1
Transcribe the episode
Upload the finished episode and generate a full transcript with summary, key takeaways and standout quotes.
Why these tools
Castmagic handles transcription and repurposing in one place, so you do not need separate tools.
Expected output
A clean transcript, episode summary and a list of quotable moments.
2
Generate a first newsletter draft
Use the repurposing output to create a rough newsletter with a headline, short intro, 3 to 5 key takeaways and a link to the episode.
Why these tools
The draft is built from the transcript, so it stays faithful to what you actually said.
Expected output
A rough newsletter draft of 300 to 600 words.
3
Rewrite in your voice
Feed the draft and a few samples of your own writing into Claude and ask for a tighter, more personal version with 3 subject line options.
Why these tools
Claude gives the most natural writing and follows style samples well.
Expected output
A near-final newsletter with a personal intro and subject line options.
4
Proofread and finalize
Read it through once, check facts and links against the episode, and run it through Grammarly for typos and tone.
Why these tools
A quick polish catches mistakes and keeps the newsletter professional.
Expected output
A clean, ready-to-send newsletter.
5
Automate delivery and send
Set up an automation that creates a draft campaign in your email platform whenever a new episode is published, then review and schedule it.
Why these tools
Make.com removes the repetitive copy-paste and starts the process the moment an episode goes live.
Expected output
A scheduled newsletter that goes out the same day each week.
Complete Guide
BeginnerAbout 1 hour for first-time setup, then 30 to 45 minutes per weekThis workflow turns the episode you already made into a newsletter your audience will read. You do the creative work once, then reuse it. After the first setup, each weekly newsletter should take 30 to 45 minutes, mostly spent on reviewing and adding your personal touch.
Before you start
- ✓A published podcast episode or audio file
- ✓An email platform account (Mailchimp, Substack, Beehiiv or ConvertKit)
- ✓Two or three samples of your own writing for style reference
- ✓Free accounts for Claude and Make.com to get started
1
Transcribe the episode
Upload your episode audio file or paste your RSS feed link into Castmagic. Wait a few minutes for it to produce the transcript. Skim it for names, product terms and brand names that may be misspelled, and fix them now so the errors do not carry into the newsletter.
Example prompt
“Action: Upload episode-42.mp3 to Castmagic and select the transcript, summary and key quotes outputs.”
Pro tip
Upload the final edited audio, not the raw recording, so the transcript matches what listeners hear.
Common mistake
Skipping the transcript check and letting misspelled guest names slip into the newsletter.
2
Generate a first newsletter draft
Ask Castmagic to generate a newsletter or summary-style draft. Keep the structure simple: a catchy title, a two-sentence hook, three to five takeaways, one standout quote and a link to listen.
Example prompt
“Write a newsletter from this episode with a hook, 4 key takeaways, one memorable quote and a call to action to listen to the full episode.”
Pro tip
Keep a fixed newsletter template so readers know what to expect and you save time each week.
Common mistake
Sending the raw AI draft without editing, which makes the newsletter sound generic.
3
Rewrite in your voice
Paste the draft into Claude with a couple of samples of your writing. Ask it to match your tone, shorten it and write three subject lines. Add a personal note about what surprised you in the conversation.
Example prompt
“Here is a newsletter draft from my podcast and two examples of my writing. Rewrite the draft in my voice, keep it under 450 words, keep all facts accurate to the transcript, and suggest 3 subject lines under 50 characters.”
Pro tip
Save this prompt and your style samples in one note so you can paste them in every week.
Common mistake
Not providing style samples, which gets you bland, corporate-sounding text.
4
Proofread and finalize
Check every claim, name and link against the transcript. Then run the text through Grammarly to catch typos and tone problems. Send yourself a test email to see how it looks on mobile.
Example prompt
“Action: Paste the final text into Grammarly, accept the corrections you agree with, then send a test email to yourself.”
Pro tip
Read the newsletter out loud once. If it sounds unnatural when spoken, it will feel stiff to readers.
Common mistake
Trusting AI-generated quotes without confirming them against the real transcript.
5
Automate delivery and send
In Make.com, create a scenario with an RSS trigger for your podcast feed, and an action that creates a draft campaign in your email platform with the episode title and link. You still paste in the final text and schedule it, but the repetitive setup is done for you.
Example prompt
“Action: In Make.com, add the RSS 'Watch RSS feed items' module, connect your podcast feed URL, then add your email platform's 'Create a campaign draft' module and map the title and link fields.”
Pro tip
Choose a consistent send day, such as the day after your episode releases, so readers build a habit.
Common mistake
Trying to fully automate sending with no review, which risks publishing errors.
Pro tips from power users
- 01Include one exclusive extra in every newsletter, like a behind-the-scenes thought or a bonus link, so subscribers feel rewarded for signing up.
- 02Pull the best quote into a short standalone line at the top; it often improves open and click rates.
- 03Keep the newsletter short and point to the episode instead of replicating it entirely.
- 04Reuse the same structure every week so editing gets faster.
Frequently asked questions
Will the newsletter sound like me?
It will if you give Claude samples of your own writing and add a personal note yourself. Treat the AI output as a strong first draft, not the finished piece.
How much does this cost?
You can start almost free with Claude's free tier, Grammarly's free plan and Make.com's free plan. Castmagic is a paid tool at around $23 per month, so the budget alternative is worth trying first if cost matters.
Do I need to write anything myself?
Only a short personal intro or reaction and a final review. Most of the writing work is done by the tools.
Can I fully automate this?
You can automate the trigger and draft creation, but it is better to keep a human review before sending so mistakes and awkward phrasing do not reach subscribers.
Which email platform should I use?
Any of Substack, Beehiiv, Mailchimp or ConvertKit works. Pick the one that connects with Make.com and that you find easiest to manage, and start with the free tier.
Next steps
