Have you ever hit the “Send” button too quickly and immediately regretted it? Many people wonder if it’s possible to unsend an email. The answer depends on the email service you’re using and how quickly you act. Here’s a detailed guide to help you understand when and how you can unsend an email.
Can You Unsend an Email?

Yes, but with limitations. Most modern email platforms offer a brief window to cancel or recall emails. However, once an email is delivered and opened, unsending becomes impossible in most cases.
How to Unsend an Email on Popular Platforms
Gmail (Undo Send Feature)
Enable Undo Send
- Open Gmail.
- Click the gear icon → See all settings.
- Under General, find Undo Send.
- Set the cancellation period (5, 10, 20, or 30 seconds).
Use Undo Send
- After sending an email, a pop-up saying “Undo” appears at the bottom.
- Click Undo within the time frame to stop the email from being delivered.
Outlook (Recall Email Feature)
Open Sent Email
- Go to Sent Items.
- Double-click to open the email.
Recall Email
- Click File → Info → Message Resend and Recall → Recall This Message.
- Choose to Delete unread copies or Delete and replace.
Important:
- Works only if both sender and recipient use Outlook with Exchange accounts.
- Recipient must not have opened the email yet.
Yahoo, Apple Mail, and Others

These platforms currently do not offer built-in unsend options. Always double-check before sending.
Alternative Methods to Manage Mistakes
- Send a Correction Email: Quickly follow up to clarify or correct errors.
- Enable Delay Send: Set up a rule to delay sending emails (available in Outlook and Gmail).
- Use Draft Mode: Review your email carefully before hitting send.
FAQs About Unsending Emails
Can I unsend an email after it’s opened?
No, once the recipient opens the email, unsending is no longer possible.
Does Gmail’s Undo Send delete the email from the recipient’s inbox?
No, it only cancels the delivery if you act within the set time window.
Can I recall an email sent to a different email client (like Gmail)?
No, Outlook’s recall feature works only within the same Exchange environment.
Can I delay sending all my emails automatically?
Yes, both Outlook and Gmail allow you to set rules to delay sending.
Are there third-party tools to unsend emails?
Some services offer delayed sending features, but none can unsend an email after delivery.
While unsending an email is possible under specific conditions and time limits, it’s always best to double-check recipients, content, and attachments before sending. Using features like Undo Send in Gmail or Recall in Outlook can help prevent embarrassing mistakes, but once the email is opened, it’s out of your control.
