Launched the method as an email drip to beta testers. Some emails were too long. After this test I decided to move everything to a website. The advantage of the website is that it is easier to read longer texts and to do some of the work, even if it is in the same browser that you would use to read email. There's some sort of a psychological barrier to long emails, specially if you are learning from them. What I think may be an issue with the website is engagement.
