You don’t have to use Dovetail Inventory to use Dovetail Podcasts. You are more than welcome to include your ads directly in your audio files (known as baked-in ads). If you are interested in using Dovetail Podcasts without Dovetail Inventory, please reach out to podcast-support@prx.org.
However, if you think you might be interested in using Dovetail Inventory in the future be sure to keep an ad-free version of your audio files for a seamless transition.
