So you want to repurpose your content from Substack to LinkedIn?
I get it. You’ve poured your heart into crafting thoughtful newsletters, but they’re mostly reaching the same audience over and over. Meanwhile, LinkedIn’s 900+ million professionals are scrolling by, completely unaware of your brilliant insights.
Maybe you’re hesitating because it feels like extra work. Or perhaps you’re worried about annoying your followers with repetitive content. Or maybe you just aren’t sure how to adapt your long-form Substack pieces for LinkedIn’s different format and audience.
Whatever’s holding you back, let’s break through that barrier today.
Why you should repurpose from Substack to LinkedIn
LinkedIn isn’t just another social media platform—it’s a professional powerhouse where thought leadership is currency. When you repurpose your Substack content there, you’re:
- Tapping into LinkedIn’s algorithm that actively promotes valuable written content
- Reaching potential subscribers who might never discover your Substack otherwise
- Building your personal brand in front of decision-makers and industry peers
- Creating multiple touchpoints with your audience across different platforms
The importance of repurposing content goes beyond just saving time. Truth is, you never really know what kind of content is going to resonate better on which platform.
Back in 2020, I created YouTube videos about note-taking that weren’t getting much traction. On a whim, I decided to repurpose those exact same concepts as written articles on Medium. The difference was night and day—those repurposed pieces exploded in popularity, helping me launch a profitable five-figure course and add 3,000 email subscribers to my list in just 12 weeks.
Why such different results? It comes down to audience preferences, platform algorithms, content format, and sometimes just pure timing. The lesson is clear: your valuable content deserves more than one chance to find its audience.
The main differences between Substack and LinkedIn
Before you start copy-pasting, understand that these platforms operate on different principles:
Substack:
- Long-form, typically 1,000+ words
- More intimate, conversational tone
- Built for deep dives and nuanced topics
- Readers are already opted-in and engaged
- Success measured in opens, clicks, and paid subscriptions
LinkedIn:
- Shorter content performs better (under 1,300 characters gets full visibility)
- Professional, value-driven tone
- Built for networking and professional development
- Readers are scrolling a feed, not specifically seeking your content
- Success measured in views, comments, shares, and profile visits
What makes good LinkedIn content
LinkedIn rewards content that generates conversation and provides clear value without requiring too much time investment.
The best LinkedIn posts typically:
- Start with a hook that grabs attention in the first 2-3 lines
- Use short, punchy paragraphs (often just 1-2 sentences)
- Include lots of white space for easy mobile reading
- Contain specific, actionable insights rather than general advice
- End with a thought-provoking question or clear call-to-action
For example, rather than saying “Email marketing is important for businesses,” a successful LinkedIn post might begin: “I sent one email yesterday that generated $13,427 in revenue. Here’s exactly how I wrote it…”
Build Your Swipe File Of Winning LinkedIn Content
The best way to create effective LinkedIn posts is to study what’s already performing well. Each platform has its own unwritten rules, so collect specific examples you can reverse-engineer.
PRO TIP: Focus on finding creators who are relatively new to LinkedIn but getting impressive engagement. The established influencers with 500K followers can post almost anything and get traction—their strategies won’t necessarily work for smaller accounts like yours. Look for people who’ve grown quickly from obscurity instead.
Yes, building this swipe file takes upfront work, but it will dramatically accelerate your results.

Simple workflow to turn Substack newsletters into LinkedIn posts
Okay, so now that you have these laid out…
You could either do this manually like a monkey.
Hire a VA that you need to train for weeks on Fiverr…
Or (my favorite way):
You could use AI and automation tools to make this process as smooth as butter.
Here’s an example:
As soon as you publish on Substack, it will automatically transform into a LinkedIn post. No extra work needed.
You can start creating automations that utilize specific prompts to save your time.
Tools like n8n, Make (formerly Integromat), or Zapier can set up these workflows easily. Here’s a simple one that’s working right now:
1. Set up a Zapier trigger that activates when a new Substack post publishes
2. Use the OpenAI connector to transform your content with this prompt:
“Transform the following Substack newsletter into a standalone LinkedIn post under 1,300 characters. Maintain the core insight but make it more concise, conversation-starting, and appropriate for LinkedIn’s professional audience. End with a thought-provoking question. Here’s the newsletter content: [CONTENT]”
3. Send the transformed content to you for review via email or Slack
4. After approval, automatically post to LinkedIn via Zapier’s LinkedIn integrations
This entire process takes about 10 minutes to set up once, and then runs automatically forever.
Stop letting your brilliant content gather dust in one corner of the internet when it could be working double-duty for your brand, reputation, and business.
