How a Podcast Grows Your Newsletter (Without Extra Writing)

You’re growing your newsletter the hard way: Twitter threads, SEO, paid ads, cross-promotions. What if you could unlock a whole new audience — podcast listeners — without creating new content?

The Growth Math

Your newsletter reaches text readers. A podcast reaches audio listeners. These are partially overlapping but distinct audiences.

~500 million people listen to podcasts globally
~1 billion people read newsletters
The overlap is significant but not complete

Adding a podcast puts your content in front of people who would never subscribe to a text newsletter. They consume via Apple Podcasts, Spotify, and Overcast — platforms where your text newsletter is invisible.

Two Growth Mechanisms

1. New Subscribers (Acquisition)

Your podcast lives in podcast directories alongside millions of shows. Podcast listeners discover you through:

Search in Apple Podcasts/Spotify
Recommendations from other listeners
Sharing (audio clips, episode links)
RSS aggregators

Each podcast listener who discovers you is a potential newsletter subscriber — but they found you through a channel your text-only newsletter couldn’t reach.

2. Retained Subscribers (Churn Reduction)

Substack data: writers using audio grow 2.5x faster than text-only writers. Part of this is acquisition, but a significant part is retention. Subscribers who can listen when they can’t read don’t cancel.

At 6% monthly churn, reducing churn by 20% saves you 12% of your subscriber base over a year. That’s growth you don’t have to re-acquire.
