Substack vs Medium: Which Platform Should You Choose?

Substack and Medium are both platforms where writers publish and get paid. But they take fundamentally different approaches to almost everything — audience ownership, monetization, content discovery, and the relationship between writer and reader.

Choosing between them isn’t about which is “better” — it’s about which model matches how you want to build your writing career.

The Core Difference

Substack is email-first. Your content goes directly to subscribers’ inboxes. You own the subscriber list. Your relationship with readers is direct and unmediated.

Medium is platform-first. Your content lives on Medium’s website, discovered through Medium’s algorithm. You share readers with the platform. Your relationship with readers is mediated by Medium’s feed.

This single distinction cascades into every other difference.

Audience Ownership

Substack

You own your subscriber list. You can export every email address at any time. If you leave Substack, your subscribers come with you. No one can change your distribution — when you hit publish, every subscriber gets the email.

Medium

You don’t own your audience in the same way. Medium has followers, but you can’t export their email addresses. Medium’s algorithm determines which followers see your content in their feed. If Medium changes their algorithm, your reach changes overnight.

Medium does allow you to export your stories and profile data, but not your followers’ contact information.

Winner: Substack, decisively. Audience ownership is the single most important asset for a long-term writing career.

Monetization

Substack

Revenue comes directly from your readers through paid subscriptions. You set the price, you keep 87% (after Substack’s 10% and Stripe’s ~3%), and you have a direct financial relationship with your audience.

Revenue is predictable — you know how many paid subscribers you have and what they pay.

Medium

Revenue comes from the Medium Partner Program. Medium pays writers based on “member reading time” — how long paying Medium members spend reading your stories. You don’t set a price or know exactly how much each reader is worth.

Revenue is variable and algorithm-dependent. A story that goes viral earns thousands; a story that doesn’t get algorithmic distribution earns pennies.

Winner: depends on your situation. Substack for predictable, relationship-based revenue. Medium for writers who want to be paid based on performance without asking readers to pay individually.

Content Discovery

Substack

Discovery happens through:

• Substack’s recommendation network (other writers recommend you)
• Notes (Substack’s social feed)
• Search engines (your posts are indexed)
• Your own promotion (social media, word of mouth)

Substack’s discovery is growing but still limited compared to Medium. You’re largely responsible for finding your own audience.

Medium

Discovery is Medium’s strength. The platform has millions of active readers, and its algorithm surfaces content to potentially interested users through:

• The homepage feed
• Topic pages
• Related story recommendations
• Medium’s email digest
• Search within the platform

A well-written story on a popular topic can reach thousands of readers without any external promotion.

Winner: Medium for discoverability. Substack for control over who sees your content.

Writing Experience

Substack

A clean rich text editor with basic formatting. No markdown support natively. Simple but sometimes limiting. If you write in markdown, tools like DownStack bridge the gap by converting markdown to Substack-ready rich text.

Medium

A polished, distraction-free editor that’s widely praised. Supports rich embeds, image galleries, and a smooth writing experience. More formatting options than Substack, including drop caps and section breaks.

Winner: Medium has the better native editor experience.

SEO

Substack

Each post gets a web page on your yourname.substack.com domain (or custom domain). The page is indexable and benefits from Substack’s domain authority. You have limited control over meta tags and no control over page structure.

Medium

Posts are published on medium.com, which has extremely high domain authority. Medium stories frequently rank well in Google. However, the SEO equity belongs to medium.com, not to you.

Winner: Medium for immediate search visibility. Substack for building your own domain’s authority (especially with a custom domain).

Community Features

Substack

• Comments: per-post comment sections
• Notes: a social feed for short-form content
• Chat: community messaging for paid subscribers
• Threads: discussion threads on posts

Medium

• Responses: comment-like responses that are themselves published stories
• Claps: appreciation signals (up to 50 per reader per story)
• Lists: curated collections of stories
• Publications: group blogs on specific topics

Both platforms offer community features, but Substack’s are more oriented toward direct writer-reader interaction, while Medium’s are more oriented toward a reader community browsing content.

Who Should Choose Substack

• Writers who want to build a direct relationship with their audience
• Writers who plan to monetize through subscriptions
• Writers who want to own their subscriber list permanently
• Writers who value predictable revenue over viral potential
• Niche writers with a specific audience willing to pay for expertise
• Writers who want a newsletter business, not just a writing outlet

Who Should Choose Medium

• Writers who want maximum discoverability without building an audience first
• Writers who prefer performance-based pay over subscription management
• Writers who want to reach general audiences on varied topics
• Writers who prioritize the writing experience and don’t need email delivery
• Writers testing ideas before committing to a paid newsletter
• Hobbyist writers who want to earn something without business management

The Hybrid Approach

Many writers use both. They publish on Medium for discovery and on Substack for relationship building. The workflow: write on Medium to attract readers, then funnel interested readers to a Substack newsletter for ongoing engagement.

This works but requires managing two platforms, which doubles the publishing effort.

Key Takeaways

• Substack is email-first with direct audience ownership; Medium is platform-first with algorithmic distribution
• You own your Substack subscriber list; you don’t own your Medium follower list
• Substack revenue is predictable (subscriptions); Medium revenue is variable (reading time)
• Medium has stronger content discovery; Substack gives you more control
• Medium’s editor is more polished; Substack’s is simpler
• Choose Substack for a newsletter business; choose Medium for maximum reach without audience management
• A hybrid approach (Medium for discovery, Substack for retention) is viable but labor-intensive
