We’ve all been in the situation where we’ve sent emails too quickly, only to realize we forgot an attachment, sent it to the wrong person, or made a typo in the subject line. Fortunately, most modern email services now include an “unsend” or recall feature that can save you from embarrassing or costly mistakes.
In this article, we’ll cover how to unsend an email on popular platforms like Gmail and Outlook, explain the limitations of the feature, and share tips to avoid future email mishaps. Kindly read attentively.
Is it Really Possible to Unsend an Email?
The short answer is yes, however, this comes with limits. Usually, once an email is delivered to the recipient’s server, it’s usually out of your control.
Email 706376 “unsend” features don’t technically delete the message after delivery. Instead, they delay sending for a few seconds (a grace period), giving you a chance to cancel it before it leaves your outbox. In some cases for instance, with Microsoft Outlook in corporate environments, there are special recall tools that attempt to pull back an already sent email, but they don’t always work.

How to Unsend an Email in Gmail
Gmail offers one of the easiest unsend features by using a short “Undo Send” window.
See Steps below:
Enable Undo Send (if not already active):
Open Gmail.
- Click the gear icon (⚙) > See all settings.
- Under the General tab, find Undo Send.
- Choose a cancellation period: 5, 10, 20, or 30 seconds.
How to Use It When Sending:
- After hitting Send, look at the bottom-left corner of your screen.
- You’ll see an “Undo” button appear.
- Click Undo within your chosen timeframe.
- The email will reopen in draft mode so you can edit or discard it.
This is best for: Quick corrections, typos, wrong attachments.
Limitation is that you can only unsend within the cancellation window.
How to Unsend an Email in Microsoft Outlook
Outlook offers two different features depending on whether you’re using the desktop app or Outlook on the web.
Outlook for Web (Undo Send)
- Click the gear icon (⚙) > View all Outlook settings.
- Go to Mail > Compose and reply.
- Scroll down to Undo Send and choose a delay (up to 10 seconds).
- After sending an email, you’ll see an option to Undo within that time frame.
Outlook Desktop App (Recall Feature)
- If both you and your recipient use Outlook with a Microsoft Exchange account, you can attempt to recall a sent email.
Steps:
- Open Sent Items.
- Double-click the email you want to recall.
- Go to Message > Actions > Recall This Message.
- Choose to delete unread copies or replace with a new message.
Best for: Corporate environments where everyone uses Outlook + Exchange.
Limitation: Recall only works if the recipient hasn’t opened the email yet. It also doesn’t work with external email providers (like Gmail or Yahoo).
How to Unsend an Email in Apple Mail (macOS Ventura or later)
Apple introduced an Undo Send feature in Mail for macOS Ventura and iOS 16.
Steps:
- After sending, look at the bottom of the Mail app.
- You’ll see Undo Send appear for about 10 seconds.
- Click it to stop delivery and return the email to drafts.
- Works seamlessly if you’re in the Apple ecosystem.
- Limitation: Short cancellation window only.
Tips to Avoid Sending Emails You’ll Regret
- Enable Undo Send with the maximum delay available.
- Double-check recipients before sending, especially group emails.
- Attach files before writing your message so you don’t forget.
- Preview your email (many apps have this feature) before hitting send.
- Use drafts for important messages—take a break, then re-read before sending.
Conclusion
Unsending an email isn’t magic but more like hitting pause on delivery. Gmail, Outlook, and Apple Mail all offer short cancellation windows, while Outlook’s recall feature can sometimes pull back a message in certain environments.
The best practice is to set up your email client with a delay and always review messages before hitting send. That way, you’ll reduce mistakes and avoid resending emails or embarrassing moments.
Since technology keeps advancing, there is the prospect that in future, something more advanced could be done about this. We’ll be sure to update you when the time comes.
