Audience Growth on Substack and Twitter
Understanding Substack and Twitter
Your Direct Line
Substack is a platform that puts writers directly in touch with their readers. At its core, it’s a tool for creating and sending email newsletters. Instead of relying on social media algorithms to show your work to followers, Substack sends your writing straight to your subscribers' inboxes.
Substack, on the other hand, was built for writers.
This direct connection is the key. You build and own your email list, creating a loyal audience that has explicitly asked to hear from you. The platform provides everything you need to get started: a simple editor for writing, tools to manage free and paid subscriptions, and community features like comments and discussion threads. The focus is on long-form, thoughtful content that builds a lasting relationship with readers.
The Public Square
Twitter, now known as X, is the world's bustling public square. It's a fast-paced environment where conversations happen in real-time, driven by short bursts of text, images, and videos. Unlike the direct channel of a newsletter, Twitter is all about discovery and broad reach.
Its main function is microblogging. You share ideas, news, and updates in short posts. Threads allow for slightly longer, sequential thoughts. The platform is designed for quick interaction and public discourse. Your posts are visible to your followers and can be discovered by anyone through hashtags, retweets, and the platform's algorithm. It's a place to find new audiences, participate in wider conversations, and build a public-facing brand.
Twitter’s conversational tone and short form content style lends itself well to personal branding, and you will even see corporate brands take a more personal approach with their Twitter content, with some brands speaking in the first person, regularly posting humorous Tweets, and engaging in back-and-forth exchanges in Tweet comments.
Two Platforms, Two Roles
Think of Twitter as the lively party where you meet new people and start interesting conversations. Substack is the quiet coffee shop where you invite those people for a deeper, more personal discussion. They aren't competing platforms; they serve different but complementary purposes for a creator.
| Feature | Substack | Twitter (X) |
|---|---|---|
| Content Format | Long-form articles, essays | Short posts, threads, media |
| Pace | Slower, more thoughtful | Fast, real-time |
| Audience | Direct, owned (email list) | Broad, follower-based |
| Primary Goal | Build deep community | Increase discovery and reach |
You can use Twitter's broad reach to attract people who are interested in your ideas, then encourage them to subscribe to your Substack for more in-depth content. This creates a funnel, moving casual followers toward becoming a dedicated audience.
Engagement Is Everything
On both platforms, success isn't just about posting content. It's about engaging with the people who read it. You're not just a broadcaster; you're a community builder.
On Twitter, engagement means replying to comments, retweeting others, and participating in conversations. This activity signals to the algorithm that your account is valuable, increasing your visibility and helping new people find you.
On Substack, engagement happens in the comments section of your posts and through reader replies to your emails. This interaction builds loyalty. It shows your subscribers that you're listening and value their input, which turns a simple email list into a thriving community.
When you create a two-way street of communication, you’re not just building a following – you’re cultivating a community that’s more likely to support your monetization efforts.
