Substack Paywall Explained: Can You Read Paid Posts for Free, and What Actually Works

Substack links are among the most common URLs pasted into our reader, and the answer to "can I read this for free" depends entirely on one thing: whether the writer marked the post as free or as paid. Free posts open in full. Paid posts do not, through this reader or any other, because Substack never sends the paid part of a post to anyone who is not a subscriber. This post explains the mechanism, shows what our tests found, and lists the legitimate ways to read more of a Substack you like without paying.

Why tools cannot open paid Substack posts

Many magazine paywalls are enforced in the browser: the full article is in the page and a script hides it. Substack is different. When a writer marks a post as for paid subscribers, Substack publishes a public preview, usually the first few paragraphs, and keeps the rest on its servers. The paid portion is sent only to subscribers, by email and on the site when they are logged in.

That means there is nothing for a reader, an archive copy or a browser extension to recover. Our reader fetches the same page a search crawler sees, which is the preview, and marks the result as partial. Newsletters that run on Substack under their own domain, such as The Free Press and The Bulwark, behave the same way, because the custom domain is only a label on top of Substack's platform. Both serve teasers in our audits, which is exactly what you would expect.

The explainer on metered versus hard paywalls covers the general distinction, and paid Substack posts belong with the other sites that cannot be bypassed.

Our tests on 13 October 2026

• A free essay on a personal Substack loaded in full: 1,863 words in 41 paragraphs.
• A free local-news scoop on a neighbourhood Substack loaded in full: 463 words in 8 paragraphs.
• A free research note loaded in full: 281 words in 13 paragraphs.
• A paid post on michaeljburry.substack.com returned only its 104-word public preview and was flagged partial.

The pattern is clean. Free posts work every time, and paid posts stop where the preview stops.

How the Substack paywall works for readers

Substack is a newsletter platform, not a publication. Each writer runs their own newsletter and decides, post by post, whether it goes out to everyone or only to paid subscribers. Readers can subscribe for free to receive the free posts, or pay the writer a monthly or annual fee set by the writer to receive everything. A paid post still has a public web page, but it shows only the preview and a subscribe button to anyone who is not logged in as a paying subscriber.

Because the decision is made per post, the same newsletter can be mostly free with the occasional paid piece, or mostly paid with a free post now and then. Looking at the writer's archive page tells you quickly which kind you are dealing with.

Free ways to read Substack

Free posts and previews

Everything the writer has marked free is on the web for anyone, and loads in full through the reader if you prefer a clean layout. The public preview of a paid post is also free, and for shorter posts it can be most of the piece.

Free trials and comped subscriptions

Many writers offer a free trial of the paid tier, usually advertised on the subscribe page, and some give away comped subscriptions to readers who ask or who cannot afford the fee. Students in particular are often unlocked on request. Check the writer's About page or the footer of a recent post.

Ask the writer

Substack makes it easy to reply to a post or message the writer directly, and a surprising number will unlock a single post for a reader who asks politely. Writers also sometimes make an older paid post free after a while, so checking back is worth a try.

The Substack app and Notes

The Substack app has a free feed of posts from newsletters you follow, and Substack Notes is a free short-form feed where writers often summarise or excerpt their paid work. Neither gives you the paid text itself, but both are a good way to follow a writer at no cost.

Newsletters and magazines that do work

The contrast with Medium is instructive. Medium's member-only stories are enforced in the browser rather than on the server, which is why our Medium guide shows full stories loading. Among opinion and long-form magazines that cover similar ground to many political and cultural Substacks, Quillette, UnHerd, The Fence, Heatmap and New Left Review all load in full. See our complete list for the rest.

The honest recommendation

If you read a particular Substack every week, pay for it. Substack writers keep most of what you pay, and a paid subscription is the thing that lets them keep writing. If you only want the occasional piece, read the free posts and previews, take a free trial, or ask. Any site that claims to open paid Substack posts for anyone in 2026 is either showing you the same preview we get or is using a subscriber's login.
