Google's team behind the development of Gmail has just introduced Inbox, an email service that allows users to organize emails and reminders and shows information such as flight bookings and events. Inbox expands upon the categories Google 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 grouped together. You can even teach Inbox to adapt to the way you work by choosing which emails you’d like to see grouped together.

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 information from the web that wasn’t in the original email, such as the real-time status of your flights and package deliveries.

Inbox also lets you add your own Reminders, from picking up the dry cleaning to giving your parents a call.

Last but not least, Inbox provides Assists - pieces of information you may need to get the job done. For example, if you write a Reminder to call the hardware store, Inbox will supply the store’s phone number and tell you if it's open. Assists work for your email, too. If you make a restaurant reservation online, Inbox adds a map to your confirmation email.

Starting today, Google is sending out the first round of invitations to give Inbox a try, and each new user will be able to invite their friends. You can email Google at inbox@google.com to get an invitation as soon as more become available.
