Research brief: A newsletter platform for solo writers who want to earn from paid subscriptions

One idea, solo writers as the customer, 11 products. Eight came from the register; research added beehiiv, Ghost and Kit.

What we found: Paid newsletters for solo writers are held by large platforms whose cut runs from 10% (Substack) to 0% (beehiiv, Ghost). None of the six small register launches advertises paid subscriptions today; the one that did, Papyrus, left the market by 2022.
Why it matters: A new platform can't win on take rate: 0% already exists. The small entrants still running appear to have survived by narrowing to a writing workflow (Notion, WordPress, the inbox), not by competing on paid subscriptions.
Still uncertain: Two lineage links (Papyrus to Paragraph, Blogstatic to Blogmaker) are inferred, not announced, and beehiiv's figures come from a capture four days old.
Do next: Decide what writers would pay for that beehiiv and Ghost don't offer, and test it with writers who already earn from subscriptions before picking a fee model.

The findings in detail

beehiiv (from $49 a month billed yearly, per a 26 October capture) and Ghost (from $29 a month billed yearly) charge a flat plan and take 0% of subscription revenue. Substack is free to start but keeps 10%; Kit's free plan charges 3.5% + 30c per transaction, card fees included.
Of the six small register launches, none of the sites checked today advertises built-in paid subscriptions. The one that did, Papyrus (a 5% fee in 2021), had relaunched as a web3 platform by April 2022 and now redirects to Paragraph, which sells an AI content agent to companies.
The register entries still answering appear to have narrowed to a writing workflow (Notion, WordPress, the inbox) and charge by contacts, sends or a flat plan, not a share of revenue.
Others changed hands or shape: Twitter bought Posterous and closed it in 2013, Newsletter Glue was sold in April 2025, Blogstatic appears to have become Blogmaker, and IndiePaper's domain appears to have lapsed after 2022.

Who each sells to, and how it works

Substack: Writers and creators of all kinds.Paid subscriptions built in: 'Writers keep 90% of their revenue minus credit card fees.'
Notocat: Notion users: communities, personal blogs, client updates.No paid-subscription feature listed; charges writers by contact count.
Newsletter Glue: Now 'publishers, newsrooms, and media companies'.No built-in paid subscriptions; its own guide pairs it with a separate membership plugin and Stripe.Note: Appears to have moved from solo writers toward newsrooms.
Papyrus: Was bloggers and newsletter writers; now companies.In 2021, Stripe paid subscriptions 'after Papyrus takes a 5% fee'.Note: That Papyrus became Paragraph is inferred, not announced.
Blogstatic: Bloggers, writers and content marketers.Newsletters and email capture only; no paid subscriptions.
Weightless: People who want plain-text email without open tracking.No paid-subscription feature; a flat monthly plan.
IndiePaper: Self-publishing book authors.Sold ebooks and pre-orders, not subscriptions; an adjacent idea.Note: No source on what happened to the product, so it isn't called shut down.
Posterous: Not verified from a primary source.No paid-subscription model found in the sources checked.Note: Co-founder Garry Tan launched Posthaven as a successor.
beehiiv: Creators 'ready to grow faster and start monetizing'.Paid subscriptions from Lite up: 'beehiiv takes 0%', Stripe's 2.9% + $0.30 applies.
Ghost: Creators, writers, journalists and new media.Stripe paid subscriptions with 0% from Ghost; processor fees apply.
Kit (formerly ConvertKit): Creators: authors, bloggers, newsletter writers.Paid newsletters on all plans at 3.5% + 30c per transaction, card fees included.

What remains unknown

Whether Papyrus and Paragraph are the same company; inferred from the redirect and an image bucket named 'papyrus_images', with no announcement. Blogstatic becoming Blogmaker is likewise unannounced.
beehiiv's price and fee come from an Internet Archive capture of 26 October 2026; the live site blocked automated checks.
That Notocat, Weightless and Blogmaker lack paid subscriptions is judged from their public pages only, not from inside the products.
What happened to IndiePaper as a product; only its domain's history is documented.

What to find out next

Choose the fee model before building. Writers can already keep 100% of subscription revenue (minus Stripe fees) on beehiiv Lite or Ghost Publisher, so a percentage cut has to be justified by something other than price.
Interview solo writers who already charge readers on Substack, beehiiv, Ghost or Kit about what would make them move a paying list.
If you take a workflow wedge (Notion, WordPress, the inbox), check whether its users want paid subscriptions at all; none of the register's wedge products advertises them.
