How do I unsubscribe from a podcast?
In the Podcasts app for iOS, you can manage your podcast subscriptions in My Podcasts. Select a subscribed podcast, tap Settings, and turn off the Subscription setting.
On your Mac or PC, you can manage your podcast subscriptions in the Podcasts section of your iTunes library. Select a subscribed podcast, click the Settings gear icon, and deselect the Subscribed tickbox.
