I picked up codes for Mastera somewhat reluctantly. I currently use Groovefunnels for web building as well as for some courses I've created. That being said, what it lacks is a way to communicate with members of the course, which is why I picked up Mastera - the unified inbox. If you are someone looking to create and launch a course, and don't have an LMS or other service, the Mastera is a great tool to help get your course out and launched, connected with your students, and remove all of the unnecessary stuff you might encounter in other tools (like Groovefunnels). Mastera is pretty easy and straightforward to use to create your course, billing, etc (which only a couple of years back was a nightmare on WP). If you have another tool with membership already built in, then Mastera might not do much for you. If, however, you want a single place to house your courses, student management, billing, and communication, then definitely check out Mastera because it stays in its lane and does what it does well.
