That’s definitely good advice for an established content creator who has an audience but it doesn’t solve the problem of reach. If I start a newsletter today I have no subscribers. How do I find them? If it’s an innocuous topic I’d probably start by sending my newsletter to friends and family and by posting links on social media. For the typical OF creator that isn’t really an option. Most links to pornographic content hosted on an unknown site are assumed to be spam or a scam.
