Plugin for Users Database

Does anyone know of a plugin that will not allow the information from the registration process to find its way into the database or users page in admin until the admin receives an email to approve or delete it? I don’t want to have to go into my users page inside admin and manually delete all the bogus registrations that keep popping up. It seems that a new users info is automatically inserted into the users section under admin before I get the chance to delete it in the email. Ideally I would like the option to delete the spammers from my email inbox without having to go to the users section at all until I see a legit user registration. Is this even possible? I have tried “new user approve” but that doesn’t do it.
