Photo: Gmail develops a new feature

Google's Gmail email service is preparing to launch a new feature on its platform. This new feature will help users see active mailing addresses.

This new feature will allow users to see if the Gmail email address to which they are sending the message is available at that time or not, since a notice appears at the bottom of the message writing window .

To do this, Gmail relies on sync information from the Google Calendar service to find out when the recipient is.
