Quote:Bundles: stay organized automatically
Inbox expands upon the categories wee introduced in Gmail last year, making it easy to deal with similar types of mail all at once. For example, all your purchase receipts or bank statements are neatly grouped together so that you can quickly review and then swipe them out of the way. You can even teach Inbox to adapt to the way you work by choosing which emails you’d like to see grouped together.

Highlights: the important info at a glance
Inbox highlights the key information from important messages, such as flight itineraries, event information, and photos and documents emailed to you by friends and family. Inbox will even display useful information from the web that wasn’t in the original email, such as the real-time status of your flights and package deliveries. Highlights and Bundles work together to give you just the information you need at a glance.

Reminders, Assists, and Snooze: your to-do’s on your own terms
Inbox makes it easy to focus on your priorities by letting you add your own Reminders, from picking up the dry cleaning to giving your parents a call. No matter what you need to remember, your inbox becomes a centralized place to keep track of the things you need to get back to.
