You’re growing a list on Beehiiv — give it something to send

You moved to Beehiiv to grow: the recommendation network, boosts, segments, a clean editor that gets out of the way. But growth needs a reason to subscribe and a reason to stay, and that reason is consistent issues. Turning each episode into one means re-listening, digging for quotes, and writing from scratch — so the send slips, and the list you worked to build goes quiet.

Castmagic keeps the cadence. Drop in the episode and it comes back transcribed, then drafted into a full issue: an opening hook, the key takeaways, the sharpest quotes pulled word-for-word, and a clear call to action. Paste it into Beehiiv, drop in your blocks, and schedule — you’re editing a draft instead of staring at an empty editor.

Consistency is what compounds on Beehiiv

Beehiiv’s growth engine — recommendations, boosts, the network — rewards publications that keep showing up in the inbox. A list that hears from you every week opens more, refers more, and churns less; one that goes dark for a month is hard to restart. The hard part was never the platform, it was supply.

Repurposing solves supply. The episode you already recorded becomes the issue — same ideas, same guest, same lines — reformatted for the people who would rather read for five minutes than listen for an hour. The recording does double duty, and your send calendar stops depending on whether you found time to write.

A draft you can drop straight into the editor

Castmagic gives you a clean, formatted draft — headers, takeaways, and quotes already structured — so it pastes into Beehiiv’s editor and the formatting holds up. From there you add your blocks: a poll, a button, a subscribe prompt, your sponsor slot. No native publish button, and you wouldn’t want one — the last pass is yours.

Because it drafts from the verbatim transcript, the takeaways and pull-quotes are things actually said on the episode, not a generic summary. Save a prompt with your structure and tone as a recurring step, and every issue comes out in the same shape — ready for segments and your usual layout.

One episode, a full content week

The newsletter anchors the week, but the same recording is a multiplier. In one pass Castmagic can also draft a blog post for SEO, a LinkedIn post, an X thread, show notes, and pull short clips — so an hour of recording fills every channel you’re trying to grow, not just the inbox.

When you want to build something bigger than a single send — a welcome sequence or a lead magnet pulled from your best conversations — connect your library to Claude at castmagic.io/claude and work across the entire back-catalog at once.

Frequently Asked Questions

Last updated June 2026 by the Castmagic team

How do I turn a podcast episode into newsletter?

Add your podcast episode to Castmagic — paste a link or upload the file — it transcribes in minutes. Then choose the newsletter preset (or your own prompt) and Castmagic drafts it from the recording, in your voice. Edit it, drop in your links, and publish. The whole loop takes a few minutes instead of an afternoon.

Will the newsletter sound like me?

Yes — that's the point. Castmagic drafts from your actual words, and you can give it a custom prompt with your tone, structure, and rules (no hashtags, short sentences, your sign-off). Save it as a recurring prompt and every episode comes out on-brand. You stay the editor; it removes the blank page.

Can I repurpose my whole back-catalog at once?

For a single recording, the Castmagic app is the fastest path. When you want to work across your entire library at once — a lead magnet from your best episodes, a book, a course — connect Castmagic to Claude with the MCP connector and Claude can search and build from every recording you have. See castmagic.io/claude.

How accurate is the transcription it builds from?

Castmagic uses state-of-the-art speech models with 60+ languages, automatic language detection, and speaker labeling. Clear audio typically transcribes well above 95% accuracy, and a custom-vocabulary list keeps names, products, and jargon spelled right — so the content is built on a clean source.

Is it free to try?

Castmagic has a free tier so you can run a StreamYard recording through the full workflow and see the output. Higher volume — more recordings per week, longer files, and unlimited content generation — is on the paid plans.

Does this work with Beehiiv?

Yes — with the caveat that it’s paste-in, not one-click publish. Castmagic doesn’t connect to Beehiiv through an API; it hands you a clean, formatted draft. Copy it into Beehiiv’s editor and the structure holds up — headers, takeaways, and quotes land as blocks you can style, then add your buttons, polls, and subscribe prompts.

Can I match my newsletter’s existing format?

Yes. The default draft gives you a hook, takeaways, pull-quotes, and a CTA, but it’s a starting structure, not a fixed template. Write a custom prompt describing how your issue is laid out — sections, tone, sign-off — and save it as a recurring step so every episode comes out in your format.

How long can the episode be?

Full-length episodes are fine — Castmagic handles multi-hour recordings, and longer conversations usually make richer issues because there’s more to pull from. A typical hour transcribes in a few minutes, with speaker labels and timestamps so the right quotes are easy to find.
