How to schedule Substack Notes

Substack now schedules single Notes natively. Here's exactly how to use the built-in scheduler, where it stops, and how Eden adds a real queue that publishes with your devices off.

Yes, you can schedule Substack Notes — and since spring 2026 you don't strictly need a tool to do it. Substack added a native Notes scheduler on web, iOS, and Android: open the composer, click the calendar icon, pick a time. That leaves exactly two ways to schedule a note: Substack's built-in scheduler, one note at a time, or a tool like Eden that queues your notes and hands each one to that same built-in scheduler ahead of time, so a whole week publishes on schedule even when every one of your devices is off. Almost no other scheduling tool supports Substack at all, because Substack has no public posting API. This guide walks through both options and where each one stops.

Why you can't schedule Substack Notes in most tools

Every mainstream scheduler publishes through official platform APIs. X, LinkedIn, Threads, Instagram, TikTok, and Facebook all offer one, which is why Buffer, Typefully, Hypefury, and the rest can post to those networks from their servers.

Substack doesn't. There is no public posting API, and Substack blocks automated posting from servers. That single fact explains the strange shape of this market: of the major schedulers we compared in our best social media schedulers guide, Eden is the only one that schedules both Substack Notes and articles. Buffer, Hypefury, Postiz, Metricool, and Later have no Substack support at all, and Typefully added Notes-only scheduling in mid-2026. The Substack-only tool market gets its own ranking in the best Substack schedulers.

So any tool that schedules Notes has to work with Substack rather than around it. That means working through your own signed-in Substack session, and ideally through Substack's own scheduling machinery.

Option 1: Substack's built-in scheduler

Substack rolled out native Notes scheduling in spring 2026 (it headlined the April "New on Substack" product roundup), on web and in the iOS and Android apps. It handles plain text notes well, and it is the most direct way to schedule a single note:

  1. On the web, open the Notes composer and write your note.
  2. Click the calendar icon, pick a date and time, and hit Save, then Schedule. In the mobile app, tap the three dots at the top of the composer and choose Schedule instead.
  3. The note sits with your drafts until its slot, and Substack publishes it automatically.

Its limits are structural. It can't chain a reply thread, it doesn't carry externally attached images the way it handles text, and there is no queue: no default posting times, no reshuffling a week of content, no cross-posting the same idea to X or LinkedIn, and no view of Notes alongside the rest of your content pipeline. If you post a couple of notes a week, it is genuinely all you need. If Notes are a serious channel for you, you will feel the ceiling within a week.

Option 2: schedule Notes through Eden

Eden treats Substack as a first-class network next to X, LinkedIn, Threads, Instagram, TikTok, Facebook, and YouTube. You write a note, pick a slot (or let your default queue times place it), and Eden takes care of the rest. Under the hood it works in two lanes, and being honest about the difference matters:

  • Text notes, which is most notes: scheduled natively on Substack. Ahead of the slot, the first of your devices that comes online quietly hands the note to Substack's own built-in Notes scheduler. Usually that happens seconds after you hit Schedule. From that moment the note shows an "On Substack ✓" badge in your Eden queue, and it will publish at its exact time with your laptop closed and your phone off. You can still edit, reschedule, or cancel it in Eden, and the change syncs to Substack the next time one of your devices is online.
  • Reply threads and image notes: published live at the slot. Substack's scheduler can't chain a reply thread or carry Eden-attached images yet, so these post from your own browser at the scheduled time. Chrome with the Eden extension, or the Eden desktop app, needs to be running within about ten minutes of the slot. If nothing was online, Eden flags the note as a draft with a warning instead of posting it stale hours later.

The same handoff works for long-form Substack articles: Eden hands them to Substack's own post scheduler, and they show up in your publication's Scheduled tab exactly like an article you scheduled by hand.

Set it up in about two minutes

  1. 01

    Install the Eden Chrome extension

    Add Eden from the Chrome Web Store, pin it, click the icon, and choose Connect Eden to link your account.

  2. 02

    Sign in to Substack in that same Chrome

    Open substack.com and make sure you're logged in. Eden acts as your signed-in browser session, so if you're not signed in, nothing can be scheduled.

  3. 03

    Connect Substack in Eden

    In Eden, go to Settings → Scheduling → Connected accounts and click Connect Substack. With the extension installed and Substack signed in, the extension links your account and fills in your handle automatically.

  4. 04

    Optional: connect your phone too

    In the Eden mobile app (iPhone or Android), open schedule settings and tap Substack on this phone → Connect, then sign in. Notes you schedule from your phone are handed to Substack seconds later, no computer involved.

  5. 05

    Schedule your first note

    Write a note, choose Substack, pick a time, and save. When the "On Substack ✓" badge appears in your queue, the note is locked in on Substack's side. You can verify it any time in Substack's own drafts.

What to expect day to day

  • Text notes publish at their slot with devices off. Once you see "On Substack ✓", it is on Substack's scheduler and no longer depends on you.
  • Edits are honest about timing. Changing a handed-off note works from Eden and syncs the next time a device of yours is online. If nothing comes online before the slot, the original version posts, and the queue shows you that state.
  • Reply threads and image notes need a live browser at the slot, and missed ones are flagged as drafts rather than posted late.
  • Scheduling from anywhere is instant. Web, phone, or even the Eden connector in Claude: your devices are woken immediately to do the handoff.
  • Your other networks are unaffected. X, LinkedIn, and the rest still publish from Eden's servers whether or not your computer is on.

Frequently asked questions

Can I schedule Substack Notes without any third-party tool?

Yes. Since spring 2026, Substack's own composer schedules single text notes on web, iOS, and Android: calendar icon, pick a time, Schedule. If you post a couple of notes a week, use it and skip tools entirely. A tool earns its place when you batch — a week of notes in one sitting, default posting slots, reshuffling the queue, threads and image notes, and cross-posting the same idea to X, LinkedIn, or Threads without retyping it.

Can Buffer, Hypefury, or Typefully schedule Substack Notes?

Buffer and Hypefury can't; there is no public posting API for them to build on. Typefully can as of mid-2026: Notes only (text, images, and GIFs), free on all its plans, with no article scheduling. Eden remains the only tool that schedules articles as well as Notes, and the only one that hands both to Substack's own scheduler. We keep the current rankings in the best Substack schedulers.

Is scheduling Notes through a tool against Substack's rules?

Substack blocks automated posting from servers, which is exactly why Eden doesn't do that. Everything runs through your own signed-in session, and text notes are placed on Substack's own built-in scheduler. From Substack's side, a handed-off note looks like one you scheduled yourself, because mechanically that is what it is.

Do scheduled notes perform worse than notes posted live?

We have no evidence they do, and the mechanics suggest they shouldn't: a handed-off text note is published by Substack's own scheduler, the same machinery as a note you schedule by hand inside Substack. If you are optimizing timing, the honest answer is that it matters less than people claim. We analyzed 473,405 notes in our best time to post on Substack study, and the gap between the best and worst posting hour is about three percentage points of breakout odds.

Can I schedule Substack articles too, not just Notes?

Yes. Eden hands long-form articles to Substack's own post scheduler the same way, and they appear in your publication's Scheduled tab on Substack. To edit one after handoff, unschedule it in Eden first, edit, and schedule again.

What happens to a scheduled thread if my computer is asleep?

It doesn't post, and it doesn't post late either. Eden flags it as a draft with a warning so you can reschedule it deliberately. Only text notes, which are the majority of notes, publish with everything off, because those live on Substack's own scheduler.

Scheduling is one half of the Notes game. The other half is knowing what to write, which is where growing on Substack Notes picks up. Eden's free plan gives you 100 saved items and 50 one-time AI credits with no card required, so you can explore the research side first; Substack scheduling is included on paid plans from $29/mo.
