186 paid from a village in Thailand

One confirmed case this week. A Traditional Chinese Medicine doctor living in a rural village in northern Thailand — 186 paid subscribers, $40/year, publishing twice a week. That's roughly $1,300/month from a practice no Western health influencer could credibly replicate.

Two other candidates came close but didn't clear the qualifying bar: a funeral-industry trade newsletter that may already exceed 5,000 total subscribers, and a European theater newsletter sitting just under 100 paid. Both are profiled honestly below with the data gaps flagged. The research found what it found.

Milestone: 186 paid subscribers, disclosed publicly on May 30, 2026, in a Reddit thread asking Substack writers to share their niche and subscriber numbers. 1 The newsletter's homepage confirms "Over 4,000 subscribers." 2

Niche: Traditional Chinese Medicine integrated with personal dispatches from rural Thailand — TCM clinical knowledge made accessible to people who cannot afford or access one-on-one practitioners. The About page frames it directly: "for many of us, working one-on-one with a practitioner — or investing in programs, herbal medicines, or supplements — isn't always an option. And even when it is, no external treatment can replace what we do every day." 3

Author: Dr. Dana Leigh Lyons holds a Doctor of Traditional Chinese Medicine (DTCM) from a five-year program and is licensed in both the United States and Canada. She served as President and instructor at Pacific Rim College in Victoria, British Columbia — a licensed college of acupuncture and traditional Chinese medicine. She also holds a master's degree in Middle Eastern Politics from Georgetown University and a Primal Health Coach certification, and lives in a rural village in northern Thailand. 3 The credential stack is not decorative: she spent years in institutional TCM education before writing for a public audience.

Cadence and structure: Two posts per week, most weeks. 1 The newsletter divides into named series:

Free/paid split: The free layer handles the personal and the relational — the dispatches from Thailand that make a reader trust the author before they've read a word of clinical content. The paid layer holds the professional depth: the TCM Deep Dives and The Practice series are the reason a reader with a genuine interest in Chinese medicine would convert. The split is clean. Free content builds the audience; paid content justifies the price. 3

Conversion lever: No milestone announcement post exists — the public record of 186 paid is a single Reddit comment in a thread, not a celebration.

What's observable: the conversion rate is approximately 4.4% (186 ÷ 4,200), 1 which runs above the 2–3% baseline that most paid newsletters see from cold-audience subscribers. The explanation is almost certainly the specificity of the niche. Readers who find a newsletter about TCM written by a licensed doctor living in rural Thailand have already self-selected twice — they want TCM content, and they want it from a practitioner, not a wellness influencer. The subscriber who converts at $40/year is not impulse-buying; they have already decided this is the voice they want on this subject.

Revenue math: At the current 186 paid subscribers and $40/year pricing, annual revenue runs approximately $7,440. 1 At 500 paid — the channel's benchmark — that's $20,000/year on the annual plan, or $42,000/year if the mix shifts toward the $7/month option.

Reader application: Any licensed TCM practitioner, licensed acupuncturist (L.Ac.), or naturopathic doctor with clinical training in Chinese medicine who is writing for a general health audience is in directly comparable territory. The model also works for credentialed practitioners of other clinical traditions that are underrepresented in English-language professional media — Ayurvedic medicine, homeopathy, anthroposophic medicine — where the gap between professional depth and public-facing content is similarly large.

Newsletter: On Deathcare, run by Tony Russo (ondeathcare.substack.com). 4

Niche: Trade journalism for funeral directors and end-of-life care professionals — covering industry regulation, cremation trends, technology adoption, and consumer behavior shifts. Russo frames the positioning clearly: "Deathcare is changing rapidly and forever. While the catalysts seem obvious — technology, the rise of cremation, shifting consumer habits — the reality goes much deeper." 4

Author: Tony Russo is an independent journalist and podcast host based on Maryland's Eastern Shore with years of deathcare industry reporting. He publishes a Friday news digest and original reporting for free subscribers; paid subscribers receive a Sunday preview, a subscriber chat, and full archive access. Founding members get podcast access.

Why it didn't qualify: The homepage lists subscribers as "thousands" — a Substack-generated description that suggests total subscribers may already exceed the 5,000 cap this channel uses. No paid-subscriber count or milestone announcement was found in the public record. Both gaps are unresolvable without author disclosure. 4

Why it's worth watching: The funeral industry operates under state-by-state licensing requirements, and the trade press — Funeral Business Advisor, NFDA Funeral Home & Cemetery News — is largely behind association paywalls or print-first. A solo practitioner-journalist serving that community with a direct-to-reader paid model is structurally sound. If Russo's total count lands under 5,000 and he discloses a milestone, On Deathcare would be a straightforward qualifying case for a future issue.

Newsletter: Café Europa, run by Natasha Tripney (natashatripney.substack.com). 5

Niche: European theater — weekly criticism, artist interviews, festival coverage, and the cultural politics of European stages from an editor with two decades of access to the continent's main venues and companies.

Author: Tripney is the international editor of The Stage, the British theater trade paper, and previously its reviews editor and joint chief theater critic. She co-founded Exeunt, an online theater magazine, in 2011, and has written for The Guardian, BBC Culture, and The New York Times. She also edits SEEstage.org, a platform for theater criticism from Southeast Europe. 5 The professional access is real: Tripney reviews shows across Europe that English-language audiences rarely see covered by any outlet.

Why it didn't qualify: In a recent post, Tripney noted she has "just under 100 paid subscribers" — the milestone threshold is 100. The total subscriber count is listed as "thousands," which raises the same potential over-cap question as On Deathcare, though unconfirmed. 5

Why it's worth watching: European theater is nearly invisible in English-language arts coverage outside of London and Edinburgh. No competing paid solo-author Substack newsletter covers European stages. If Tripney crosses 100 paid — a conversion that would require fewer than ten additional subscribers from her existing readership — Café Europa qualifies cleanly.

This week's confirmed case and the two near-misses all sit at the intersection of deep professional credentialing and underserved public audiences. The pattern points at three adjacent niches where no dominant paid solo-author newsletter is visible on Substack.

Ayurveda — the traditional Indian medical system — is not represented by any newsletter in Substack's top 25 Health listings. 6 Small Substack presences exist (Everyday Ayurveda, Adiveda Newsletter), but none have reached leaderboard rankings. The National Ayurvedic Medical Association (NAMA) certifies practitioners at four professional levels; the Association of Ayurvedic Professionals of North America (AAPNA) serves the North American practitioner community. Reddit's r/Ayurveda has approximately 85,000 members. The audience for credible, clinical-grade Ayurvedic writing is large and has no clear dominant voice. A NAMA-certified Ayurvedic doctor writing for Western integrative practitioners — MDs, NDs, licensed acupuncturists — who want evidence-based frameworks for Ayurvedic principles would occupy the same structural position as PERFECT HUNGER in TCM. Revenue math at $12/month: 500 paid = $72,000/year.

Twenty-three US states, Washington DC, Puerto Rico, and the US Virgin Islands license naturopathic doctors (NDs — holders of a four-year naturopathic medicine degree). 7 Approximately 6,000 licensed NDs practice in North America, trained across eight CNME (Council on Naturopathic Medical Education)-accredited four-year medical programs. 7 No naturopathic medicine newsletter appears in Substack's top health rankings. The gap is specific: mainstream medical journals do not cover naturopathic clinical practice; naturopathic associations publish member-only content. A licensed ND at an Oregon or Washington practice — states where NDs have the broadest prescribing rights and can serve as primary care physicians — writing a newsletter that translates naturopathic research for MDs and integrative practitioners would have an audience with no existing destination. Revenue math at $15/month: 500 paid = $90,000/year.

The Association of Certified Fraud Examiners (ACFE — the credentialing body for the Certified Fraud Examiner, or CFE, designation) has more than 90,000 members globally. 8 Substack's business leaderboard top 25 includes no newsletter focused on fraud examination or forensic accounting. A handful of small presences exist — scattered posts on "forensic accounting as code," occasional case analyses — but no practitioner-led paid newsletter has captured the field. CFEs earn median salaries above $100,000; they read to stay current on case law, SEC enforcement trends, and emerging fraud typologies. An experienced CFE or CPA with a background in Big Four forensic accounting or financial crimes investigation, writing case-based analysis for internal auditors, compliance officers, and corporate counsel, would face essentially no competition. Revenue math at $15/month: 500 paid = $90,000/year.

Three issues in, the pattern is consistent: the newsletters that reach paid conversion milestones are written by people whose credential took years to build and whose specific niche has no comparable English-language voice. The research difficulty is part of the signal — a niche where a paid newsletter is easy to find already has one. The open fields are the ones where searching turns up nothing.
