How to Unsend an Email in Gmail

Is it possible to recall an email after sending? Gmail allows you up to 30 seconds to cancel an email once you’ve hit Send. To enable this Gmail feature, you need to go to Settings to set up Undo Send. An email can’t be stopped and will be sent once 30 seconds has passed.

Often the reason we want to unsend an email is for personal reasons. We may regret what we said in the email, realize we didn’t proofread it or we hit Send by mistake. 

Unless you realize your mistake within the first 30 seconds of sending the email, you won’t be able to stop it going out to the recipients mailbox. It’s also not possible to retrieve an email from another inbox once the email has been sent. 

Emails are sent using SMTP or Simple Mail Transfer Protocol. They are relayed from the clients email server (you) to the recipients email server before landing in their inbox. Unfortunately, unlike physical mail, there’s no electronic way to retrieve an email once it enters the system.

Unsend Hack: Use Gmail Confidential Mode 

If your concern is that your email may be copied, forwarded, printed or downloaded, then you may want to turn on Confidential mode before sending your email.

NOTE: If you’re using Gmail with a work or school account, be sure to clear this with your admin first.

By putting your email into confidential mode you won’t be able to unsend it but you will be able to limit how long your recipient can read it. You can choose 1 day to 1 week.  During that time the receiver won’t be able to share, print or copy your email.

You also have the option to revoke access to view the email at any time. If you send the email in confidential mode and then revoke access before your recipient has read it, it’s as good as un-sending it. 

  • Compose an email
  • In the bottom right window click the confidential mode icon (lock with clock)
  • Once the Confidential mode window pops up, choose when you want the email to expire from 1 day to 5 years
  • If you choose to require a SMS (text) passcode tick that box. To create enter your recipients phone # and they’ll get a passcode by text
  • Click Save

If you need to edit the email once it’s in confidential mode, go to the bottom of the email and click Edit

When your email recipient gets your email it will look like this.

In order to stop the recipient from reading the email, you’ll need to remove access ahead of the expiration time you selected. To do this, go to your Sent email folder in the left pane of Gmail.

Open the confidential email and click Remove access.

Your recipient will get a message like this when they try to open the message.

Keep in mind, that even if your email is in Confidential mode, once your recipient opens it they can conceivably snap a photo of the contents or attachments.

Of these major email providers, Gmail is the only one offering an Unsend feature.
