Now that iOS 16 allows you to unsend to email in Mail, you can save yourself from some unnecessary embarrassment by recalling a message that incomplete, ill-considered or riddled with typos.

But the window to recall a message is a narrow one — at most you have 30 seconds — so you better know exactly how to unsend an email in iOS 16 Mail before you install Apple's latest software update for the iPhone.

There's more to unsending an email on your iPhone than just tapping a button. You can also set how long of a delay you want before a message goes out, or you can turn off the unsend email feature altogether. It's simply a matter of going into the Settings app and making the right adjustments.

Here's everything you need to know about how to unsend and email in iOS 16 Mail, including the setting you need to adjust to change how long you've got to tap unsend.

How to adjust the Undo Send Delay for the Mail app

With iOS 16, the Undo Send feature is activated by default, though you only get 10 seconds to stop that message from going out. If that's too small of a delay, you can adjust the allotted time. Here's how to do it.

1. Go to Settings and select Mail.
