According to, Google’s email service Gmail is used by more than 1,5 billion active users worldwide. There have been many Gmail innovations since its introduction in 2004 in order to improve user-experience. Many such improvements have inspired other email services such as, Yahoo and to adopt those email innovations into their services as well. Gmail’s implementation of is as of today the most comprehensive. Here is an overview of how is already used to enhance the email user experience in Gmail:

  • Gmail Actions: Accelerate user actions, such as one-click and go-to actions (two examples below).
  • Highlights in Inbox: The most important information users need from an email are highlighted such as events and flights. Also RSVP, one-click and go-to actions are highlighted.
  • Gmail Promotions Tab: Automatical grouping and highlighting of email promotions.
  • Answers in Search: Using schema markup to allow your recipients to find information faster.
  • Confirmation Cards: Elevate directions, flight status updates, check-out time in hotels, and more.
  • Google Calendar: Using schema markup to extract event information from booking confirmation emails, adding them to Calendar automatically.

In the following two examples we will take a look at at a one-click actions, these are scenarios where an expected behavior from a user is to confirm a pre-defined request. For instance, an event website sends out an email asking to confirm the registration and a music store sites send an email offering to add items to a queue for later pre-listening. In this case, the email recipient doesn’t have to leave his Gmail inbox and just has to click the single button ‘Add to Queue‘ in order to perform the one-click action: enriched email with one-click actions in Gmail and Inbox (Source: Google)

In the next example, an event with RSVP Gmail Actions support is shown both in Gmail as well as Inbox (Gmail’s mobile app):

Using in Gmail for RSVP Actions as shown above can be used to respond directly within the email inbox realm (without leaving the email web or client interface). In this example the user can respond directly to an event invitation inside the inbox. It renders the action by showing all the details of the event including ‘Yes‘, ‘No‘, and ‘Maybe‘ responses which can be defined by the sender. support in Microsoft Outlook

Microsoft supports within Outlook and calls its support for the semantic markup ‘Actionable Messages‘. Those actionable messages enable you to take quick actions right from within Outlook. It is already fully supported in all recent desktop Outlook versions and Outlook Web Access and according to Microsoft, the new feature is coming to Outlook for Mac and Outlook Mobile soon as well.

In the example shown above, an employee submits an expense report to an internal system which sends back an Actionable Message to the person who is to approve or reject the expense. The automatically rendered card within the message contains all information necessary for the approver to quickly understand who submitted the expense, the total amount, and more. It also includes ‘Approve‘ and ‘Reject‘ action links that can be taken right from within Outlook. The user does not have to leave his email client in order to perform these actions.

How to test your markup

With Google Apps Script, Google for example provides a free service for interacting with user data, other internal as well as external systems. You can use Apps Script to test your markup by sending yourself an email including schemas.

Microsoft provides an Email Development Dashboard to test their enriched ‘actionable messages’ for the Outlook product range. Using Microsoft’s Card Playground, you are able to test sending actionable messages to your own inbox.

Considerations and limitations

This way, Google makes sure to see that you are trustworthy, requiring you to not have any or only a very low rate of spam complaints from Gmail recipients.

A quite similar process is necessary if you want to see the Microsoft Outlook way of implemention in action. You must go through through Microsoft’s registration and verification process before you can use the actionable messages in Outlook: Microsoft’s email sender guidelines. is primarily used in Gmail and Outlook, summing up to a substantial email client market share in the business world.
