We know how important it is to maintain control of your RSS feed and your subscribers. If you create your podcast with RSS.com and activate a redirect from your old SoundCloud RSS feed to your new rss.com feed you will not lose any subscribers.
Important: If you have multiple podcasts on your SoundCloud account you will need to redirect each feed individually.
Log in to your SoundCloud account
Go to your Content Settings page and enter the URL of your new RSS.com feed in the “Subscriber redirect” field. Since you can hold on to your free SoundCloud account forever, we’ll keep that 301 redirect in place indefinitely for zero cost.
