Jetpack provides you a built-in email subscription module that allows your visitors to subscribe for latest posts updates on your WordPress site. By default, Jetpack provides you a subscription widget you can add to your sidebar and rest all works automatically.
Your visitors subscribe to your website and get email alerts for new posts. In this lesson you will see how to add a more beautiful and eye catching Jetpack follow box on your WordPress site.
Better Follow Button for Jetpack is the new Jetpack addon plugin for WordPress users. It allows you to add a floating cutomizable follow button (as on WordPress.COM Blogs) to Jetpack-powered self-hosted WordPress blogs.
The box is integrated with the built in subscription module of Jetpack to collect the email of the subscriber and handle distribution of new posts via email.
