Two Platforms, Two Philosophies
Substack and Medium have both become popular homes for independent writers — but they operate on fundamentally different models. Understanding how each works helps you align your platform choice with your actual goals.
What Is Substack?
Substack is a newsletter-first platform. Writers build subscriber lists and send posts directly to readers' inboxes. You can offer free and paid tiers, with Substack taking a percentage of paid subscription revenue. Importantly, you own your subscriber list — if you leave, you take your audience with you.
What Is Medium?
Medium is a publishing platform built around discovery. You publish articles, and Medium's algorithm distributes them to readers through its internal feed and the Medium Partner Program. Readers pay a monthly subscription to Medium, and writers earn a share based on how much time subscribers spend reading their content.
Head-to-Head Comparison
| Feature | Substack | Medium |
|---|---|---|
| Primary format | Email newsletter | Web articles |
| Built-in audience | No — you grow your own list | Yes — discovery via Medium's platform |
| You own your audience | Yes | No |
| Monetization model | Paid subscriptions (you set price) | Revenue share from Medium's paywall |
| Substack's cut | 10% of subscription revenue | N/A |
| Custom domain | Yes | No (on standard plan) |
| SEO potential | Limited | Moderate (via Medium's domain authority) |
Substack: Best For Building a Direct Audience
Substack's biggest strength is the direct relationship between writer and reader. Email subscribers are the most engaged audience you can have — they've opted in and your content arrives in their inbox without competing with an algorithm.
Substack works best if you:
- Want to build a loyal, owned audience over time.
- Plan to monetize through paid subscriptions.
- Write regularly on a specific topic that readers will pay to follow.
- Value independence and audience ownership above all else.
The challenge: You're responsible for your own growth. Without an existing audience, building on Substack requires active promotion across social media and other channels.
Medium: Best For Discovery and Getting Read Quickly
Medium's built-in distribution is genuinely powerful. Well-written articles can find a large audience quickly through Medium's recommendation engine, curated publications, and search traffic — without you needing to promote your work extensively.
Medium works best if you:
- Want to get your writing in front of readers quickly without building a following first.
- Write broadly appealing content (personal essays, general how-tos, opinion pieces).
- Want passive income from writing without managing paid subscriptions.
- Are experimenting with writing topics and don't yet have a defined niche.
The challenge: You don't own your audience. Medium can change its algorithm, payment rates, or policies at any time, which affects your reach and earnings.
Can You Use Both?
Yes — many writers publish on Medium for discovery while simultaneously building a Substack list for their most engaged readers. You can cross-promote between platforms: include a Substack signup link in your Medium bio or articles, and over time convert casual Medium readers into loyal newsletter subscribers.
The Bottom Line
If long-term audience ownership and sustainable direct revenue are your goals, Substack is the better foundation. If you want to start getting read immediately with minimal audience-building effort, Medium lowers the barrier to entry. Many serious writers find value in starting with Medium to build confidence and an early readership, then transitioning their core audience to Substack over time.
