Yahoo Mail just made its link previews on desktop richer and more informative. When you paste a URL into the body of your email, you'll now get a preview card that contains not only a snapshot of the website, but also the author's name, if applicable. In case the link points to a hotel website, you'll see prices in the card. Even better, if it's a link to a video or an audio clip on YouTube, SoundCloud, Tumblr or Vimeo (among other services), you can play it within the email itself. Not to mention, you can post the links to Tumblr, Facebook and Twitter through the new Share button at the top right corner of the image.
