You don't need to publish your created episode immediately, but you can define a publishing time in the future.
To do this, first configure the episode completely under "New episode --> General". Then click on the button "Publish" and a window will open in which you can plan the live run of your episode in advance. Enter your desired date and an exact time:
Please note the following: On the selected release date, the episode will be delivered and made available in your RSS feed. However, it is possible that Spotify and others will show your latest episode a little later than at your selected time. The platforms must first access your feed and register that there is new content. As a hosting service, we have no influence on the regularity with which the podcast platforms retrieve your RSS feed.
