We need your email address so we can verify your identity and create you a secure account. You will add a password later. Your email is also required for you to communicate with your collaborators and for us to provide an effective customer service experience. You can easily opt in and out of how you receive marketing communications at any time using the MY DATA dashboard inside your account. If you want to change your email address in the future, contact our Customer Success Team using support@goproof.net.
