Google to offer Inbox to its business customers starting next month
With Inbox at the office, you can more easily keep track of your appointments. Certain email messages related to corporation business can be snoozed until they are officially released, lowering the odds of someone stealing the information from your phone and getting it in advance. And Google says that since Inbox was built on the same infrastructure as Gmail, it is secure enough for corporate use.
In March, Google plans on offering Inbox to some of its Google Apps customers for case studies. If you think that you'd like to use Inbox as your primary email client for work, and your firm has many mobile users, you should send an emailed request for a Inbox invite from your Google Apps for Work administrator account. You need to send the request to firstname.lastname@example.org. Those who are approved will get to help Google build Inbox for work.
