Use a disposable e-mail address
A person can't spend much time on the Web without encountering a site that can't be used unless you register by providing an e-mail address. Supplying your everyday e-mail address to each Web service that solicits one is just asking for spam.

If there's little chance you'll need to receive a correspondence from the service (once you've confirmed your registration, of course) enter an e-mail address you created with no intention of checking it for incoming messages. Alternatively, you could forward messages received at the throwaway address to a folder of your regular inbox and monitor the folder for received messages as needed.
