I use this thing whenever I need temporary registration somewhere. You get no unnecessary mails on the main mailbox, no spam, nothing. Would recommend!
Disposable mail is a wonderful tool for protecting privacy/security.
However, I dinged this one a notch because of the XSS to Gwallet. Naturally, I urge leaving that one blocked.
Safe site. Handy tool. Temporary email address for minutes. Time limit can be extended if needed. Useful for sites that ask for email address. Can read the email & even reply with it. Just click & copy to your clipboard.
