Overview
Have you ever tapped send and immediately realized something was wrong with your email? We have all been there. You can unsend an email on your iPhone if you recognize your mistake within a set time. This can save you a lot of embarrassment and the pain of having to write a follow-up correction email.
If you change your mind after tapping send on an email, iOS 16 and later has your back. If you wish to unsend an email that you sent via the Mail app, you have up to 30 seconds to do so.
Key Takeaways
- Learn how to take back an email you wish you had not sent.
- Avoid conflict, confusion, or embarrassment by unsending emails.
- Change the timeframe you have to unsend emails, from 10, 20, pr 30 seconds.
System Requirements

Unsend an Email
First, open the Mail app on your iPhone. Refer to the below image:

Next, draft an email and select a recipient; you can create a practice one to send to yourself. See the image below:

Now, tap Send. See the following image:

Next, depending on your iOS version, you will see an Undo Send button at the top or bottom of your phone. Tap it to stop the email from sending. Refer to the image below:

Now, after you stop the email from sending, your Mail app will open the draft again, so you can edit it and resend if necessary.
Tip: While this feature is new to the Mail app, other email apps, such as Gmail, have a longer unsending period.
If you wait longer than 10 seconds, you will not be able to unsend the email unless you change the Mail Undo Send Delay in your settings. You can unsend an email regardless of whether the recipient has an iPhone or is running the latest software.
Chande Mail Undo Send Delay Time
If you would like to give yourself some more time to unsend an email, you can do so in the settings:
First, open Settings. See the below image:

Next, in iOS 18 or later, tap Apps. See the following image:

Now, tap Mail. Refer to the image below:

Next, scroll to the bottom and tap Undo Send Delay. See the image below:

Now, you can pick between Off, 10 Seconds, 20 Seconds, and 30 Seconds. Tap one to select it. See the following image:

We like to do 30 seconds because it usually takes us a while to realize we made a mistake, so the more time we have, the better. We wish this could be even longer!
