LearnDash – ConvertKit
Display subscription form or automatically subscribe students
When enabled for a course, a prompt to subscribe to your newsletter will display during course registration for new students. If they’re logged in, all they need to do is click the button! You can also simply enable automatic subscriptions so that students are added to the proper ConvertKit form and Tags, without the student ever needing to click anything!
