How to Start a Substack Newsletter: The Complete Setup Guide

Getting Started

Starting a newsletter on Substack is straightforward — the platform handles hosting, email delivery, payments, and subscriber management out of the box. But the decisions you make during setup shape your publication’s trajectory. Choosing the right niche, configuring settings correctly, and publishing a strong first post set the foundation for everything that follows.

This guide walks through the entire process from zero to published, including the strategic choices that most setup guides skip.

Why Substack

Before diving into the how, it’s worth understanding why Substack specifically. The platform offers a combination that’s hard to match:

Free to start: no monthly fees until you turn on paid subscriptions
Built-in audience tools: recommendations, notes, and cross-promotion with other writers
Email delivery handled: Substack manages deliverability, unsubscribes, and compliance
Web presence included: every publication gets a website with SEO-friendly pages
Payment processing: Stripe integration for paid subscriptions is built in
Content ownership: you can export your subscriber list and content at any time

The trade-off is Substack’s 10% cut on paid subscriptions (plus Stripe’s processing fees). For most writers starting out, the free tools and audience features more than justify this.

Step 1: Define Your Niche and Audience

The most important decision isn’t technical — it’s editorial. What will you write about, and for whom?

Finding Your Niche

Successful Substack publications tend to be specific rather than broad. “Business news” is too general. “Weekly analysis of SaaS company earnings for product managers” is a niche.

Ask yourself:

What do you know deeply? Your professional expertise, personal obsessions, or unique perspective
What questions do people ask you? The topics friends, colleagues, or online communities come to you for
What’s underserved? Where the existing content is too broad, too shallow, or too infrequent

Defining Your Reader

Write for a specific person, not a demographic. Create a mental model of your ideal reader:

What’s their role or situation?
What problem does your newsletter solve for them?
How often do they want to hear from you?
What tone do they expect (formal, casual, data-driven, narrative)?

Step 2: Create Your Publication

Signing Up

Go to substack.com and click “Start writing.” You’ll create an account with email, Google, or Apple sign-in.

Publication Name

Choose a name that’s:

Descriptive enough that new readers understand the topic at a glance
Memorable so subscribers can recall and recommend it
Not too long — it appears in email subject lines and browser tabs

You can change the name later, but early subscribers will associate your publication with whatever you start with.

Handle (URL)

Your Substack URL will be yourhandle.substack.com. Choose something short, clean, and related to your publication name. If you plan to use a custom domain later, this matters less — but it’s still your URL for the early stages.

Publication Description

Write a clear, concise description (1-2 sentences) that answers: “What will I learn by subscribing?” This appears on your publication page and in search results.

Logo and Branding

Upload a publication logo (square, at least 256x256 pixels). This appears in emails, on your publication page, and in Substack’s recommendation system. A clean, recognizable logo makes your publication feel professional from day one.

Step 3: Configure Essential Settings

Homepage Layout

Substack offers several homepage layouts. For most new publications, the default (featuring your latest post prominently) works well. You can customize this as your archive grows.

Email Settings

Configure your “From” name — this is what subscribers see in their inbox. Most writers use their personal name or publication name. Some use a combination: “Matt from The Weekly Update.”

Categories and Topics

Select relevant categories for your publication. This helps Substack’s recommendation algorithm surface your work to potentially interested readers.

Custom Domain (Optional)

You can connect a custom domain (like newsletter.yourdomain.com or yourdomain.com) from the start. This is recommended if you plan to build a brand beyond Substack. A custom domain improves SEO and gives you a professional URL to promote.

Step 4: Plan Your First Posts

Don’t publish immediately. Plan your first 3-5 posts before going live.

The Welcome Post

Your first post should:

Introduce yourself and your credentials
Explain what the newsletter covers
Set expectations: frequency, format, tone
Give readers a reason to subscribe (what value will they get?)
Include a clear call to action: “Subscribe to get [value proposition] every [frequency]“

The Showcase Post

Your second or third post should demonstrate the publication’s value. Write the best example of a typical issue:

If you do analysis, publish a compelling analysis piece
If you curate, publish an exceptionally well-curated issue
If you teach, publish a genuinely useful how-to

This post serves as proof that subscribing is worth it. When you promote your newsletter, this is the post you’ll link to.

Building a Pipeline

Having 3-5 posts planned (even as outlines) ensures you won’t scramble for ideas after the initial excitement fades. A content pipeline is the foundation of consistency.

Step 5: Set Up Your Writing Workflow

Writing Inside vs. Outside Substack

Substack’s editor is functional but basic. Many writers prefer to draft outside Substack and paste in the final version.

Popular writing tools:

Markdown editors (VS Code, Obsidian, iA Writer): fast, distraction-free, portable
Google Docs: easy collaboration and commenting
Notion: combines drafting with content planning
Dedicated writing apps: Ulysses, Scrivener, Bear

If you draft in markdown, you’ll need to convert to rich text before pasting into Substack. Tools like DownStack handle this conversion automatically, including turning markdown tables into hosted images that display properly in Substack.

Creating Templates

Develop templates for your recurring post formats. If you publish a weekly roundup, create a markdown template with your standard sections. This reduces friction and maintains consistency.

Step 6: Publish and Promote

Publishing Your First Post

When you hit publish, Substack gives you options:

Email + web: sends to subscribers and publishes on your site (the default and usually the right choice)
Web only: publishes on your site without emailing subscribers
Email only: sends to subscribers without a web version (rare use case)

For your first post, use “Email + web” so your initial subscribers get notified and a web version exists for sharing.

Initial Promotion

Your first subscribers will come from your existing network:

Share on social media (Twitter/X, LinkedIn, Facebook)
Email your personal contacts
Post in relevant communities (Reddit, Discord, Slack groups) where self-promotion is allowed
Add your Substack link to your bio on every platform
Cross-promote with other newsletter writers in your space

Recommendations: other Substack writers can recommend your publication to their subscribers
Notes: Substack’s social layer lets you share thoughts and links to your posts
Leaderboard: top publications in each category get additional visibility
Search: Substack’s internal search helps readers find publications on topics they care about

Step 7: Establish Your Cadence

Consistency matters more than frequency. A weekly newsletter that arrives reliably every Tuesday is better than a “daily” newsletter that publishes erratically.

Common frequencies:

Daily: high commitment, best for news-driven or very short-form content
3x per week: heavy cadence, works for timely analysis
Weekly: the most popular and sustainable cadence for most writers
Biweekly: good for in-depth, research-heavy publications
Monthly: minimum viable frequency — any less and subscribers forget you exist

Choose a cadence you can sustain for at least a year. You can always increase frequency; decreasing it after subscribers expect daily content feels like a broken promise.

Step 8: Build Your Subscriber Base

The path from 0 to 100 subscribers is different from 100 to 1,000. Early growth is about direct outreach; later growth is about systems.

0-100 Subscribers

This is pure hustle. Share every post personally. Ask friends to subscribe and forward. Reply to every comment. DM people who engage with your social media posts about the newsletter’s topic.

100-1,000 Subscribers

Systems kick in. Cross-promotions with similar-sized newsletters, guest posts, SEO from your web archive, and Substack recommendations begin generating organic growth.

Free vs. Paid from the Start

A common question: should you offer paid subscriptions immediately?

Start free if you’re building an audience from scratch. Proving value before asking for money builds trust and makes the eventual paid launch more successful.

Start with a paid tier if you have an existing audience (from a blog, social media, or previous newsletter) that already knows your work.
