Notes or Posts: Which One Actually Grows Your Substack?

Everyone says the same thing. Post more notes. Be consistent with notes. Notes are the key.

Then they move on without explaining why, which leaves you guessing whether to dash off a quick note or finish the long post you have been putting off.

The honest answer is that they do different jobs, and if you only do one you are working against yourself.

One thing to be clear about first: I do not have hard data comparing note growth to post growth across thousands of publications. Nobody has handed me a controlled experiment. What I have is a read of the mechanics, how each format actually moves through Substack. That is what this is based on.

What a post actually does

A post goes to your inbox list. People who already subscribed get it delivered. They already said yes to you.

So a post deepens a relationship that exists. It is the reason someone stays, the thing that makes the subscription feel worth something.

If your posts are good, people keep showing up. If your posts stop, people forget you exist.

What a post almost never does is travel. It lands in an inbox and stays there. It serves the people you already have, which is valuable, but it does not go and find new ones.

What a note actually does

A note goes into a feed, and that feed is not just your subscribers. It is shared space. People who have never heard of you can scroll past and stop.

And a note can be restacked. When someone restacks yours, it drops into their audience's feed. Strangers see your name. Some click. Some subscribe.

Notes are the top of the funnel. Posts are what makes following you worth something.

You need both. The only question is whether you are treating them that way.

The two mistakes

Only writing posts. You have a solid archive and a loyal small list, and nothing reaches outside it. New people are not finding you because nothing you write ever appears in front of them. Growth slows, and you wonder whether Substack works for you. The problem is structural: you are only talking to the room you already filled.

Only writing notes. You pick up followers and the numbers move a little. But followers who never get a real post have no reason to become readers. They followed a quick thought and forgot you by Tuesday. Notes without posts are a restaurant with a great sign and no food inside.

Promotion is not a note

The bigger mistake is how most people use notes when they do write them.

"New post out today, link below." That is not a note, that is an ad. It does not get restacked, it does not make anyone stop scrolling, and it signals to humans and the algorithm alike that you are here to sell.

A note that works is writing on its own. A short take. Something you noticed. A question you are genuinely chewing on. Something read to the end because it was worth reading, not because the reader is already a fan.

Whatever you write about, the principle holds. Your readers came for something specific, and a note that hands them one piece of it stands alone. A cook can post the one adjustment that fixed a recipe. A historian can post the detail that changed how they read an event. A developer can post the thing that broke and why.

None of those need a post behind them to justify existing. And if one resonates, someone restacks it, and a room full of people who care about the same things sees your name for the first time.

Notes take time, and that is fair

Here is the objection I hear most, and it is a good one.

Notes are not free. A good one is not just dashed off. You still have to think, write something coherent, and make it worth reading. That is real work on top of your posts, and if you are already writing long every week, a daily note habit can feel like a second job.

I am not going to wave that away.

The answer is not to write worse notes. It is to batch them. Sit down once a week and think about what you have been working on, what caught your attention, what confused you, what clicked. Write five or six short notes at once. Spread them across the week.

Now the discovery side keeps running on the days you are deep in something else.

That is what StackBuddy is built for: drafting and scheduling a week of notes in one sitting, in your voice rather than a template, and showing you which ones got traction so you write more of what works.

So when someone tells you to just post more notes, you now know the actual reason. Notes put you in front of strangers. Posts give those strangers a reason to stay. Neither alone gets you where you want to go.
