I just recently moved my email newsletter from MailChimp to [ConvertKit]( http://mbsy.co/cPPQ2).

What’s awesome about ConvertKit is that it’s “subscriber” centric. Whereas MailChimp is “list” centric.

The reason a subscriber-centric email service is so great is because it means you can be far more intentional and relevant when it comes to your ability to providing value to your newsletter subscribers. ConvertKit lets you track where people sign up, and you can tag them based on the products they buy from you, the free downloads you give away, and other things. And these tags allow you do a lot of really clever content strategy, cross-promotion, etc.

So you could have a unique tag for your newsletter subscribers, each of your courses, and your products. Then you can uniquely target those different people.
