What's the difference between Public, Subscribers and Premium posts?

When you create a post, you choose who can see it under Post Type.

Public

Free for everyone. Subscribers and non-subscribers both see it. Public posts are a good way to show new fans what you post, and they can appear in the home feed and Explore.

Subscribers

Only your current paying subscribers see it. It's included in what they pay for their subscription. You need a subscription plan before you can post to subscribers.

Premium

Fans pay an extra price to unlock it, even if they already subscribe. When you choose Premium, you add a price and can add preview content that fans see before they unlock. Premium isn't available for stories.

The price for a Premium post has to fall between a minimum and a maximum, which the form shows you if you're outside it.
