You might see someone text, “I just posted it on Substack,” “Read my Substack,” or “I found this on Substack,” and wonder if “Substack” is some kind of texting slang.
It isn’t.
Substack is the name of an online publishing platform where writers, journalists, creators, podcasters, and other people publish content for subscribers. That content can include newsletters, articles, podcasts, videos, and discussions.
So when someone uses “Substack” in a text message, they’re usually talking about the platform itself or a particular publication created on it.
Quick Answer
Substack in text usually refers to the Substack publishing platform or someone’s publication/newsletter on Substack. It is not a traditional texting abbreviation or slang term. For example, “Check out my Substack” usually means “Check out my articles or newsletter on Substack.”
What Does Substack Mean in Text?
When someone says “Substack” in a text, the meaning depends slightly on how they use it.
Most commonly, they mean one of two things:
- Substack as a platform: The website/app where creators publish content.
- A Substack publication: A specific writer’s newsletter, blog, or collection of posts hosted on the platform.
For example:
Friend: “Have you read Maya’s Substack?”
You: “No, send it to me.”
Here, “Maya’s Substack” probably means Maya’s publication or newsletter on Substack, not the entire platform.
Substack describes itself as a publishing platform for writers, podcasters, and video creators. It combines publishing, email newsletters, subscriptions, community features, and audience discovery in one place.
Is Substack a Texting Abbreviation?
No.
Unlike LOL, BRB, IDK, BTW, or WYD, Substack isn’t an abbreviation people created for faster texting.
It is a proper name/brand. If someone types “Substack” in a conversation, they’re generally referring to the platform or something published there.
That’s an important distinction because searching for a “hidden slang meaning” can make the word seem more complicated than it really is.
Why Do People Use “Substack” in Conversations?
People mention Substack because it has become a place where individual creators can publish directly to an audience.
A writer might publish an article, send it to subscribers by email, and also make it available through their publication page or the Substack app. Subscriptions can be free or paid.
This creates some common conversational phrases:
- “I have a Substack.” → I run a publication/newsletter on Substack.
- “Read my Substack.” → Read what I’ve published there.
- “I’m starting a Substack.” → I’m starting a publication or newsletter on the platform.
- “She writes on Substack.” → She publishes her work through Substack.
- “I found it on Substack.” → The content originally appeared on a Substack publication.
So the meaning often becomes clear from the verb around the word.
“Subscribe to my Substack” means something different from “I downloaded Substack,” but both are connected to the same platform.
Where You’ll See “Substack” Online
Text Messages
Texting is one of the most common places where you may encounter the word indirectly.
Someone might send:
“I wrote about this in my Substack. I’ll send you the link.”
The person isn’t using “Substack” as slang. They’re telling you where their writing is published.
Creators sometimes mention their Substack in an Instagram bio, Story, caption, or DM.
For example:
“Full article is on my Substack.”
That generally means the longer version of the content is available through their Substack publication.
TikTok
A TikTok creator may say:
“I explained the whole story in my Substack.”
In this situation, Substack means the creator’s longer-form publication, where they can go beyond the shorter social-media format.
Snapchat
You may occasionally see someone share a Substack link through Snapchat or mention that they have a newsletter there.
Again, it is a platform reference—not Snapchat slang.
Discord and Online Communities
Someone discussing writing, journalism, technology, culture, finance, or another specialized topic might recommend a Substack publication.
For example:
“There’s a really good Substack about AI research.”
Here, the speaker is referring to a publication/newsletter focused on AI research.
Gaming communities can also share Substack links, but “Substack” itself isn’t a standard gaming abbreviation.
Real-Life Examples of “Substack” in Text
Example 1: “Check out my Substack.”
Conversation:
Alex: “I finally published my first essay.”
Sam: “Where?”
Alex: “On my Substack. I’ll send you the link.”
Meaning: Alex has published the essay through their Substack publication.
Tone: Casual and informative.
Example 2: “I found this on Substack.”
Conversation:
Mia: “Where did you find that analysis?”
Chris: “I found it on Substack last night.”
Meaning: Chris found the article or post on the Substack platform.
Tone: Completely neutral.
Example 3: “You should subscribe to her Substack.”
Conversation:
Jordan: “You like her writing?”
Taylor: “Yeah. You should subscribe to her Substack.”
Meaning: Taylor recommends subscribing to that creator’s publication.
Substack supports free subscriptions as well as paid subscription plans, depending on how the creator has set up their publication.
Tone: A recommendation.
Example 4: “I’m launching a Substack.”
Conversation:
Nina: “What are you working on?”
Leo: “I’m launching a Substack about movies.”
Meaning: Leo is creating a publication on Substack where they plan to publish content about movies.
Tone: Casual but potentially professional or business-related.
Context Matters: “Substack” Can Mean the Platform or a Publication
This is probably the most useful distinction to remember.
If someone says:
“Substack has a mobile app.”
They mean the platform/company and its services.
But if they say:
“Her Substack is really good.”
They probably mean her individual publication or newsletter.
And if they say:
“Subscribe to my Substack.”
They’re almost certainly referring to their publication, rather than asking you to subscribe to the entire Substack platform.
Substack’s own reader guidance also distinguishes subscribing to a publication from simply following someone. A subscription can deliver that publication’s posts by email and/or through the app, while following is a lighter way to see activity in the Substack network.
Common Mistakes and Misunderstandings
“Substack” Does Not Mean “Subscribe”
The words look related because Substack has subscriptions, but Substack is the name of the platform.
Someone saying:
“Check my Substack.”
isn’t simply saying:
“Check my subscription.”
They’re referring to their publication.
It Isn’t Gen Z Slang
Substack can appear in conversations among younger internet users, but that doesn’t make it slang.
It’s more accurate to call it a platform or brand name.
It Doesn’t Automatically Mean Paid Content
Another common misunderstanding is assuming that every Substack publication costs money.
That’s not true. Creators can offer free content, paid content, or a combination of both. Substack’s current support information says creators can offer free, monthly, annual, and other subscription options.
“My Substack” Doesn’t Mean They Own Substack
If someone says:
“I’m posting on my Substack.”
they usually mean their own publication hosted on Substack, not that they own the company.
Should You Use “Substack” in a Text?
Yes, if you’re talking about the platform or a publication hosted there.
It’s perfectly natural in casual conversation:
“I’ll send you my Substack.”
“Did you read her latest Substack?”
“I found a great writer on Substack.”
You don’t need to spell it out or explain what it means every time.
However, if you’re messaging someone who may not know the platform, adding a little context can help:
“I published a newsletter on Substack—I’ll send you the link.”
That makes the meaning obvious.
For formal business communication, “Substack” is still fine when the platform is relevant. Just avoid treating it like an abbreviation or writing it as though it has a hidden texting meaning.
Is Substack the Same as a Newsletter?
Not exactly.
A newsletter is a type of content or publication. Substack is a platform used to publish and distribute that content, although the platform now supports more than newsletters, including podcasts, video, live content, and community features.
Think of it this way:
Newsletter = the content/publication
Substack = the platform where it can be published
That’s why someone can say, “I have a Substack,” even if their publication includes much more than traditional email newsletters.
