The results shocked me.

Hi Sutoscientists,

I need to tell you something that’s been on my mind and would’ve saved me a lot of time, money, and… emotional attachment to little orange “like” numbers.

For the last six months, I treated Substack Notes like it was the growth lever. (And if you don’t know what Substack Notes is, it’s the X/Threads/Bluesky/social media platform side of Substack all of us Substackers are spending too much time scrolling on.)

It’s an important side of Substack to grow on, because there’s a little “subscribe” button by every post that helps new readers discover you and your publication.

So, I posted constantly on Notes. I tracked everything. I tried to “crack the code.”

I even hired someone for three months whose entire job was basically: figure out how to grow on Substack Notes.

And here’s the weird part:

It worked.

Like… objectively, it worked.

But it didn’t work the way my brain wanted it to work.

Because in my head, there was this simple math:

“If we can get 1,000 likes, surely at least 10% of those people will subscribe.”

That’s what feels true when you’re staring at a post that’s popping off.

So I want to show you the exact Notes that did the best for us — the ones that would be a dream for most people — and what they actually produced in terms of subs, paid, and revenue.

And then I want to give you the real takeaway:

Notes can be amazing, but it’s very easy to spend a ton of time there… and accidentally optimize for the wrong outcome.

❗️So here are the types of posts we experimented with — and the format that actually did numbers when it came to paid subscribers:

Substack Note #1 (Meme Format): “The limit does not exist”

This one is the perfect example of what Notes does really well.

It got:

  • 15.8K likes

  • 290 replies

  • 2.5K restacks

In other words: it moved.

This is the kind of post that makes you sit up straighter and go, “Ohhh okay, we found it. We found the thing.”

And here’s what it taught me:

Memes are incredible at getting you eyes.

Memes are also incredible at giving you a tiny hit of “yes, I’m doing it right.”

But memes are not designed to create the mental moment that leads to paid conversion, which is:

“This is for me. This solves my problem. I trust this person.”

A meme creates: “lol same.”

Paid conversion requires: “wait… I need that.”

That’s not a judgment. It’s just physics.

And now for my paid subscribers…

I’m going to show you the real stats behind this.

Not the public stuff like likes and shares.

I mean the numbers only I can see:

  • exactly how many subscribers this brought in (free + paid)

  • how much revenue it actually generated

  • and what the conversion looked like when the post was “going viral”

Because this is the part nobody talks about: sometimes a Note can look like a dream… and still be the wrong lever if you’re trying to grow paid.
