> Pay to subscribe, and only you will get the newsletter. RSS feed can't limit only to subscribers. Patreon has this feature with their podcast RSS feeds.[1] When you subscribe, you get a URL with a personal, unique parameter. This feed has all the episodes that you pay for. Your version of the feed stops updating after you cancel your subscription. [1] They probably also have it for normal RSS feeds, but I've only used their podcast RSS feeds
