Newsletter Email Delivery

As a writer, I want my published entries to be optionally emailed to my followers who opt in to email delivery so I can reach my audience the way Substack and Ghost do, without requiring them to check the platform. Writers could toggle email delivery per entry at publish time. Followers could opt in to email updates from specific writers they follow. Plus subscribers would have full email delivery to all opted-in followers; free tier might be capped (e.g. up to 100 subscribers). Entry emails would render the full content with a header, the writer's name, and a link back to the platform.
