Free Guide to Starting Your Substack Newsletter

Understanding What Substack Is and How It Works

Substack is a platform that lets writers send newsletters directly to readers' email inboxes. The company was founded in 2017 and has grown to host over 3 million publications. Unlike social media platforms where algorithms decide what people see, Substack puts the writer's content directly into subscriber inboxes. This means your readers will actually receive what you write, rather than having it filtered or hidden by a platform.

The platform works on a simple model: you create a newsletter, people subscribe to it (usually through their email), and you send out written content on whatever schedule you choose. Substack handles all the technical parts like managing email lists, sending newsletters to thousands of people at once, and handling unsubscribe requests. You focus on writing; Substack handles the delivery infrastructure.

Substack offers both free and paid subscription options for your readers. If you choose to offer paid subscriptions, Substack takes a 10% cut of what you earn, and payment processing takes another 3%. This means if someone pays $10 per month for your newsletter, you'd receive $6.30 (Substack keeps $1 and payment processing takes about $0.70). For free newsletters, Substack makes no money from you—they're building their business on the hope that some writers will eventually use paid subscriptions.

The platform has become popular with journalists, scientists, authors, academics, and business professionals who want to build direct relationships with their audiences. According to Substack's own data, there are over 500,000 paid newsletters on the platform, though the vast majority of newsletters are free. Writers have reported earning anywhere from a few dollars monthly to over $50,000 per month, though these represent outliers rather than typical outcomes.

Takeaway: Substack is a tool for sending regular written content to subscribers via email. It handles technical logistics while you focus on writing content. The platform itself is free to join, and you only pay fees if you decide to offer paid subscriptions.

Setting Up Your Account and Creating Your First Newsletter

Creating a Substack account takes about five minutes. Visit substack.com and click the sign-up button. You'll need an email address and a password. Substack will ask for your name and will create a unique URL for your newsletter—for example, yourname.substack.com. You can change this later if needed, though keeping it simple and professional is generally recommended.

After creating your account, you'll reach your dashboard. This is your control center where you'll write posts, manage subscribers, and adjust settings. Substack calls each piece of writing a "post," and you can make posts public (visible on your newsletter's public page) or private (sent only to subscribers). Many writers use the public home page as a kind of archive where readers can browse past issues.

Before you publish your first post, take time to fill out your newsletter's profile information. Add a description that explains what your newsletter is about—keep this to a few sentences that someone unfamiliar with your work would understand. Add a profile photo of yourself; studies on email newsletters show that including a writer's photo increases engagement. You can also add a cover image and write a longer bio explaining your background and why you started the newsletter.

Creating your first post is straightforward. Click "New post" and you'll see a writing editor. Substack's editor is fairly basic—it includes formatting options like bold, italics, headings, and the ability to embed links. You can paste in images and even embed videos from YouTube or other sources. Write your content, add a subject line (this is what appears in email inboxes), and review how it looks. When you're ready, you can preview how it will appear in emails before publishing.

One important decision: will your newsletter be free, paid, or both? You can change this later, but most writers start with free. A free newsletter builds audience and tests whether you can write consistently. If you later add paid options, your existing free subscribers won't be charged—you'd create a separate paid tier for new subscribers.

Takeaway: Set up takes minutes and requires just basic information. Before publishing, complete your profile with a description, photo, and bio so visitors understand who you are and what the newsletter covers.

Building Your Audience and Gaining Subscribers

Substack doesn't provide built-in traffic—you need to tell people about your newsletter. This is the most challenging part for most new writers. The good news is that newsletters have unusually high engagement rates compared to social media. According to industry data, email newsletters have average open rates of 40-50%, compared to social media posts where 1-3% of your followers typically see each post. This means once someone subscribes, they're likely to read what you write.

The most direct way to gain subscribers is to promote your newsletter on platforms where you already have an audience. If you have Twitter, LinkedIn, Instagram, or a personal blog, let people know about your newsletter. You might write: "I'm starting a newsletter about [topic]. Subscribe at [your link]." Many successful Substack writers have built their audiences through existing platforms—a Twitter account with followers, a popular blog, or even a podcast following.

Another effective method is creating a landing page or website that directs people to subscribe. This can be as simple as a single webpage created on free services like Carrd or Notion. You could write a few paragraphs explaining what your newsletter covers and who should subscribe, then include a subscribe button linking to your Substack. Some writers create multiple landing pages targeting different audiences or topics.

Word-of-mouth and cross-promotion work well for newsletter growth. When your readers enjoy what you write, they often share your newsletter with others. You can encourage this by writing great content and occasionally asking readers to forward posts to people who might find it interesting. Many writers also discover each other through Substack's recommendation features and collaborative networks. Substack displays "popular newsletters" and allows writers to recommend other newsletters to their subscribers.

Guest posts and interviews can bring new audiences. If you interview someone notable in your field or appear on someone else's newsletter as a guest writer, their audience gets exposure to your work. Similarly, some writers collaborate on joint editions where they write about the same topic from different perspectives.

Some writers use paid advertising on platforms like Twitter, Facebook, or Google to promote their newsletters, though this requires budget and isn't necessary when starting out. Many successful Substack writers built their audiences without spending money on ads.

Takeaway: Growth comes from promoting your newsletter through existing audiences, collaborations, and creating excellent content that readers want to share. Build an audience gradually rather than expecting immediate subscribers.

Creating Content That Keeps Readers Engaged

The most successful newsletters have a clear purpose and consistent voice. Before you write regularly, define what your newsletter is actually about. Is it weekly commentary on industry news? A deep dive into one topic? Personal essays? Curated links to articles? Data analysis? Educational content? Readers subscribe because they know what to expect. A newsletter that jumps randomly between different topics and purposes tends to lose subscribers.

Consistency matters more than frequency. It's better to publish one thoughtful post every two weeks and maintain that schedule than to send three posts one week and then disappear for a month. Readers appreciate predictability. When you establish a schedule—such as "every Tuesday morning" or "twice weekly"—stick to it. Many writers publish once weekly, though some go twice weekly, and others publish once or twice monthly. Choose a frequency you can maintain indefinitely.

Great newsletter writing is usually conversational rather than formal. Readers open email expecting to connect with a person, not read a press release. This means using "I" and "you," asking questions, sharing personal observations, and writing how you actually speak. This doesn't mean being unprofessional—it means being warm and approachable. Compare these two openings: "This week's market analysis indicates a 2.3% fluctuation in equities" versus "This week stocks did something weird, and I'm honestly confused too. Let me walk you through what happened." The second feels like a real person explaining something to a friend.

Longer writing performs better in email newsletters than short posts. While social media rewards brevity, email newsletters do better with 800-2,000 words. This length gives you space to develop ideas fully, which is actually what email subscribers prefer compared to short bursts of text. They've already committed to reading your email; they want substantial content.

Including clear structure helps readers follow your thinking. Use headings to break
