Whether you encounter a link in an email, a text, or while browsing the web, as long as you have an iPhone 6s or 6s Plus, you can use 3D Touch to preview the web page in Safari without actually opening it.
When you come across a webpage you'd like to peek at, just firmly press the link to open a preview window.
Swipe up without lifting your finger if you want to bring up a menu of further actions such as opening the link in a new tab, copying it, or adding it to your Reading List.
If you want to return to what you were originally looking at, just lift your finger from your iPhone's screen.
Or you can press harder on the screen to fully open the new webpage.
