Have you ever regretted an email immediately after you’ve sent it and wish you could grab it back from the ether before it gets to your recipients? We all have. And here’s the good news: you can.

Both Gmail and Outlook let you unsend an email for a short period of time after you hit the send button, but the trick is you need to have the feature enabled first. Once enabled, “Undo Send” will allow you a brief window when you can successfully retract your message before it reaches its end destination. The “Undo Send” feature doesn’t retrieve your email from other people’s inbox; it merely delays sending your email, giving you the chance to change your mind before it’s too late.

How to unsend an email in Gmail

Gmail’s “Undo Send” feature is automatically turned on, but you can adjust the period of time that emails are held from the default of five seconds up to 30 seconds. I have mine set for 20 seconds – pick whatever feels best for you.

To adjust your timeframe, go to:

  1. Gmail Settings (cogwheel icon) > See all settings > and choose the General tab.
  2. Scroll down to “Undo Send.”
  3. Set the “Send cancellation period” to whatever is most works best for you – 5, 10, 20, or 30 seconds.
  4. Scroll all the way down and click on the “Save Changes” button.

How to “recall” a message in the desktop version of Outlook

Outlook has a “Recall Message” feature that can delete an email sitting in the recipient’s email inbox. However, it only works if you are sending a message to someone using the same Microsoft Exchange server (i.e., someone within your company) or to another person with a Microsoft 365 account. So, you’ll still want to set up “Undo Send” for all of your other email. You’ll find the directions in the next section, “How to unsend an email in the desktop version of Outlook.”

To recall a message in Outlook:

  1. First, check to see if your message is still in your “Outbox.” If you have just hit send, it’s likely that the message is still in your “Outbox.” If it is, you can drag the message into your “Drafts” folder or delete it.
  2. If your email has been sent, you’ll find it in your “Sent” folder.
  3. Double click on the message you want to recall. The message will open in a pop-up window.
  4. Under File > Info > Message Resend or Recall, select “Recall This Message.”

If you use the desktop version of Outlook, unsending an email works in a different way from the online version of Outlook.
