“We are saying goodbye to Inbox at the end of March 2019. While we were here, we found a new way to email with ideas like snooze, nudges, Smart Reply and more,” said Google in a notification to Inbox users.
Most of the popular features of Inbox are now part of the Gmail app. For instance, you can now “snooze emails” in the main app.
Google introduced Inbox by Gmail as a limited invitation-only email service in October 2014. The company mainly used it as a place to experiment with new email ideas like snoozing emails, Smart Reply, Nudges, and high-priority notifications. Four years later, Google has decided it doesn’t need the service anymore.
The primary feature of “Inbox by Gmail” was visible and rich “highlights” of each email message that users could see directly from their inbox without opening individual emails.
Back in September 2018, Google announced that it will shut down the service at the end of March 2019.
