Today Google opened up its experimental email app, Inbox, to everyone — no invite required. Google announced the news on its blog during its I/O developer conference. Unfortunately, Inbox is still invite-only for Google Apps users.

Google also released a number of new features for Inbox: Trip Bundles collects emails about a trip in one place; Undo Send (which already exists in Gmail); and Swipe to Delete.

Here’s more detail, from Google’s post:

More ways to stay organized with Trip Bundles
For starters, you’ve mentioned how much you like seeing key information at a glance, like when your package is arriving. So today Inbox is adding Trip Bundles: All of your emails about a trip will now be bundled together and the most important details (like flight times and hotel reservation numbers) will be available the instant you open Inbox.

More control with Undo Send, Swipe to Delete and Signatures
Being able to control your inbox, like setting your custom Snooze times, is also something you’ve told us matters. So today Inbox is helping you be more productive:

  • With Undo Send — now for the first time on your phone — you can take back an email right after sending in case you spotted a mistake, or have second thoughts
  • If you’d rather get rid of messages, you can make Delete the default swiping action
  • If you want to personalize your sent messages, you can now add a custom signature

More ways that Inbox saves you time
You’ve also let us know how much you appreciate a little extra help every now and then — like when Inbox adds phone numbers to Reminders, or finds that flight time in under a second. Today Inbox is adding a few more ways it can be of service:

  • When you create Reminders in Keep, they’ll now appear in Inbox
  • When someone emails you a to-do, Inbox might suggest adding a Reminder so you don’t forget
  • When you get an email from HotelTonight or Eat24, you can now open your reservations and food orders within their app, directly from Inbox
