According to January 2018 statistics, Gmail boasts 1.2 billion users.
Google began alerting G Suite admins today that a “new Gmail experience” would be previewed in the coming weeks.
The improved design includes features such as offline support, smart replies and a snooze option to deal with annoying messages.
The Verge, however, has obtained a series screenshots that show three new layouts.
The new design features a sidebar with the option of using the Calendar, Keep note-taking app and tasks next to user's emails.
This could make it easier to schedule meetings and check availability while emailing people.
A default view highlights attachments such as documents and photos, a comfortable view doesn't show attachments, and a compact view shows more messages.
The 'snooze' button will also temporarily hide emails from user's inbox until a certain time.
Both Snooze and Smart Reply are part of Google's Inbox app on Gmail.
Google is also reportedly moving the existing stand-alone app, Gmail Offline, to a web-based variant.
The update will be first be available as an early access program for G Suite customers and people with personal accounts.
Sources say that popular Chrome extensions should continue to work in the new Gmail.
Recently the company release a new design for Google Calendar with modern icons and colours.
The design looked more like the mobile app meaning Gmail itself could be updated in a similar way.
Last but not least, Google's added three layout views that'll allow you to change how your mail is displayed. The default setup will showcase things like photos, documents, and other items that are attached to message, a comfortable option will remove these attachment highlights, and compact mode will show more emails on your screen at once.
It'll still be some time before these changes make their way to all Gmail users, but seeing as how Google I/O is right around the corner, we could get more details on Gmail's updated look during the upcoming developer conference.
