I've been assembling the building blocks of a group coaching program that will equip you with the essential skills a copywriter needs to market a 'done-for-you' service you could market/sell to newsletter publishers on Substack, Ghost, or Beehiiv newsletter platforms (Ghost and Beehiiv are Substack competitors).
(BTW, this post is an example of a 'hand-raiser' exercise whereby I ask you to 'raise your hand' if an idea interests you. I'm measuring interest right now, so if you are interested in learning copywriting, please like this post or respond with "I'm interested.")
