How To Unsend Email In Gmail After An Hour

by

The ability to unsend an email in Gmail can be a lifesaver, especially when you’ve sent an email by mistake, left out important information, or simply changed your mind about the message’s content. However, by default, Gmail only gives you a 30-second window to retract your email. What if you realize an hour later that you need to unsend an email?

Unfortunately, Gmail does not have an in-built feature that can unsend an email after it’s been more than a minute after it’s sent. Despite this, worry not! We have a workaround that entails using “delay send” function in Gmail which will allow you to effectively ‘unsend’ an email up to an hour (or more) after you hit the send button.

Using Gmail’s ‘Delay Send’ Feature

This feature is not exactly an ‘unsend’ option, but rather a delay in the sending of the email. This gives you ample time to change your mind and stop the email from ever leaving your outbox.

Here’s how to set it up:

  1. Log in to your Gmail account on your computer.
  2. Click on the Gear icon in the upper right corner to access your settings.
  3. Select See all settings.
  4. Go to the General tab.
  5. Scroll down to ‘Undo Send’.
  6. In the ‘Send cancellation period’ section, set the cancellation period – this can be 5, 10, 20, or 30 seconds. Unfortunately, Gmail does not currently allow a delay longer than 30 seconds via this method.
  7. Scroll down to the bottom of the page and click Save Changes.

If you want to delay the send for more than 30 seconds, you can use third-party extensions or Google Scripts.

Using Third-Party Extensions

Extensions like Boomerang for Gmail and Right Inbox provide a “send later” feature that can be set for a specific time — up to several days later. So, you can write an email, set it to be sent in an hour, and if you change your mind within that hour, you can stop it from being sent.

Using Google Scripts

Another way to delay sending your emails is by using Google Scripts. Google Scripts allows you to set up a script that delays all outgoing emails by a certain amount of time. It’s a bit more complicated than the previous methods, but it’s a reliable way to ensure you always have a chance to unsend your emails.

Here’s a simple script that delays all outgoing emails by 1 hour:

function delaySendEmails() {
  var threads = GmailApp.search('label:inbox is:unread');
  for (var i = 0; i < threads.length; i++) {
    var messages = threads[i].getMessages();
    for (var j = 0; j < messages.length; j++) {
      if (messages[j].isInTrash()) {
        continue;
      }
      var body = messages[j].getBody();
      var subject = messages[j].getSubject();
      var to = messages[j].getTo();
      GmailApp.sendEmail(to, subject, body, {name: 'Your Name', noReply: true});
      Utilities.sleep(3600000); 
    }
  }
}

This script will search for unread emails in your inbox and send them one by one, with a delay of one hour (3600000 milliseconds) between each email. To use this script, you need to replace ‘Your Name’ with your name.

Please note that messing around with scripts should be done with care, and only if you’re confident in what you’re doing.

In conclusion, while you can’t directly ‘unsend’ an email in Gmail after an hour, there are workarounds available that give you the next best thing. Using delayed sending or scheduling your emails gives you the opportunity to prevent an email from being sent out, even if you change your mind after pressing ‘send’.
