Substack, For Marketers: A Quick Primer

What it actually is: A publishing platform that fuses a blog, an email newsletter, and a subscriptions/payments system. Content lives on a public web page and lands in inboxes simultaneously, so creators can publish articles, essays, podcasts, and videos, with Substack handling payments, subscriber management, and analytics so writers can focus on content.

The economics: Free to publish, free for readers on free tiers where Substack only takes a cut (10%) when you charge for paid subscriptions, on top of standard Stripe processing fees. On a $10/month tier, you'd net roughly $8.34 per subscriber after both cuts.

Beyond newsletters: It's grown into a mini social platform featuring Notes (a short-form feed similar to X), comment threads, group chats, and a recommendation network that surfaces your work to other creators' readers.

Why brands are showing up there: Businesses use it for thought leadership, customer education, employer branding, and building direct audience relationships outside algorithm-dependent channels. Think of it as owned media that also happens to have built-in discovery.
The trade-offs to know going in:
• Customization and email-marketing features are basic compared to dedicated ESPs or a full CMS
•Analytics are fine for directional tracking, not deep segmentation
•Substack's light-touch content moderation is worth weighing against the reach

Getting started, in brief: sign up → import any existing mailing list → set up branding under Creator Settings → connect Stripe under Payments → publish and cross-promote on your existing social channels → iterate based on opens/growth.

Substack is worth testing as a complement to your social strategy if you want a direct, algorithm-free line to a high-intent audience and are comfortable with basic tooling in exchange for built-in distribution and reader trust. It's not a replacement for a dedicated ESP or CMS if you need granular segmentation or brand-safe curation.

This is a trust-compounding channel, not a virality one, so be prepared to play the long game and give readers a reason to come back.
