Summary
Editor's update, July 2026: Web data applied via freshness queue
Substack is 'a new economic engine for culture' — a media platform for video, writing, podcasts, and creator-centered communities, all powered by subscriptions. Expanded beyond newsletter-only origins into multi-format media.
Direct subscriber ownership with organic recommendation-driven growth — publishers keep their email list and grow through peer recommendations, unlike all distribution-only platforms in this list.

FAQ
How is Substack scored?
Substack scores 3.6 out of 5 in Benchmark Grid's independent Best Email Newsletter Platforms benchmark. The overall figure blends capability (45%), publisher fit (40%) and cost of ownership (15%). Capability is itself a weighted average of 10 criteria; the heaviest are deliverability & inbox placement (16%), audience growth tools (12%) and segmentation & automation (12%). Vendors cannot pay for a score.
What size publisher is Substack built for?
Substack is built for small and local publishers and mid-market publishers. That is the vendor's own stated target, and it is one of the inputs to our publisher-fit score — a platform that suits a national newsroom often carries more operational load than a small one can absorb.
What does Substack cost?
Free to publish; Substack takes a 10% commission on paid subscription revenue plus standard Stripe processing fees. Our cost-of-ownership score is 3.5/5, which weighs pricing transparency, entry cost, implementation cost, hidden-fee risk and ongoing cost. Ask the vendor for a written first-year figure that includes implementation before you commit.
Who uses Substack?
We have evidenced 21 publishers running Substack. Adoptions are detected from site code, ads.txt records and published case studies rather than taken from the vendor's own customer list, and each one is listed on this page.
Can Substack pay for a better score?
No. Scores come from our editorial review of the product's documentation, demos and public evidence. A vendor can claim this listing or request a re-review, but nothing they buy changes a score or a position.
