What it does
Substack combines a publication website with email newsletters and optional paid subscriptions. Writers need an account, but publishing is free at any subscriber count; paid readership adds a 10% revenue share and separate Stripe fees.
Choose where the post should appear before publishing. A new article defaults to the web, email and the Substack app inbox; the publishing settings let the writer change the audience, schedule it or clear inbox delivery for a web-only post. Editing an emailed post later changes its web and app versions without resending the original email.
For an individual follow-up, filter the Subscribers view, select the intended people and use Send email. This direct message can be scheduled and appears with an email icon in the dashboard, but it does not create a post in the publication's public archive. A correction for a selected group can use that route when a web edit alone would not reach their inboxes.
Publishing is free regardless of subscriber count. Turning on paid subscriptions adds Substack's ten-percent share of subscription revenue plus Stripe's separate processing fees; the writer sets the subscription price.
To open a publication, choose Create account on Substack, set up the profile and select the plus sign, then Post. New publications are public by default. If the newsletter is intended for a private group, open Settings and enable Privacy mode before sharing it.
