Every platform you write on is rented ground. Medium can change the algorithm. Substack can change the rules. Twitter can lock your account. I've been writing online for almost twenty years and the single most important thing I've learned is this: the only audience you truly own is your email list. If you're wondering how to build an email list as a writer, you're asking the right question at the right time.

I spent years building followings on platforms before I took email seriously. That was a mistake. Here's everything I know about doing it right — from zero to a list that actually matters.

Why your email list matters more than followers

Let me put this in numbers. A social media post reaches five to ten percent of your followers on a good day. An email reaches eighty-five to ninety-five percent of your subscribers. That's not a slight difference — it's a different universe.

Followers are a vanity metric. They feel good. They don't convert. When I want to launch a product on my shop, I don't post on social media and hope. I send an email. The difference in response is not close.

There's also the survivability factor. Platforms die. Algorithms shift. Ad models change overnight. Your email list survives all of it. You can export it, move it, take it anywhere. Try doing that with your Medium followers or your Twitter audience.

If you care about writing as a long-term practice — and especially if you want to earn from it — learning how to build an email list is not optional. It's the foundation everything else sits on.

Start with Substack — it's free, it's a blog AND a newsletter

If you're starting from zero, Substack is the fastest way to get moving. It's free. It gives you a blog and a newsletter in one tool. Every post you publish automatically goes to your subscribers' inboxes. No plugins, no integrations, no technical setup.

I run my Substack alongside my Medium presence and they serve different purposes. Medium is for reach. Substack is for depth and ownership. When someone subscribes to your Substack, that's a real email address you control. That's the beginning of an actual relationship.

Substack also has a built-in recommendation network. When other writers recommend you, their subscribers see your publication. This is free, organic list growth that you don't get with standalone email tools like ConvertKit or MailerLite*. For a writer just figuring out how to build an email list, that network effect is enormously valuable.

I covered the full growth playbook in my guide to growing on Substack — if you're going this route, read that next.

The sign-up that actually converts

Most writers put up a generic "Subscribe to my newsletter" box and wonder why nobody signs up. The problem isn't traffic. It's the offer.

People don't subscribe to newsletters. They subscribe to outcomes. "Get a weekly email about writing" is vague. "Every Thursday, one tactic that helped me grow from 0 to 5,000 subscribers — in under 3 minutes" is specific. Specific converts. Vague doesn't.

A few things that improve sign-up rates immediately:

  • A clear promise. What will the reader get, how often, and why should they care? Answer all three in two sentences or fewer.
  • Social proof. If you have any subscriber count worth mentioning, mention it. "Join 2,400 writers who read this every week" is more compelling than "Subscribe."
  • Low friction. Email field and one button. Nothing else. Every extra field you add kills conversion.
  • A sample. Link to your best past issue. Let people see what they're signing up for. Transparency builds trust.

Your landing page doesn't need to be fancy. It needs to be clear. One promise, one action, one click. If you need a simple landing page fast, Carrd* lets you build a clean one-page site with an email signup in minutes.

Medium as a list-building channel

I've been on Medium for years and it remains one of the best discovery platforms for writers. The key insight is this: Medium is not where you build your list. Medium is where people find you. Your list lives somewhere else.

Here's how the funnel works. You publish on Medium. Medium's algorithm and Google surface your articles to new readers. Those readers who like your work click through to your newsletter. They subscribe. Now they're yours — not Medium's.

Practical tactics that work:

  • Bio link. Your Medium bio should link directly to your newsletter landing page. Not your personal website, not your LinkedIn — your newsletter.
  • End-of-article CTA. Every Medium article should end with a clear call to action pointing to your email list. Keep it one sentence. Make it feel natural, not salesy.
  • SEO-driven articles. Medium articles that rank on Google bring in readers for months or years. Those readers are often the highest-quality subscribers because they found you by searching for something specific. I wrote about this in detail in my Medium SEO guide.

The writers who grow the fastest use Medium as the top of the funnel and email as the bottom. Don't choose between platforms — use each one for what it's best at.

Cross-posting without being annoying

If you're on both Medium and Substack, the question of cross-posting comes up fast. Can you publish the same piece in both places? Yes. Should you? With some care.

The approach that works for me: I write the full piece for my newsletter first. That version is personal, detailed, written for people who already know me. Then I adapt a version for Medium — tighter, more SEO-aware, aimed at a broader audience who might be reading me for the first time.

The Medium version always points back to the newsletter. The newsletter version never points to Medium. The traffic flows one direction: from rented platforms toward owned audience.

What doesn't work: copying and pasting the exact same piece everywhere with the exact same CTA. Readers who follow you on multiple platforms notice. It feels lazy. Adapt the piece to the platform and make each version worth reading on its own.

One more thing: set canonical URLs correctly if you're cross-posting. You don't want Google penalizing you for duplicate content. Medium lets you import posts with a canonical link back to your original. Use it.

Content upgrades and lead magnets that work for writers

A lead magnet is something you give away in exchange for an email address. For writers, the most effective lead magnets are the simplest ones.

What actually works:

  • A curated resource list. "The 15 tools I use to write, edit, and publish — with links and notes." Takes an hour to make. High perceived value.
  • A short guide or checklist. Something specific and immediately useful. My Substack SEO guide started as a lead magnet before I turned it into a full product.
  • A content upgrade. You write an article about, say, writing headlines. At the bottom, you offer "Download my 50-headline swipe file — free for subscribers." The lead magnet matches the content, so it converts well.
  • An email course. "5 days, 5 emails, one writing skill." Auto-delivered via a sequence. This is more work to set up but converts at a high rate and builds immediate engagement.

What doesn't work: generic PDFs that nobody reads, vague promises like "exclusive content," or anything that requires more than thirty seconds to understand. The best lead magnet solves one small problem completely.

The compounding math — what happens at 100, 1,000, 10,000 subscribers

Email lists grow slowly at first and then very quickly. Understanding the math helps you stay patient during the slow part.

At 100 subscribers: You're talking to a room. Every email feels personal. Open rates are high — often fifty percent or more. This is where you figure out what resonates. You're not monetizing yet. You're learning.

Don't underestimate this phase. The writers who quit before 1,000 subscribers almost always quit because they expected faster growth. It doesn't work that way. The first hundred are the hardest.

At 1,000 subscribers: This is the inflection point for most writers. You have enough readers to get meaningful feedback, enough data to see patterns, and enough trust to start offering paid products or a paid tier. If even two percent convert on a $30 product, that's $600 from a single email. Not life-changing, but real.

At 10,000 subscribers: You have a media business. Sponsorships become viable. Product launches generate serious revenue. A single well-crafted email to 10,000 engaged subscribers can outperform months of social media effort. I've written about the revenue side in my newsletter monetization guide.

The key word is "engaged." A list of 10,000 people who never open your emails is worth less than 500 who read every word. Growth matters, but engagement matters more. Clean your list regularly. Remove people who haven't opened in six months. A smaller, engaged list outperforms a bloated one every time.

What I'd do differently if I started over

If I were starting from scratch in 2026, knowing everything I know now about how to build an email list, here's exactly what I'd do:

Day one: set up a Substack*. Free, functional, connected to a network of readers. I'd write my About page carefully and set up a clear welcome email before publishing anything.

Week one: publish three strong pieces. Not "getting started" posts. Real, useful, specific articles that demonstrate what subscribers will get. I'd make these my best work because they'll live on as proof of quality.

Month one: start on Medium. I'd publish adapted versions of my Substack posts and new SEO-driven articles. Every piece would funnel readers toward the newsletter. I'd be strategic about topics — writing about things people actually search for.

Month two: create one lead magnet. Something small, specific, and genuinely useful. A checklist, a template, a short guide. I'd mention it at the end of every relevant article.

Month three onward: consistency. One newsletter per week, one to two Medium articles per week, one Substack Note per day. The specific numbers matter less than the consistency. Showing up regularly builds trust faster than anything else.

The biggest thing I'd do differently? I'd start the list from the very first article. Not after I "had enough content." Not after I "felt ready." From day one. Every day you write without collecting email addresses is a day of lost readers who wanted to hear from you again.

How to build an email list isn't a mystery. It's a practice. Write consistently. Make the offer clear. Use every platform to funnel toward email. Be patient with the math. The writers who do this for a year end up with something no algorithm change can touch.

Your list is your career insurance. It's the one thing that compounds no matter what happens to any individual platform. Start building it today.

A writer is nothing without a reader. If you found this helpful, consider becoming my dear email friend. Nothing would make me happier.
