The Mail app gives you a few seconds to unsend an email.

As an iPhone user, you may not realize this, but you can now unsend an already-sent email. It's an excellent option to have in case you send an email to the wrong person or if you made some bad grammatical mistakes you need to fix.

The feature, which is new to iOS 16, works with the built-in Mail app and gives you a limited amount of time to recall a sent message, whether you're using iCloud, Gmail, Outlook or Yahoo.

Before you try to unsend an email

For this feature to work, you must use the Mail app for sending and receiving emails. Unlike third-party standalone email apps, like Gmail, Apple's built-in Mail app allows you to manage all your email accounts from a single place, including:

  • iCloud
  • Microsoft Exchange
  • Google
  • Yahoo!
  • AOL
  • Outlook

If you want to add your existing email account to Mail, open the Settings application and go to Mail > Accounts. Here you can add your account, which will then appear in the Mail app.

In the Mail app, go to the inbox of your chosen account (tap Mailbox to view all) and then create a new email. Draft your email as usual -- adding a recipient email address, subject, body and any attachments -- and then hit the blue button on the top-right to send your email. 

Once you do, you should be sent back to your inbox. At the bottom of the page, you'll see the words Undo Send in blue. By default, you only have 10 seconds to hit this button to unsend your recently sent email, or else it will irretrievably send and you won't be able to get it back. 

If you hit Undo Send, you'll be taken back to your email, where you can fix any mistakes or add any missing attachments, and then send it again. You'll have 10 seconds to undo the email if there is another error, just as before.

How to get more time to unsend an email on your iPhone

The way the unsend feature works is that instead of actually sending the email and then getting it back, it simply sets a buffer period between when you hit the send button and when the email is actually sent. The default time is 10 seconds, but you can go into your settings to increase this buffer.

In the Settings app, go to Mail > Undo Send Delay and then choose either delay time: 

  • Off
  • 10 seconds (default)
  • 20 seconds
  • 30 seconds

If you choose the Off option, you won't be able to use the unsend feature in the Mail app.
