Make the Most Out Of Haptic Touch (or 3D Touch)
Whether you’re one of the rare who still uses 3D Touch, or you’re already rocking Haptic Touch, you can use it to find a bunch of extra features and quick actions in the Mail app.
For instance, if you long-press the Mail app from your iPhone’s Home Screen, you’ll quickly be able to do things like create new messages, search for an email, or access your VIP folder in a matter of seconds.
But one of the coolest features is inside the Mail app is that if you long-press an email, you’ll get a preview of the whole email without having to open it. Not only that, but you’ll also have some quick actions you can perform, like replying or forwarding the email to someone else.
Want to know something even cooler? If you enter an email and someone sends you a link, you can long-press it to see a web page preview before actually opening the link. The same goes for any file. Just long-press it, and you’ll see a preview of any document you receive.
