How do I redirect my Substack podcast feed?

After importing your podcast into Transistor, set up a 301 redirect on your old Substack feed so it points to your new Transistor feed. Your existing subscribers and podcast app listings then follow you automatically, so you don't lose anyone.


If you haven't imported your show yet, follow How do I import my podcast to Transistor? first.


Export your Analytics


It's a good idea to export your analytics from Substack at this point. Analytics don't move between hosts, so it's good to keep a copy for your own records.


How to redirect your feed from Substack to Transistor


In Transistor, open your podcast, go to the Distribution tab and copy your new RSS feed from Your RSS Feed. You'll need it for the redirect.


  1. Log in to Substack
  2. Click the Podcast tab
  3. Click Settings
  4. Scroll to the bottom and find the Migrate podcast section
  5. Click Redirect RSS feed
  6. Paste in your Transistor RSS feed and save the changes


What if I no longer have a Substack account?


If you no longer have a Substack account, you can still email Substack's support team at support@substack.com and ask them to set up a 301 redirect for you.


You can use this email template:


"I have moved my podcast to Transistor.fm. Please redirect my podcast called (insert podcast name) using (insert old Substack RSS feed) to my new host Transistor (insert new Transistor RSS feed). Please let me know once the redirect is active."


You can also reach Substack through their contact page or search the Substack help center.


What does a 301 redirect do?


A 301 redirect for your podcast RSS feed is very useful when you move to a new podcast host. It ensures that any subscriber or podcast platform still using your Substack feed won't be faced with a broken link. Enabling a redirect means that your existing subscribers will stay subscribed and podcast directories can continue to pick up your new episodes.


A redirect is like leaving a forwarding address. It lets anyone using your old feed know where you have moved to.


How long does a 301 redirect last?


Almost all hosts keep the redirect in place permanently after you leave. With few exceptions, this is the industry standard.


How long does it take to enable a 301 redirect?


A redirect should be active within a couple of minutes of it being applied to your Substack feed. Podcast directories will then be able to pick up your new episodes from Transistor the next time they check your feed. That's usually within 24 hours of your redirect being active.


How to test if a 301 redirect is working?


If you visit your Substack feed link in a browser, it should automatically redirect to your Transistor RSS feed.


What happens if I don't forward my old feed from Substack?


If you choose not to redirect your podcast, you may need to complete a few extra steps.


Without a redirect, existing subscribers won't know where you have moved to. They will need to manually re-subscribe to your new Transistor podcast feed, so be prepared to share your new feed to win back your subscribers.


Without a redirect, podcast directories like Apple and Spotify will still be using your old Substack feed. To fix that, you'll need to go to those platforms and update the feed they use for your podcast. See:



Don't submit your podcast to the same apps again


If your podcast is already listed on Apple Podcasts, Spotify or other apps, don't submit it again from the Distribution tab in Transistor. Submitting again creates a duplicate listing, and your redirect already keeps your existing listings up to date. If you're not sure, get in touch with our support team.
