The world’s most popular email service is getting a big overhaul today. Google is making official the changes The Verge leaked earlier this month, with email snoozing, nudging, and confidential mode making their debut alongside a substantial visual redesign for Gmail on the web. The new Gmail begins a global phased rollout today, which is to say that it won’t be available to every one of Gmail’s 1.4 billion users right away, and the first to get it will be invited to opt in rather than being able to just turn it on themselves.
