Managing paid content in your post
Global Setting
You have two options to manage paid content. The first is the global setting. Once you are ready to publish your post, if you click on the visibility option, you have the option here to segment your audience. You can send the post to only paid subscribers, or to both paid and unpaid subscribers.

Posts that are sent only to paid subscribers will show up as blurred in your visual archive for non-subscribers. If you sent a post to both paid and unpaid subscribers you will need to manage paid content at the content-level.
Content-Level Setting
Paid content can also be turned on at the content level by going to the image menu and toggling paid content on. Once this is done you will see a paid content icon appear in the corner. This content will appear blurred to non subscribers.

Paywall Divider
If you wish to paywall an entire section of your post, i.e, you start the post with some free content that everyone can see, then you want the rest of it to only be viewable to paid subscribers, simply use the 'Add Paywall Divider' from the Add Others menu:

Once added, all content below the divider will only appear to paid subscribers. You can reorder the paywall divider like any other piece of content using the re-order feature.

Previewing
You can preview your post to see what it will look like to free subscribers by hitting the preview button at the top of the composer:
