I'm about to launch a new course and I wanted to ask if the following link is allowed in the content.
However, I still have doubts about whether it's allowed or not.
I want to include a link to a landing page where I offer my book and guide related to the course, completely for free.
But on the landing page, I ask for an email, which would be personal information.
Is this allowed?
No, you cannot link a book on your landing page or ask for an email. Both are not allowed on the landing page of your course.
However, you can do both in the Bonus Section of your course. You can encourage your students to check out your bonus section but to be honest, I wouldn't mention what is in there explicitly in any email just to be safe.
Hope this helps.
