Useful Gmail Features

Consolidating outside email account inboxes into one Gmail account is now easier. Use the import options under settings to add other accounts, and you'll be able to check all of your email in one place.

Undo Send. If you send an email to a wrong address, or write something you want to take back, Gmail give you 5 seconds to undo. You've got to be quick, but the option is there!

Never forget an attachment again. Use the Forgotten Attachment Detector to make sure you get the email recipient everything he or she needs the first time.
