These Addons are all FREE! We are working on making a set of Instructions for the Addons. They are 100% FREE! We are working on adding a CRM and an Automatic Email Series Functionality which are going to be a part of the $5 Monthly Subscription because you will be required to connect the Email Functionality to an outside SMTP (we recommend SendGrid.com) which will cost around $10-$15 Monthly, but it is a normal thing to need in the world of online integration. After a while we are planning on making the same Email Functionality a part of what will become our $35 Monthly Subscription but with the additional option of using our PowerMTA Server so that you do not need an SMTP Server Subscription. We will keep you posted as we make progress.
