Almost everybody, or at least who I know has more than two Email accounts. Since Gmail or Google mail is the most widely used email service across the globe, people have multiple Gmail accounts too. I have seen many people who operate one Gmail ID for doing one kind of business. Even myself! I have one Gmail account on which I take subscriptions, one account I use for banking, jobs, and education stuff, and one for my social media accounts. Now, what if I want to access all of my Gmail accounts at once? Is it possible?
