You’ve seen the data: Substack writers using audio grow 2.5x faster. Beehiiv just launched podcast hosting. Your competitors are adding audio. Should you?
The short answer: probably yes, but the how matters more than the whether.
Retention: 4-8% of paid subscribers churn monthly. The most common reason: they fall behind on reading. Audio gives them another way to consume your work.
Reach: Some people prefer audio. They’re podcast listeners, not newsletter readers. Without audio, you’re invisible to them.
Engagement: Subscribers who consume your content through multiple formats (text + audio) are stickier than single-format subscribers.
Distribution: A podcast RSS feed puts your content in Apple Podcasts and Spotify — platforms with hundreds of millions of users who will never see your newsletter.
Time cost: Recording yourself takes 30-60 minutes per edition. That’s time not spent writing.
Quality expectations: A bad podcast is worse than no podcast. Listeners compare you to professionally produced shows.
Audience mismatch: If your newsletter is visual-heavy (charts, infographics, code), audio may not translate well.
Tools like audiclip auto-generate podcast episodes from your newsletter. Two AI hosts discuss each edition conversationally. Zero recording. Zero editing. Zero extra work.
Cost: Free during early access (audiclip) / 48/episode (Aloudable) Quality: Good and improving. Not as personal as your own voice but better than TTS. Best for: Authors who want audio without any time investment.
Substack offers AI voiceover (limited rollout). Beehiiv has podcast hosting. These read your text in a single synthetic voice.
Cost: Free Quality: Robotic. Verbatim reading. No conversation or summarization. Best for: Testing whether subscribers want audio at all.
Read your newsletter aloud or riff on the topic. Your voice. Your personality. The most authentic option.
Cost: Your time (30-60 min per edition) + basic audio equipment Quality: As good as your delivery skills Best for: Authors whose personality IS the product (comedians, storytellers, opinion columnists)
Hire a podcast editor or use a service to produce polished episodes. Professional intros, music, editing.
Cost: $200-500 per episode Quality: Professional Best for: Authors earning enough to justify the cost
| Your situation | Best option |
|---|---|
| ”I have zero extra time” | AI generation (audiclip) |
| “I want to test demand first” | Platform TTS (free) |
| “My voice IS the brand” | Record yourself |
| ”I earn $10K+/mo from the newsletter” | Hire production |
Don’t let “I don’t have time to record” stop you from offering audio. AI generation removes the time barrier entirely. Start there. If subscribers respond, you can upgrade to recording yourself later.
Start with zero effort. Upgrade when it matters.
