On Wednesday, Google revealed "Inbox," a Web- and app-based e-mail platform that strives to integrate your mailbox with your calendar and to-do list.

"Inbox is by the same people who brought you Gmail, but it’s not Gmail: it’s a completely different type of inbox, designed to focus on what really matters," Android SVP Sundar Pichai wrote at Google's official blog.

The Inbox interface screams "Material" redesign, and its sidebar comes with a much wider range of sub-categories, dubbed "bundles," to divide your mail between. There are so many, in fact, that the typical Hangout list in Gmail has been forced to the right side of the Web app. The mobile app—only shown today as an Android option, natch—appears to put a stress around such bundling by default, as opposed to presenting e-mails in a default time orientation.

Inbox will automatically pick through message content to find dates and times to build tasks, or if a user makes their own to-do note, Inbox will try to fill it in with "assists" like phone numbers or hours of operation. Want to put something off? Inbox also comes with a "snooze" feature that can remind you about a message or task either at a certain time (sometimes propagated by the e-mail itself) or when you return to a certain location.

Over the past year-plus, Google has hinted at such a mail-and-task symbiosis by rolling out a number of automatic task-fetching features over its app and Web service spectrum. In particular, a flight confirmation or notification sent to a Gmail account will, by default, modify any searches users make for their flight information.

This reveal lined up with rumors and screens going as far back as May of this year of an impending Gmail overhaul. That May leak also hinted at the Material design that Android users are about to get to know and love with the impending launch of Android's Lollipop update. Pichai's post indicated that the invite-only service has already begun rolling out to select users. In the meantime, users can yell or beg for their own invites by e-mailing inbox@google.com starting today. We'll update with impressions as soon as Google deigns us worthy enough to take the Inbox plunge.
