Gmail which introduces new features almost every day has introduced one more facility today. This is "Message sneak peak". This is a gmail Lab feature. You can go to settings -- Lab and enable this one and save. Once enabled, you can right click on any message without actually opening it, have a view of the message and if necessary keep it or delete it without opening the message.
