You can make episodes available only to individuals who subscribe to your podcast through your PodOps podcast website.
You’ll find an option to do this when editing an episode (Podcast > Episodes).
Within the episode editor, above the Save button, you will find a checkbox. By selecting: Private (Private episodes appear only to your subscribers) your episode will not appear on your podcast website to anyone who has not subscribed.
If your RSS Feed is connected to podcast directories (Apple Podcasts, Spotify, etc.) your episode will be available there when Private is checked.
If you wish to hide your episode from your RSS Feed and connected Directories, check the box next to Hide From RSS Feed and Directories.
