Inbox by GMail is now open to all, gains new features and works with Google Keep

Google's Inbox by GMail, email client is a more polished and user-friendly alternative to GMail. Up until now, the only way to use the app was to score an invite to use the service. Today the app has been updated, you no longer need an invite to use Inbox. 

Frankly, most users who have been interested in trying out the email client have probably already got hold of an invite, but dropping the invite system is a welcome announcement, which will allow just anyone with a supported Android device to can now try Inbox out.

The update also brings a few new features and improvements to the app, the most notable ones being the addition of Trip Bundles, which gives you an insight on flight schedules, reservation information, and other types of data. Undo Send, on the other hand, is pretty self-explanatory - if you suddenly change your mind, you can "unsend" an email that you've just sent down the line. Of course, this feature will require you to act quickly, yet nonetheless it's a most welcome addition.

Additionally, you can now add customized signatures at the end of your emails, a small but nice touch that will stand high in some users' books, probably. Synchronization with other Google apps, such as Google Keep, is now also on board, allowing your reminders or notes to appear straight into Inbox.
