The good news is, you have until March 2019 before you have to switch to Gmail or another app. Hopefully, we see it before the March 2019 retirement date for Inbox. After four years of service, many - although not all - of Inbox's features have been incorporated into Gmail, and Google now feels it is time to concentrate on a single email tool.
Inbox, Google's innovative app for email, has received its death sentence. All your conversations are already waiting for you in Gmail. Like you can use Stars, custom labels, or use Gmail search if you used Pins in Inbox. Featuring tight integration with other Google services, Inbox quickly garnered a group of passionate followers.
As years rolled out, Inbox became more popular among its users, and later began rolling out forward-thinking feature like Smart Replies and Unified Inbox. The death of Inbox is not entirely out of the blue - numerous features that made it unique have become part of Gmail over the years.
Today (very predictably, we would argue) Gmail product manager Matthew Izatt announced via a blog post that Google is sunsetting the more experimental Inbox app and bringing over things the company has learned to the main Gmail app. This merging of features led to uncertainty about the future of Inbox, and ultimately, to its demise. At that time, any Gmail addresses that were tied to Inbox will revert to the standard Gmail experience, and the mobile app will stop working. What do you think of this move? And I have six months to mull this over. But. Gmail, by comparison, is very busy, even the new version. Maybe Inbox was doomed from the start, but erase the frustration of Inbox users on this sad day.
