Launching late last fall, Google’s refreshed email experience known as Inbox was available in a limited number of places. Previously, only iPhone, Android and Chrome browser users were able to access the new email client, but it appears Google is launching on new platforms starting today.

While the search giant is completely opening the flood gates, it is adding more devices and web apps to its list of supported platforms for Inbox. According to a post on the official Gmail Blog today, both Android tablet and iPad users will now have access to the app the same way smartphone and iPhone users did previously. Google has also added both Firefox and Apple’s Safari browser as supported web platforms on top of Chrome. 

Initial reports suggest functionality is very similar across all platforms, but Inbox is still a stripped down version of what we get inside of Gmail in many ways. Inbox still doesn’t support custom domains, a singular multiple accounts view and a number of other bells and whistles we have come to know from our Gmail accounts.

No matter which devices you own, you will still need to receive an invite to get access to Inbox. Google appears to be still testing the water with its new email client. Those interested can email inbox@google.com to request access and Google will send you one when “more invites are available.”
