title: Responsive images in an email
body: <p>I've been reading about <a href="https://css-tricks.com/responsive-images-youre-just-changing-resolutions-use-srcset/" rel="nofollow">srcset</a>, seems like a good way to handle responsive images.</p>
  
  <p>I was just wondering, would this work for images in emails? Or is there a better way to have responsive imagery in emails?</p>
