The fastest way to archive or delete emails from the Mail app on your iPhone, iPod touch, or iPad is to use the swipe gesture (though there is another way to delete emails). Here's how to set up swipe to delete and swipe to archive with the Mail app on iPhone, iPad, and iPod touch devices running iOS 10 or later.

Swipe actions may be set up on your device, but if swiping an email doesn't produce the desired results, follow these steps to change what happens when you drag an email left or right.

Open the Settings app.

Go to Mail and tap Swipe Options.
