Google is bringing a major upgrade to Gmail that will let you interact with emails in your inbox just like you would with the web pages they often lead you to: look up hotel listings, fill out forms, and browse products you want to buy.

That’s thanks to Google’s AMP technology, which also powers many of the fast-loading mobile pages and articles on sites that use the framework. It’s rolling out to Gmail‘s desktop app today, and will eventually become available on mobile as well.
