Substack Notes Strategy 2026: How to Grow on Substack Now

A good Substack Notes strategy in 2026 is 2-3 Notes a day, each built around one idea, with links kept out, plus a daily habit of commenting on and restacking writers whose readers overlap with yours. Substack's growth now happens inside its own app, and Notes is where writers report most new subscribers come from. Pair the Notes with one 1,500-2,000-word essay a week on a fixed day, and give it six months.

The short version

• Substack's last official figure (February 2024) says Recommendations plus the app drive 50% of all new subscriptions. Writers report Notes as the biggest single source inside that.
• Multi-line Notes beat single-line ones, and a Substack link in a Note cut average restacks from 2.11 to 1.29. Name your essay instead of linking it.
• Post 2-3 Notes a day. Keep self-promotion to about a fifth of them.
• Comment on bigger writers for discovery. Restack-with-note for peers you want to be paired with.
• Before promoting anything, name the publication after yourself, keep it free, publish three posts and rewrite the welcome email.
• Publish one essay a week on the same day. Give it six months before you judge it.

How does Substack growth work in 2026?

Substack has published a run of figures on how much of a writer's growth comes from its own network. Each one is bigger than the last.

February 2024 is the most recent official breakdown I could find. Numbers you'll see quoted for 2025-26, like "32 million new subscribers from within the app," don't trace back to a Substack source, so I'd treat them as rumor.

Inside the app, Notes is the channel writers keep crediting. One writer attributes 30-40% of her subscribers to Notes, and the same post claims Notes drove 60%+ of growth from 11 to 5,800 subscribers. That post also sells a $97 course. A writer under 100 subscribers reports single Notes bringing 15-20+ subscribers. All of this is self-reported. Substack's own analytics also lump network sources into one bucket, so nobody can fully verify the split.

What the feed optimizes for comes secondhand. Mike Cohen, Substack's head of machine learning, is quoted by people who attended a Substack Notes event as saying "we're optimizing for sign-ups and subscriptions". No transcript exists. The mechanism writers describe is audience overlap. When you restack or reply to another writer's Note, you signal that your readers overlap, so each of you may be shown to the other's audience.

My take is that every growth tactic on Substack is a way of getting paired with the right writers. Keep that in mind and the rest of this guide follows from it.

How should you set up a Substack before you grow it?

Setup takes an afternoon, and a few choices are hard to undo. Your profile (which posts Notes and comments) is separate from your publication. You can rename a publication later, but writers report the rename can change the URL and break links you've shared.

The free-first advice comes from Substack's own "first 100 subscribers" guide, which says "the focus is on helping new readers find your writing". The About page fails most often by being "vague, inspirational, or overly personal". Buffer's creator guide says writers rank Recommendations as one of the most effective growth strategies they use.

No data shows that personal-name publications grow faster than topic names. I'd still use your name if the goal is a personal brand, because the person posting Notes and the publication collecting subscribers should be the same identity.

What should you post on Substack Notes?

Write one idea per Note. Use short lines with white space, and open with a blunt, contrarian or question hook. Add a photo now and then, and lean on proof: screenshots, results, a before-and-after. That's the craft advice from PubStack Success and Write Build Scale, and packing several ideas into one Note is the mistake they flag.

The format data points the same way. A dataset of about 20,000 Notes found multi-line Notes averaged 11% more reactions and 28% more restacks than single-line ones. Links hurt. Including a Substack link cut average restacks from 2.11 to 1.29.

So name your essay in the Note and let curious readers find it through your profile. Don't paste the headline and the URL. One writer calls that pattern "broadcasting rather than conversation". Keep promotion to about one Note in five, in line with the 80/20 value-to-soft-CTA split Write Build Scale suggests.

Personal beats useful more often than you'd expect. One writer found her most helpful how-to Notes often did worse than relatable personal ones, and another puts it as "people don't subscribe to tips. They subscribe to people." My rule is to tell the story and then land the lesson.

Two habits get more out of each Note. Repost a strong Note about a month later, since most of the people who see it the second time are new. And use Notes as your test kitchen. Kevin Indig, profiled by Buffer, says "a Note takes only a few minutes, while a fully researched Memo takes an entire week, so testing ideas in Notes first is worth it." The Notes that get replies become next month's essays.

How many Substack Notes should you post a day?

Two to three. Wes Pearce tracked six months of his own Notes on a 10,000+ subscriber publication and landed on 2-3 a day as the sweet spot. Another writer calls two a day the minimum that moves the needle.

Some guides push 3-5 a day. Older advice said five or more, and at least one writer found that unsustainable. The advice has drifted down for a reason. If you have a full-time job, start at two and add a third once the habit holds. There's more on fitting this around work in personal branding with a full-time job.

How do you engage on Substack without being spammy?

Engagement on Substack is relationship work with other writers. A compact routine is the "10-5-1 rule": like 10 Notes, leave 5 meaningful comments and send 1 DM per session. The same source says coordinated engagement groups don't work on Substack the way they might elsewhere.

Where you engage depends on what you want.

Your comment appears only under the host's content, in front of their audience instead of yours. So when your network is small, comment on more popular writers' Notes. For peers, the same guide is blunt: "If you are trying to grow, restack with a note." The comment-writing skills carry over from LinkedIn, and how to comment on LinkedIn covers what a substantive comment looks like.

Two rules keep you out of trouble. Never drop a link to your own work in someone else's comments, because your profile link travels with every comment anyway. And ask for a recommendation only from writers already engaging with your work. Cold swap offers to strangers "lead to low-quality matches and ignored emails."

Guest posts are the other big lever, and they matter most early. Lenny Rachitsky's guest post on an audience-matched newsletter added about 500 subscribers on his way to 1,000. To get a yes, pitch publications that already run guest posts. As one writer warns, "most failed Substacks are solo operations."

How long should a Substack post be?

Aim for 1,500-2,000 words. A self-published analysis of about 3.85M posts put the engagement sweet spot at 500-2,000 words, and a machine-learning pass over 39,000 articles landed on roughly 1,500-2,000. Longer titles did a bit better too. Across 94,000 posts, 13-17-word titles averaged 26.8 reactions against 21.1 for titles of one to five words.

Read these numbers loosely. Every study here is self-published by Substack writers, correlational and poorly controlled for publication size. The 39,000-article author warns of a "celebrity effect," where short posts from huge newsletters skew the results. Treat them as a starting range and adjust once your own data comes in.

Can you schedule Substack Notes?

Yes, two ways. Substack shipped native Notes scheduling on March 23, 2026 on web, iOS and Android. It's free and lets you schedule about three months out. It handles one Note at a time, though, with no queue, calendar or bulk scheduling.

Buffer added Substack Notes on September 23, 2026, on every plan including Free. You can batch Notes, cross-post them to X, LinkedIn, Threads and Bluesky, and see free and paid subscribers gained per Note. Buffer can't read or post replies, because Substack doesn't allow it, and it doesn't do long-form posts.

That split defines the workflow. Buffer's own team ran a month-long experiment and treated scheduling as "the consistency layer". They batch-wrote most of the week in one session and left one or two slots open for reacting to the feed. Replies and restacks, where the pairing happens, stay manual. Budget daily time for them.

How often should you publish on Substack?

Once a week, on a fixed day, for at least six months. Wes Pearce's lessons from 7,000+ subscribers include staying consistent for six months, and Buffer's guide warns that "newsletter growth, in general, tends to be slow and steady." Chenell Basilio grew to 20,000+ subscribers in eight months publishing something new every week.

Best-day advice conflicts. Substack's data team said informally that open rates run slightly higher on weekends, with Sunday ahead of Saturday, and that it depends on the niche (some finance publications do well on Mondays). That contradicts the generic Tuesday-to-Thursday advice. My rule is to pick one slot, hold it for four or five issues, then try another and compare.

Substack is one part of a wider system. If you're also posting on LinkedIn, X or Instagram, the four-platform personal branding playbook shows how one weekly essay feeds all of them.

FAQ

Do Substack Notes help you get subscribers?

Writers consistently report that they do, with individual writers crediting 30-60% of new subscribers to Notes. Those figures are self-reported, and Substack's analytics don't separate network sources cleanly. Substack's official February 2024 figure puts its whole in-app network at 50% of new subscriptions.

Should you put links in Substack Notes?

Mostly no. One dataset found a Substack link cut average restacks from 2.11 to 1.29. Name the essay in the Note and keep link-style promotion to about one Note in five.

How do you get recommended on Substack?

Engage for weeks with writers of similar or slightly larger size before you ask for anything. Ask only writers who already comment on or restack your work, since cold swap requests get ignored. Turn on Recommendations yourself and recommend writers you read.

Should a new Substack be free or paid?

Start free. Substack's own first-100-subscribers guide says to keep all content free at the start so new readers can find you, and a free list makes a later switch to paid easier.
