Google has added an Unsubscribe feature that will help you end email from unwanted email lists.

The Unsubscribe feature will be available for all KNOWN email lists that Google collects information about and if you are receiving mail and can’t find a way to stop it google will send a request on your behalf to have the service unsubscribe you.

Unfortunately spam will probably still get through but this is a quick and easy way to deal with services that you don’t want to be contacted from or ones that signed you up without your knowledge.
