Choose, post by post, whether your content is free for everyone or reserved for paying subscribers.
This requires paid subscriptions to be enabled on your blog. Set up paid subscriptions first.
When writing or editing a post, you'll find an Access option in the right sidebar:
You can change this setting at any time, even after publishing.
When a non-subscriber visits a paid post, they see a teaser (the beginning of the article) followed by a paywall with a subscribe button. The rest of the content is hidden until they subscribe.
Subscribers see the full post with no interruption.
In Settings → Membership, you can set the default access mode for all new posts — Free or Paid. This is just a default: you can always override it per post.
If you're just starting with paid subscriptions, keeping the default on Free and manually marking your best content as Paid is a common approach.
If you turn off paid subscriptions in settings, all content becomes accessible to everyone regardless of the access mode set on individual posts. The access settings are preserved — re-enabling paid subscriptions will restore the original behavior.
