How to Unsend an Email in Gmail

July 14, 2025

Did you send an email by mistake or change your mind right after clicking Send? Good news! Gmail offers a feature called "Undo Send" that allows you to cancel an email after accidentally clicking "Send," provided you do so within a certain time frame. Learn right now how to unsend an Email in Gmail :)

Can You Unsend an Email in Gmail

Gmail allows you to cancel sending a message through its "Undo Send" feature. It appears by default between 5 - 30 seconds after the email is sent, and you can set it both on your computer and in the mobile app. Even if, this feature does not retrieve the email if it has already been delivered, it delays the sending for a few seconds to give you the option to cancel it.

You can set the cancellation time frame in your Gmail settings

  • Minimum: Five seconds
  • Maximum: Thirty seconds

Once this time has passed, unsending the Gmail message won't be possible.

  6. This is how to unsend email Gmail.

💡 You can set the time limit for undoing sending:

  • Go to Settings (look for the gear icon) > See all settings.
  • In the "Undo send" section, set the time to unsend the email: 5, 10, 20, or 30 seconds.

How to Unsend an Email on Gmail from the Mobile App

  1. Open the Gmail app on your Android or iOS
  2. Send an email as usual.
  3. Immediately after sending it, a bar will appear at the bottom of the screen with the options: "Undo" and 'View'.
  4. Tap "Undo".
  5. The email will be instantly canceled and the message will return to the editing screen.

What Is the Undo Send Feature in Gmail

  • Through "Undo Send", you can cancel the sending of an email only a few seconds after you have sent it. 
  • However, it does not recover a message that has already been delivered, but rather creates a time lag between when you click the option "Send" and when the message is sent :) 
  • This is a safe zone to avoid mistakes, such as: Incorrect recipients, subject lines, wrong attachments, or messages written in the heat of the moment. Since the message does not leave the Gmail server until the timeout ends, you can stop it from being sent.

🕒 The time you choose is the maximum period during which the 'Undo' option will appear each time you send an email.

How to Test and Optimize Undo Send Window for Your Needs

We recommend the following tips:

  • Do a test: Send a test email or draft to your own email address and use the "Undo Send" button to verify that it works correctly.
  • Choose carefully: If you typically review your emails after sending them, selecting a 20-second window may be sufficient. If you prefer to take your time, select 30 seconds.
  • Take into account your devices: Remember that the time limit you set in your browser will also apply to the app.
  • Make it a habit: There is no rush. After sending a message, wait a few seconds without closing the tab. This gives you time to catch a mistake and manage better.

⚙️ Keep in mind that this feature does not replace proofreading, but it does add a useful layer of security to prevent impulsive or technical errors.

Can You Unsend an Email on Gmail: Alternatives If You Can't 

If the time to use "Undo Send" in Gmail has passed, or if you didn't have it enabled, you won't be able to cancel the email. However, here are some recommendations:

  1. Avoid repeating the same mistakes: Enable the "Undo Send" feature and set the maximum time allowed.
  2. Send an email to clarify: If you made a mistake, reply to the same thread as soon as possible with a clear explanation. 
  3. Request to ignore or delete: If the email was sent to the wrong email, ask them to ignore or delete it. This does not guarantee they will do it, but it is a responsible action.
  4. Schedule your emails: Ensure that you send the correct information at the right time.
  5. Revoke all shared access: If you sent a file from Google Drive or Dropbox, revoke access to the document.

📩 Although you can't always delete what you've already sent, act fast to maintain clear and reliable communication.

FAQ

Can you unsend a Gmail message after 30 seconds

No. Once the seconds configured for the "Undo Send" feature have passed (a maximum of 30 seconds), the email is sent permanently and cannot be recovered or canceled.

⏱️ Make sure you have the maximum time available enabled in your Gmail settings.

Does Gmail have options to recall an email in Gmail after it's delivered

Not exactly. Gmail does not offer recall of sent emails beyond the undo function. Once the mail has been sent, there's no way to remove it from the recipient's mailbox. The only alternative is to send a clarification email.

Does Deleting an Email Unsend It

Deleting an email from your sent folder does not cancel its delivery. The message has already left the server and is in the recipient's inbox. Deleting it only removes it from your inbox, not from the Gmail system or the other user's mailbox.

Can I Unsend an Email in Gmail After It's Been Delivered

Only if you select the Undo Send window to 30 seconds. After that time passed, deleting the email from Gmail is no longer an option, as it is considered permanently sent.

💡 Check your message carefully before sending it. Or use "schedule send" if you need more control.

Why Can't I Unsend an Email in Gmail Sometimes

There may be several limitations:

  • You don't have the "Undo Send" feature enabled.
  • You have set a very short time limit (5 seconds by default).
  • The time limit has expired when you tried to cancel.
  • The network or browser did not load the button in time (on slow devices or unstable connections).

Solution: Enable the feature from "Settings > General" and select 30 seconds as the maximum time limit.
