CodeCanyon - Simple Subscription Popup-jQuery Email Signup Form v1.43
With Simple Signup Form jQuery Plugin, you can collect your visitor's email address on your website. It has a lot of optional customization options, but you can setup simply in minutes. Using the latest CSS3 animations with AJAX validation the Signup Form will build your email list effectively in no time. You can use it with MailChimp, but if you have any other email database manager, you can use it with that as well. In that case, the plugin will send you a message about every subscription with the user's email address, therefore you can easily add it to your own email list manager. You can also use this function as a signup notification.
