You can start a newsletter for free, build an email list, and eventually turn your hobby into a business by charging for premium content. The platform handles the underlying infrastructure, including hosting, payment processing, and email delivery, so you can focus entirely on your creative output.
You can reach your audience directly in their inboxes while also maintaining a web-based archive of your posts.
