click Undo within 5–30 seconds.
- The email will reopen in draft mode.
That’s the fastest way to unsend an email in Gmail.
What Does “Unsend” Actually Mean in Gmail?
Before understanding how to unsend an email in Gmail, you must know something important.
Gmail does not truly recall an email after it reaches the recipient.
Instead, Gmail delays the sending process for a few seconds. If you click Undo, Gmail simply stops the email before it is delivered.
This is called the Undo Send feature.
Many people confuse “unsend” with “recall email in Gmail,” but they are technically different concepts.
