About Private Substacks

Our new-and-improved private publications work much like a private Instagram profile. Curious readers can now request to subscribe to a private Substack, and the writer can choose to approve or decline each subscription request.

Private Substacks are great for:
  • Keeping in touch with friends. On Substack, you get a direct line of communication to all of your subscribers via email and our apps. Algorithms don’t decide if your friends will see your posts.
  • Building communities of interest. Host conversations about niche topics with posts, Threads, and Chat.
  • Testing the waters. See if there’s an audience for your writing before publicly launching a Substack.

To start your own private publication and claim a Substack URL, simply start a Substack and select "Private" in your settings.
