From LinkedIn to Substack, thought leaders are investing in direct audience relationships.
For years, LinkedIn was the default stage for executive thought leadership. Post an insight, build a following, shape the conversation. It worked, until it didn’t.
According to the 2025 Algorithm Insights Report by LinkedIn researcher Richard van der Blom, organic reach on the platform dropped almost by 50% in a single year. Engagement fell 25%. Follower growth collapsed by 59%. A post that reached 10,000 people in 2024 now struggles to reach 4,000, with an identical audience. Company pages fared worse: organic reach for brand content fell between 60% and 66% from 2024 to early 2026.
The diagnosis isn’t complicated. Social media platforms are built to rent you an audience, not give you one. The moment algorithms shift, and they always shift, the reach disappears with them. The executives who figured this out first are the ones building newsletters.
Owned vs. Rented: The Strategic Distinction That Matters
The difference between a LinkedIn post and a newsletter isn’t format. It’s ownership.
When you publish on LinkedIn, Instagram, or X, your content enters a feed controlled by someone else’s algorithm. You might reach 5% of your followers. You might reach 25%.
A newsletter is different. When someone subscribes, they hand you their email address and give you permission to enter their inbox without an intermediary. That subscriber is yours. No algorithm decides whether they see your next edition.
This is the core shift driving executive newsletter adoption: the move from rented reach to owned audience.
LinkedIn now has over 500 million newsletter subscriptions globally, a 3x increase year over year, and 98% of the top 100 newsletters on the platform are written by individuals. Personal profiles generate 561% more reach than company pages posting identical content.
Why Newsletters Convert Where Posts Don’t
The case for newsletters isn’t just about distribution. It’s about what happens when your content actually reaches someone.
The 2024 Edelman-LinkedIn B2B Thought Leadership Impact Report, the sixth annual study of its kind, surveying nearly 3,500 management-level professionals, found that nearly three-quarters of decision-makers consider thought leadership more trustworthy than traditional marketing materials. More than 75% said a compelling piece of thought leadership prompted them to research a product or service they weren’t previously considering. And 60% said high-quality thought leadership revealed a significant business opportunity they had been missing.
A newsletter delivers that content with intent. Subscribers opted in. They expect insight. The reader isn’t scrolling past. They came to read.
LinkedIn or Substack: The Platform Decision
Most executives entering the newsletter space face the same early question: LinkedIn’s native newsletter feature, or an independent platform like Substack or Beehiiv?
The answer depends on what you’re optimizing for.
LinkedIn newsletters are built for discovery and professional reach. Every new edition triggers an email, push notification, and in-app alert to subscribers. New followers are automatically prompted to subscribe. Articles are indexed by Google, extending visibility beyond the platform. The trade-off: LinkedIn owns the subscriber list, the data, and the distribution rules. If the algorithm changes again, your newsletter isn’t immune.
Substack and Beehiiv offer what LinkedIn can’t: full ownership of the subscriber relationship. You export your list. You control the cadence, the design, the monetization. The platform doesn’t stand between you and your readers. The trade-off: no built-in professional network for initial discovery. Growth requires active audience-building from scratch.
The emerging consensus among strategists: use both. Build on LinkedIn for visibility and subscriber acquisition, its algorithm currently favors newsletter content over standard posts. Build on an independent platform for long-term ownership. Use LinkedIn to fill the top of the funnel; use Substack to own what’s inside it.
What Makes an Executive Newsletter Worth Reading
A newsletter isn’t a press release with a subscription button. Decision-makers can tell the difference.
The same Edelman-LinkedIn research found that less than half of decision-makers describe the overall quality of thought leadership they consume as good, and only 15% call it very good. The gap between volume and quality is wide. The executives who close it share three traits: they take a clear point of view, they back it with verifiable evidence, and they write as they think, not as their communications department would prefer.
The most-followed LinkedIn newsletters reflect this. Richard Branson’s Ask Richard, with 5.7 million subscribers, runs on a simple Q&A format and his unfiltered voice. Robert Glazer’s #Elevate, with more than 300,000 subscribers, publishes short reflective essays every week, 500 editions of consistent, personal leadership insight. Bill Gates’ Gates Notes draws 6+ million subscribers with genuine intellectual curiosity, not corporate messaging.
The pattern: individual voice, consistent cadence, real perspective. None of them sound like an investor relations update.
The Practical Starting Point
For an executive considering the move, the entry bar is lower than it appears.
LinkedIn requires 150 followers to activate newsletter features, a threshold most professionals already meet. Substack launches in minutes, for free. A biweekly cadence of 600 to 800 words is sustainable for most schedules and sufficient to build a meaningful presence.
The harder work is editorial discipline: choosing a lane and staying in it. The executives with the most-read newsletters aren’t trying to cover everything in their industry. They’re covering the part they see most clearly.
The Bottom Line
Thought leadership has always been about trust. The newsletter is simply the most direct path to building it.
Social platforms will keep adjusting their algorithms. Organic reach will keep declining. The executives who treat their audience as an asset to own, rather than a metric to chase, are the ones who will still have a direct line to decision-makers when the feed changes again.
Which it will.
