With the annual Google I/O conference firmly underway, the announcements are flowing like water. One of those is that Inbox by Gmail is now open to everyone.

The product was unveiled last fall as “the inbox that works for you”. It has been available on an invitation-only basis ever since. I had the good fortune of getting one fairly early, and I can’t say I was particularly fond of it. It didn’t take me long to switch back to Gmail. That said, a lot of people do seem to like it.

Now, a lot more people are going to have a chance to see what they think. It’s also getting some new features.

One new addition is that of Trip Bundles, which display all your emails about a trip in one bundle and the most important details, such as flight times and hotel reservation numbers will be available as soon as you open Inbox.

Also new are an Undo Send feature, which as Google points out, is the first time this has been available on your phone, as well as a swipe to delete function and custom signatures.

Another new feature shows the reminders you set in Keep in Inbox. Also, when someone emails you a to-do, Inbox may sugges adding a reminder so you don’t forget. And when you get an email from HotelTonight or Eat24, you can open your reservations and food orders with in their app from Inbox.

In addition to making Inbox available for all users, Google is expanding the early adopter program to all Google Apps for Work customers.
