Gmail Labs have been busy creating some really cool features for Gmail, with a lot of them meant to spare you embarrassment down the line. These "embarrassment-reducers" include:

Undo Send which lets you retract a message up to 10 seconds after you’ve sent it. Perfect for those moments when you realise that you maybe shouldn’t say that to your boss, or that maybe you haven’t given him your whole mind and want to write some more.

Mail Goggles kicks in when you’ve had a few too many and want to start emailing your ex. So if you want to send an email between 10 pm and 4 am on a weekend, Gmail will send you some maths problems to solve before you can blast off those Jägermeister soaked love letters.

The latest of these features is what Google Labs is calling “Got the wrong Bob?” This is for those mails you wanted to send to Bob Geldof, but accidentally mailed to Bob Mugabe instead. After activating it from the Labs tab under Gmail Settings, Gmail will ask you if you meant to mail another person with the same name as the person listed in your email. The suggestions are based on persons you email the most often.
