@djumper512 would you be fine with 100% email delivery? There's nothing wrong with that method, although some people would argue there's more perceived value with it being on a website as well. I think in your case though, it's very clear that having little or no hoops to jump through is important.
Do you already have an autoresponder with your email list provider? If not, by far the easiest autoresponder system I've used recently has been via mailerlite. It's not fancy though... there's not "if / else" scenarios. It's either driven by a specific date (a birthday / anniversary) or a number of days after the person signed up.
In the case of a 9 week course, this would make perfect sense....but not ideal if you have more complicated offerings in the future that you'd also like to delivery via email.
But, for the moment, it would be super easy to set up.
I'll make a short video for you, so I can show you what I mean
