Ending the year, Google announced that it has sent out the last batch of Inbox invitations for 2014. Those who requested an invitation by emailing Google directly were given one, and Google says that it won't be sending out new invitations for the Gmail-based email service until 2015.
More invites just went out to those that emailed firstname.lastname@example.org. The last of the year – we're hitting the snooze button till 2015.— Inbox by Gmail (@inboxbygmail) December 19, 2014
