There are many websites that offer disposable email addresses, and they're often very easy to use. Simply visit the website, enter the desired email address, and start using it. When you're done, simply delete the address. If you need a temporary email address, consider using a throwaway email service. It's a convenient and easy way to keep your primary email address private.
