I was just wondering if there are any infringements there since it's other peoples work? Although I appreciate that it's not too dissimilar to selling your Star Wars collection and it saves people the time to collect everything themselves.
How would it work if I (for example) built a swipe file on email marketing and just signed up to your list and kept every email and sold it as a resource on how to write emails and get them opened.
Just an example ... I promise!! Your list is safe!
