Django app for email-based learning platforms

I built django-email-learning, an open-source Django app for running e-learning platforms where course content is delivered entirely via email rather than a web portal. Inspired by Darsnameh, an email-learning service that shut down in 2017. The core motivation is accessibility — email works in low-bandwidth environments, on any device, and is more resilient to censorship than web platforms. It's in beta (v0.2.54). To test the concept in production I built InboxAcademy.io on top of it, which currently hosts a course on using the package itself. Would love feedback on the architecture or general approach.
