Email has been around for a long time. It predates the Internet. Google is tweaking how email is displayed to users by adding features which makes it easier to get to the important data. Several months ago, Google added tabs to differentiate social updates and promotions from regular email. With Inbox, Google is adding Bundles, a feature that will group together similar messages, like bank statements and receipts for example. Another feature is called Highlights, which places important emails to the front and center. Inbox also has Reminders, Assists and Snooze. Reminders are pretty much self explanatory. Assists work with reminders to bring out relevant information. Snooze dismisses information in the background. Google Inbox is not available yet to all. You can ask for an invite by sending an email to firstname.lastname@example.org.
