We're all about your subscribers.
Seriously. ConvertKit is a subscriber-centric platform, unlike many other platforms that tend to be list-centric. This means that you have more control over your list, better subscriber organization, and the best part- you can and will maintain better engagement with your list because they'll feel like you know them. Because you do!
As a subscriber-centric platform, you will be working from one list of subscribers, and then organizing them using tags and segments.
