Blogging or running a site is useless if you are not converting your visitors into returning visitors or customers. A blog’s reader or an ecommerce's site customers can be engaged more using a user friendly subscription form that may blend perfectly to your site layout. Generating new leads is not an easy task. If you are in legal business, you would do this via a subscription form. Building a clean email list is all you need to run a productive email marketing strategy for consistent flow of income from recurring customers.
