However, to keep its loyal customers, Google ensured current users get a pop up notification when they open their Inbox. The message leads to the Gmail app, whose mobile version already includes some of Inbox's main features, such as Smart Reply, Smart Compose and Follow-ups.
Introudced five years ago, the Inbox app represented a combination of email components, such as bank invoices, highlights of related information (like Google Now alerting you to flight changes, traffic, among others) and updates on your appointments, including reminders.
With the major reshuffle and redesign of Gmail coming up, apps like Google Calendar, will be made more accessible from the Gmail web interface.
Users will also have access to Smart Reply on the web, not just mobile, and snooze emails, choosing when they show back up in their inbox.
