Back in May, Google announced new quick action buttons, letting users respond to emails without opening them. So, for example, if you want to let the sender know that you’re attending an event, you can do so directly from your inbox. No typing required.
Now it seems that Twitter has signed up, letting those who receive email notifications carry out actions with a single click. As you can see here, @mentions let you click ‘View Tweet’, which opens the message in the browser.
The same applies to other actions too. For example, 
a ‘Follow Back’ quick action in response to notifications for new followers.
Other users, including Abraham Williams and HTeuMeuLeu, have reported seeing this feature in their inbox too, so this covers the US, France and the UK at least, meaning it’s likely this is probably available globally, though it’s perhaps being tested with a select number of users in a handful of countries.
It’s not a huge development for sure, but it’s one designed to remove any semblance of friction from the Twitter user experience. You can read more about the these new Actions by following the link below.
