There is no way to manually submit to Castro. This is because Castro reads off of the Apple Podcasts directories, so as long as your podcast is in Apple Podcasts, it will appear on Castro too!

How to Find Your Castro Link

  1. Find your Apple Podcasts ID. It is the number at the end of your Apple Podcasts link.
    So your ID would be 1449965359.

This is your Castro link 👍
