With the debut of 3D Touch on the iPhone 6s and iPhone 6s Plus, Apple offers a number of new ways to preview and manage content on their flagship devices. 3D Touch is particularly handy to use in the Mail app.
To quickly preview an email on your iPhone 6s/6s Plus, simply press firmly on the email you wish to preview from your inbox. You’ll see a preview of the email appear on screen, as long as you keep the pressure up. To “pop” into the full email view, simply press a bit harder, and the full view will appear, or lift your finger to return to your inbox.
Press firmly on the email you wish to manage, just as you did in the preview step above. While still holding down with your finger, swipe left to delete or archive the email, or swipe right to mark it unread.
You can also swipe up with your finger to view a number of other options, such as: “Reply,” “Forward,” “Mark…”, “Notify Me…”, and “Move Message… ”
As before, you can press harder to “pop” into the full view of the email, or lift your finger to return to your inbox.
