OK, so Everlane is a (mostly, originally) online-only clothing retailer that started Facebook messaging me about my order status, including shipping updates. Obviously, this is when you&#x27;ve auth&#x27;d with them via Facebook. Messages can include html, including images and map data, so they used that to show tracking progress with some nice branding. I always wondered how they did that.<p>Nice use of the platform. If your user auths with Facebook, of course it makes sense to do your customer communication via Facebook, too.
