If you need to give someone your email address, or need to sign up to a website which requires an email address, but you don't wish to reveal your identity then our free service for receiving emails is perfect. Simply signup instantly, give them the our disposable email address and you'll be able to read every email they send in complete privacy. Our free anonymous email service is also good to stop SPAM; if you don't trust a website asking for your email address, then give them one of ours instead."
