Instead of adding Substack newsletters one by one, you can connect your Substack account and import all your subscriptions at once.
Paid Substack subscribers: Use email forwarding insteadIf you’re subscribed to paid Substacks, this import feature will only capture the free preview, not the full content. We strongly recommend using email auto-forwarding and adding your newsletters to an Email block instead. This way, you’ll get the complete content of paid newsletters.
Best for quick imports: This feature is designed as a fast way to bring in all your free Substack subscriptions. For better management and full control, consider using email forwarding to add newsletters to an Email block instead.This import is available when adding an RSS block. You can also add individual Substack newsletters by pasting their URLs directly.
Try using the alternative URL format (@username vs profile/username)
Some newsletters missing
Only newsletters visible in your public Reads will be imported. Check your Reads privacy settings and make sure the newsletters you want are set to public.
Already have newsletters via email
If you’re already receiving Substack newsletters via email forwarding, you don’t need to import them as RSS sources. You can add them to an Email block instead.
