How To Unsend Email In Gmail: A Step‑by‑Step Guide

Everyone has sent an email and then wished they could take it back. In this Gmail tutorial, learn how to unsend an email in Gmail, whether you need to correct a typo, remove an attachment, or simply change the message content. Google’s “Undo Send” feature works like a short‑lived recall tool, giving you a window of time after you click Send to stop the message from leaving your outbox.

What Is “Undo Send” and How Does It Work?

The Undo Send function is not a true recall like in some corporate email systems; instead, Gmail delays the actual sending of your message for a few seconds. During this delay you can click Undo to cancel the send, edit the email, and resend it.

Enable Undo Send in Gmail

If the feature is not already active, follow these simple steps to turn it on:

  1. Open Gmail on a computer and click the Gear icon (Settings) in the top‑right corner.
  2. Select See all settings from the dropdown menu.
  3. In the General tab, locate the Undo Send section.
  4. Choose a cancellation period (5, 10, 20, or 30 seconds) from the dropdown.
  5. Scroll to the bottom of the page and click Save Changes.

After saving, a small “Undo” link will appear at the bottom left of the screen each time you send a message.

How To Unsend an Email in Real Time

Once the feature is enabled, unsending an email is straightforward:

  1. Compose your email and click Send as usual.
  2. Watch for the temporary notification bar that says “Message sent.”
  3. Within the time window you selected, click Undo on the right side of the bar.
  4. The email will reopen in the compose window, allowing you to edit, add, or delete content.
  5. When you’re ready, click Send again.

If you miss the cancellation window, the email is already on its way to the recipient’s inbox and cannot be retrieved through Gmail’s built‑in tools.

When the Undo period expires, consider these alternatives:
