If you have been researching Substack and spotted its 1.4-star Trustpilot rating, you might be wondering whether something is seriously wrong with the platform. That score does reflect real problems – mainly poor customer support and billing cancellation issues – but it is drawn from a tiny sample of around 150 reviews on a platform used by millions of writers and readers worldwide. The fuller picture is considerably more positive.

Substack is a legitimate, well-funded publishing platform that has paid out approximately $450 million to writers in 2025 alone, crossed a $1.1 billion valuation in its July 2025 Series C funding round, and has more than 50 writers earning over $1 million per year through paid subscriptions.

It is genuinely one of the most creator-friendly newsletter platforms available in 2026. The honest caveats are about income reality and support quality – not about whether the platform is trustworthy.

What is Substack and how does it work?

Substack was founded in October 2017 by Chris Best, Hamish McKenzie, and Jairaj Sethi in San Francisco. Its founding premise was simple: give writers a direct path to earning from their audience without advertising, editorial gatekeepers, or algorithmic throttling.

The business model it introduced – subscription revenue shared directly between platform and writer – has since shaped how most independent publishing platforms think about creator economics.

In 2026, Substack is considerably more than a newsletter tool. It hosts text posts, podcasts, video, live streams, and a short-form feed called Notes that functions as an in-platform social network.

Writers can publish free content to build an audience, gate premium content behind a paid subscription, or do both simultaneously. Readers subscribe – either for free to receive posts in their inbox, or by paying a monthly or annual subscription fee for access to paid-tier content. Substack takes 10% of all paid subscription revenue; writers keep 90% minus Stripe processing fees.

One of Substack’s genuine competitive advantages over most creator tip-and-support platforms is its built-in discovery infrastructure. The Notes feed – Substack’s short-form social layer – uses an algorithm to surface content to people who do not yet follow you.

The Recommendations network lets established writers recommend newer ones to their audiences. This means Substack is one of the few newsletter platforms where organic audience growth is possible without external social media promotion, though building from zero still takes significant time and consistency.

The economics of Substack scale well at the right audience size. At 1,000 paid subscribers paying $10 per month, a writer grosses $10,000 monthly and keeps approximately $8,700 after Substack’s cut and processing fees.

At 100 paid subscribers at the same price point, monthly net is around $870. The threshold most writers describe as “life-changing” – enough to replace a full-time salary – sits at roughly 1,000 paid subscribers at $8 to $10 per month. Getting there is the hard part.

Is Substack legitimate? What the evidence shows

Substack is legitimate. It is a real, well-funded US company with institutional backing, a verified payout record, and a product that has demonstrably helped thousands of writers build sustainable income from their work. The evidence for this is not anecdotal – it is in the funding history, the published revenue figures, and the independently reported earnings of writers on the platform.

The 44% average email open rate is worth pausing on. Industry standard open rates for commercial newsletters hover around 20% to 25%. Substack’s double-digit advantage reflects a structural reality: subscribers who actively choose to pay for or follow a specific writer are far more likely to read what that writer sends than someone on a commercial marketing list. That attention is the economic foundation of everything Substack writers build.

The funding trajectory also matters for the legitimacy question. A company that raised $100 million in Series C funding in July 2025 at a $1.1 billion valuation – with institutional investors who have done due diligence – is not a fly-by-night operation.

Substack has been independently audited, has transparent public financials available through press reporting, and has a CEO who gives on-record interviews citing specific platform metrics. This is what a legitimate business looks like.

What about the 1.4-star Trustpilot rating? Here is the full context

Substack’s 1.4-star Trustpilot score is real and should not be dismissed – but it needs context to be interpreted correctly. That score comes from approximately 150 reviews. Compare that to Buy Me a Coffee (1,400+ reviews at 3.5 stars) or OnlyFans (4,000+ reviews at 1.3 stars). The sample size is too small to be statistically representative of a platform used by millions of writers and readers.

Looking at what the Trustpilot complaints actually say, the dominant themes are:

• being charged multiple times for the same subscription without being able to reach human support to fix it;
• difficulty cancelling a paid newsletter subscription due to unclear UI;
• getting stuck in automated support loops with no human resolution;
• and account access problems when two-factor authentication fails.

Several writers also report random automated account suspensions for alleged spam when their content clearly does not qualify.

These are genuine problems. Substack’s customer support is a documented weakness – TechRadar’s 2025 review estimated that only around 10% of support callers reach a human agent, and the primary support channel is an AI chatbot that users consistently describe as inadequate for anything beyond basic questions.

For a billion-dollar company, the support infrastructure is not where it should be. That said, the nature of these complaints – billing glitches and support access – is meaningfully different from a platform committing financial fraud against its creators.

How much can you realistically earn on Substack?

The headline earnings on Substack – more than 50 writers earning $1 million or more per year, the top 10 newsletters collectively generating $40 million annually – are real and verified. But the distribution behind those numbers is severely skewed, and understanding where most writers actually sit is essential before you invest significant time in the platform.

What do real users say about Substack in 2026?

Across Product Hunt, Reddit, and independent creator communities, the Substack experience divides cleanly along two axes: how writers feel about the product and platform, and how frustrated they are with support. The writing and publishing experience consistently draws praise. The support experience consistently draws criticism. Here are two representative creator experiences.

Is Substack worth it – honest verdict

For writers who are willing to publish consistently, have something genuinely valuable to say, and are patient enough to let the compounding mechanics of the Recommendations network do their work, Substack is one of the best platforms available in 2026. The 10% fee is competitive compared to alternatives at similar revenue levels.

The built-in discovery tools – Notes, Recommendations, search – are a genuine advantage that most competing newsletter platforms do not offer. And the 44% average email open rate means the audience you build is unusually engaged.

The honest limitations are two: the income curve is heavily concentrated at the top, meaning most writers earn modestly or nothing for an extended period before seeing meaningful revenue; and the customer support is poor enough that billing and account access problems can take weeks to resolve.

Neither of those is a reason to avoid Substack – but both are reasons to go in with realistic expectations and protective habits around account security and billing monitoring.

Who should use Substack – and who needs a different approach?

Substack excels in specific situations and falls short in others. Here is a clear breakdown based on the evidence above.

Want income that does not require 18 months to build? Here is how AliDropship works

Substack is one of the best long-term income platforms available to writers – but it is slow to build and entirely dependent on the quality and consistency of your writing output.

AliDropship works on a different timeline: a fully built ecommerce store with 100+ products pre-loaded, one-click advertising that can generate sales from day one, and a free Amazon Seller Kit that opens 300 million buyers immediately – no writing, no publishing schedule, and no 18-month audience build required.
