Three problems, not one#
Turning a newsletter into a podcast means solving three separate things, and most guides only address the first.
- Making the audio. Something has to turn your written issue into a listenable file.
- Hosting it and generating an RSS feed. A podcast is technically just an RSS feed with audio files attached. Without one, you have an MP3, not a podcast.
- Distributing it. Submitting that feed to Apple Podcasts, Spotify, and wherever else your readers listen.
Whether this is a ten-minute job or a weekend project comes down to how many of those three your newsletter platform already handles. Some handle all three. Most handle none.
Start by finding yourself below.
What your platform already does#
Substack handles all three. Podcast hosting, auto-generated RSS distribution to Apple Podcasts and Spotify, private subscriber-only feeds, and a built-in AI voiceover that narrates written posts using six voices. If you are on Substack, most of this article is unnecessary and you should read our dedicated guide on Substack to podcast instead.
beehiiv added podcast hosting as part of its late-2025 release, alongside AI website building and digital product sales. If you are on beehiiv, check your current dashboard, since this is recent enough that the specifics keep moving. Platform feature sets change quickly, so verify against current documentation rather than any article, including this one.
Ghost, Kit (formerly ConvertKit), Mailchimp, MailerLite, Buttondown, and most general email platforms do not include podcast hosting. You can usually embed an audio player in an email or a post, but embedding is not the same as having a podcast. An embedded player reaches people reading the email. A podcast feed reaches people in Apple Podcasts and Spotify, which is the entire point of doing this.
If you are in that third group, you need external hosting. That is the main practical difference, and it is not a large obstacle.
The external hosting route#
For everyone whose platform does not do this natively, the setup is straightforward and mostly one-time.
Pick a podcast host. Several have free tiers with storage limits generous enough for a first season. The host does one essential job: it stores your audio files and generates a valid RSS feed. Everything else it offers is secondary.
Submit the feed once. You give that RSS URL to Apple Podcasts and Spotify a single time. After that, every new episode you upload propagates automatically. This is the step people assume is complicated and it is genuinely not.
Embed the player in your issue. Most hosts give you an embed code. Put the player at the top of the email version of your newsletter, above the written piece, so readers who would rather listen see the option before they start scrolling.
Keep the written version canonical. Your newsletter archive stays the primary version. The episode links back to it in the show notes. This avoids any confusion about which is the source of the record and gives listeners a way to find charts, links, and anything visual the audio could not carry. The same principle applies if you are converting a blog archive rather than a newsletter, covered in repurpose blog posts into audio in minutes.
Total setup: an afternoon the first time, then a few minutes per issue.
Paid newsletters: the private feed question#
If you run a paid tier, this is where it gets more interesting, and where the platform gap matters most.
A private podcast feed gives each paying subscriber a unique RSS URL they can add to their normal podcast app. Substack does this natively. Outside Substack, dedicated services exist specifically for gating podcast feeds behind a membership, and they integrate with common payment and membership systems.
Three configurations worth knowing, all of which work regardless of platform:
- Text free, audio paid. Everyone gets the written issue. Paying subscribers get the listenable version. You are paywalling convenience rather than ideas, which many writers find easier to justify to themselves and to readers.
- Both free, early access paid. Paying subscribers receive the episode first, and it opens publicly later.
- Free preview, full episode paid. A short free version gives non-paying subscribers enough to decide.
The reason audio works as a paid tier is that it does not require anyone to value your writing more highly than they already do. It asks whether they would rather listen than read, which is a question about their commute rather than about you.
Making the audio: three options#
Now the first problem, which is where most of the actual decision sits.
Record it yourself. Best when your voice and personality are part of why people subscribe. Nothing substitutes for someone who is genuinely good company in your ears. The honest cost is time: reading a 2,000-word essay well takes multiple takes, and editing takes longer than most people expect. If you have never recorded anything, our guide to starting a podcast with no equipment covers doing it with a phone and a closet, no purchases required.
Use a text-to-speech narration tool. Substack includes one. Standalone tools exist for everyone else. This reads your written words aloud, in order, in one voice. It is fast, cheap, and appropriate for short posts, conversational writing, and accessibility.
Convert to a restructured conversational episode. This rewrites the piece for listening rather than narrating it. Worth it when your issues are long or analytical, and when you want the audio to hold up as a podcast rather than as an accessibility feature.
Why narration often disappoints#
Worth understanding before you pick, because this is the most common reason people try audio once and abandon it.
Newsletters are written for the eyes. They use subheadings, bullet lists, bold text, pull quotes, and links to signal structure, and readers navigate that structure visually, skimming ahead and glancing back. None of that survives being read aloud. The listener cannot see where they are in the piece, cannot skim, and cannot flip back when they lose the thread.
There is also a memory problem. Spoken information is transient: once a sentence has passed, it is gone unless the listener was holding it in working memory. Long sentences with subordinate clauses and parenthetical asides, which read elegantly on a page, are genuinely hard to follow when they arrive once, at someone else's pace, while the listener is driving.
This is why a narrated essay frequently loses people around minute three even when the writing was strong. The content was fine. The format conversion never happened. Something was read aloud, but nothing was rewritten for the ear.
The practical implication: match the option to the writing. Short and conversational newsletters narrate well. Long analytical ones usually need restructuring, or they need you to read them yourself with the pacing and emphasis a human naturally adds.
Cadence: the thing that actually decides this#
The failure mode for newsletter podcasts is not audio quality. It is stopping.
An audio edition attached to a newsletter inherits your newsletter's cadence, which means you have just committed to producing audio every week or every fortnight, indefinitely, on top of the writing you already do. That is the real cost, and it is worth being honest with yourself about it before launching rather than after episode five.
Three ways to make it survivable:
Do not commit to every issue. An audio edition of your best monthly piece is more sustainable than a weekly obligation you resent by March, and subscribers do not mind. Announce it as a monthly deep-dive rather than promising something you will quietly stop.
Batch it. Whatever your production method, doing four at once takes considerably less than four times doing one, because the setup cost is paid once.
Pick the method you will still be using in six months. If recording yourself means each issue takes two extra hours, be realistic about whether that survives a busy quarter. The best method is the one that still happens when you are tired.
What to measure#
Two numbers tell you whether this is working, and downloads is not one of them.
Completion rate. Podcast hosts report this. It tells you whether people finish, and where they stop. If everyone leaves at four minutes, your intro is too long or the format is not landing.
Whether audio listeners are people who were not reading. This is the actual question. If your audio is being consumed entirely by people who already read every issue, you have added work without adding reach. If it is reaching subscribers who have gone quiet, it is doing its job. A one-question poll to your list answers this faster than any analytics dashboard.
For paid newsletters, add conversion: whether the audio tier is bringing in upgrades, and whether audio subscribers churn less than text-only ones.Once the audio edition is running, the tactics that bring in listeners beyond your existing list are in how to grow a podcast audience without ads.
Where Sprep fits#
We build a document-to-podcast tool, so treat this as an interested party talking.
Sprep converts newsletter issues you have already written into two-host conversational episodes rather than narrating them. One voice asks the questions your reader would have asked; the other delivers your argument, which is what addresses the transience problem described above, since questions create natural checkpoints for a listener whose attention drifted.
Every word of the script is editable before any audio renders, which is what makes an episode publishable under your own byline rather than something that approximately sounds like you. You can fix phrasing, correct pronunciation of names and acronyms, and add a spoken call to action pointing back to the issue. An approved script can also be generated in over 70 languages if your list spans countries.
It produces the MP3. You still need hosting and a feed, which means the platform section above still applies, and it fits into the wider approach in our guide to content repurposing.
Where it is the wrong choice. If subscribers are there for your actual voice, record yourself. If your newsletter is short and conversational, a plain narration tool is genuinely sufficient and cheaper. And if an issue was unclear in writing, conversion produces a clear recording of unclear thinking, since the format change is faithful to what you give it.
FAQ#
How do you turn a newsletter into a podcast? You need to solve three things: creating the audio file, hosting it with a valid RSS feed, and submitting that feed to Apple Podcasts and Spotify. Substack and beehiiv handle hosting and distribution natively. On Ghost, Kit, Mailchimp, Buttondown, or MailerLite you will need an external podcast host, which is a one-time setup of roughly an afternoon.
Can you host a podcast on your newsletter platform? It depends on the platform. Substack includes full podcast hosting with automatic RSS distribution and private subscriber feeds. beehiiv added podcast hosting in its late-2025 release. Most general email platforms do not, though many let you embed an audio player in a post, which reaches email readers but does not create a podcast feed.
What is the difference between embedding audio and having a podcast? An embedded player reaches people who open your email or visit your site. A podcast is an RSS feed submitted to platforms like Apple Podcasts and Spotify, which reaches people in the apps where they already listen. Embedding is easier, but it does not put you in someone's podcast queue.
Should you narrate your newsletter or restructure it? Match the method to the writing. Short, conversational newsletters narrate well. Long or analytical pieces often lose listeners when read aloud, because written structure such as subheadings and bullet lists does not survive narration, and spoken information cannot be re-read the way text can.
Can you make the podcast version paid and keep the newsletter free? Yes, and it is one of the more effective configurations. Substack supports this natively, and dedicated private-feed services provide the same capability on other platforms. It works because you are paywalling convenience rather than ideas, which is an easier task than charging more for the same writing.
How do private podcast feeds work for paid subscribers? Each paying subscriber receives a unique RSS URL they add to their normal podcast app, so episodes appear alongside everything else they listen to. Access is tied to their subscription status, so cancelling removes access to paid episodes.
How long should a newsletter podcast episode be? Match the underlying issue rather than a target length. A 2,000 word piece typically becomes ten to fifteen minutes, which fits most commutes. Whether it holds attention depends far more on whether it was restructured for listening than on total runtime.
Do you have to produce audio for every issue? No, and committing to it is the most common reason people stop. An audio edition of one strong piece per month is more sustainable than a weekly obligation that becomes resented, and subscribers respond fine to a clearly announced monthly format rather than an inconsistent weekly one.
How much does it cost to turn a newsletter into a podcast? Hosting can be free on entry-level tiers with storage limits sufficient for a first season. If you record yourself, the cost is time rather than money. Conversion tools and narration tools vary, and several including ours offer a free tier that covers one episode, which is enough to test whether your audience responds before committing.
How do you know if the audio version is working? Track completion rate rather than downloads, since a download does not mean anyone listened. More importantly, find out whether your listeners are people who were not finishing the written version. If audio is only reaching subscribers who already read every issue, you have added work without adding reach.
Turn one issue into an episode#
If you want to test whether your subscribers listen before committing to a production schedule, the free plan converts one issue you have already sent into a full episode of up to 15 minutes, with the script editor included so you can fix every word before any audio is generated.
