What Substack Actually Is (From Someone Who's Run a Paid Newsletter)
I've published on Substack for a few years - started free to build a readership, then flipped a slice of it to paid. So this is written from the operator's chair, not Substack's marketing copy. Substack is a newsletter platform with billing bolted on. You write posts, they go out by email and also live on your Substack page, and you can put a paywall in front of some of them. Readers pay monthly or yearly; Substack collects the money, sends the emails, and pays you after taking its cut. That's the whole pitch: write, and the rest is handled.
The part that pulled me in is the zero-risk start. There is no monthly fee, no subscriber cap, no feature gate. You can run a free newsletter to 50,000 readers and pay nothing. Only when someone pays do you part with money - 10% of that subscription, plus Stripe's processing of about 2.9% and $0.30 per charge. On a $10 subscriber you keep roughly $8.41. The 10% never drops, no matter how big you get.
How People Actually Make Money On It
Substack is a publishing-and-billing tool, not a crowd. The income comes from the audience you bring and the wall you put up:
- Paid newsletters around a niche. This is the core play. Pick a topic people will pay to follow - AI tool breakdowns, market commentary, a trade newsletter - and charge $5-15/month. A writer with 2,000 free readers and a 5% paid conversion has 100 paying subs at $8 = $800/month, before scaling. The recommendation network (more on that below) is what makes cold starts possible.
- Founding-member and annual tiers. Offer a $100-250 founding tier for superfans and push annual billing. Annual cuts Stripe's $0.30 fee from 12 charges to 1, so each annual sub nets you a few dollars more - and annual readers churn less.
- Bundle audio and video. Substack hosts podcasts and video posts under the same paywall. Creators add a paid podcast feed or weekly video without a second platform. It will not replace a real podcast host, but for a writer adding audio as a bonus it is free and good enough.
- Chat community as a paid perk. Paid subscribers get a Substack Chat space - threaded discussion, basically a light Discord. Bundle it with the newsletter at $15-25 and you get recurring income that one-time product sales (covered on this site under Gumroad) cannot match.
The Recommendation Network Is the Real Growth Engine
Most platforms leave you to find readers yourself. Substack does not. Its recommendation system cross-promotes publications: when a reader subscribes to a writer you recommend, they are nudged to subscribe to you too. For a lot of newsletters this drives 30-50% of new signups, and it costs nothing. Notes - Substack's short-post feed, like a quieter Twitter - pulls people back to your full posts. I have watched a brand-new publication hit its first 100 paid readers almost entirely through recommendations and Notes, with zero ad spend. That network effect is the single best reason to start here instead of a flat-fee tool.
What Bugs Me (The Honest Cons)
- The 10% never shrinks. At $1,000/month paid you hand Substack $100. At $10,000/month that is $1,000 - $12,000 a year - with no volume discount and no way to negotiate it down. Flat-fee rivals (Ghost at $29/month, Beehiiv from $43/month) pass Substack on cost once you clear roughly $900/month in paid revenue.
- Design and branding are thin. Every Substack looks like a Substack. No drag-and-drop templates, no real theme control, limited meta-title and canonical control. If you care about a distinct brand or technical SEO, Ghost or a self-hosted setup beats it.
- Email tooling is basic. No drip sequences, no behavioral triggers, weak tagging, no proper A/B testing on subject lines. If you want marketing automation, this is the wrong tool - Kit or Beehiiv do that job.
- Analytics are shallow. You get open rates, subscriber counts, and basic revenue numbers. No cohort analysis, no click-maps, no revenue attribution by source. Fine for a writer, frustrating for a media operator.
- The app sits between you and readers. Substack keeps pushing its app and feed. App-only readers and Notes followers do not fully move with you if you leave. You can export your email list anytime (you own that), but the network does not follow.
Substack vs the Alternatives
| Platform | Fee model | Best at | Weak at |
|---|---|---|---|
| Substack | 10% of paid + Stripe | Zero-cost start, built-in reader network | Margin at scale, branding, automation |
| Gumroad | 10% + $0.50 + Stripe | One-off digital sales (files, prompts) | No recurring membership |
| Patreon | 10% + Stripe | Community memberships fans know | Discovery, email tools |
| Whop | 3% direct / 30% Discover | Gated communities and courses | 30% bite if Discover drives sales |
| Beehiiv | Flat $43/mo, 0% rev | Growth tools, analytics | No free built-in audience |
| Ghost | Flat $29/mo, 0% rev | Full control, SEO, branding | You build the audience yourself |
For a writer starting paid newsletters, Substack wins on cost and discovery. Once revenue is real, the math flips toward Ghost or Beehiiv.
Getting Started (What I'd Do)
- Start free, publish weekly. Pick one narrow topic and ship a useful post every week for two months. Build the list before you charge.
- Turn on recommendations early. Recommend 5-10 publications in your niche and accept reciprocals. This is free growth - do not skip it.
- Add one paid tier at $7-10/month once you have a few hundred engaged free readers. Keep most content free; paywall the deep or timely stuff.
- Push annual and founding tiers for your superfans to lift retention and fee economics.
- Re-evaluate at ~$900/month paid. If Substack's 10% now costs more than Ghost or Beehiiv's flat fee, move the hosting but keep the writing habit.
Bottom Line
Substack is the lowest-risk way to turn writing into recurring income. You pay nothing until readers pay you, and its recommendation network does discovery that no other newsletter tool gives away free. The trade is permanent: 10% of paid revenue forever, plus thin branding and weak automation. For a writer who wants to write and get paid, that is a fair deal. For a media business optimizing margin, move on once the numbers grow.
