Substack vs Facebook for Writers: Notes, Pages or Groups?

The short answer: Substack Notes is the better place to grow a newsletter, since everyone in the feed already reads on Substack and can subscribe in one tap. Facebook reaches far more people, through your profile, a Page or Groups, and Substack says it rewards full, substantial posts. Use Notes to build the list and Facebook to bring friends and groups along.

Based on Substack Help, On Substack, Facebook Help, Meta, TechCrunch, Nieman Lab and Buffer, checked 1 November 2026.

Most writers already have friends, family and old colleagues on Facebook who would read them. So the question is practical: where should the writing live, and where should the link go? This page compares the three Facebook surfaces with Notes, the path to subscribing on each side, and Substack's own Facebook features.

The row that decides most cases is "Subscribe path." A Note sits one tap from your list.

What Substack Notes does for a writer

Substack Help says Notes are short-form posts where creators share posts, links, images, quotes and comments with their subscribers and "the greater Substack network." Notes are public and can appear on the web, in the Substack app and on your Substack profile. Posting, liking or commenting needs a signed-in Substack account.

Three details matter:

  • Subscribing takes one tap. Substack Help says that if a creator has a publication and you click "subscribe" on their Note, you're subscribed to that publication.
  • The Home feed reaches past your followers. It mixes Notes from people a reader subscribes to or follows, Notes from publications their subscriptions recommend, and restacks.
  • Notes don't hit inboxes. Substack Help says subscribers aren't emailed when you post a Note. They may see it in a Notes roundup digest or a push notification.

A Note can carry up to 6 images or GIFs, or one video of up to five minutes, and you can schedule Notes in the composer. Substack has never published a Notes character limit, and our page on the Substack Notes character limit explains what that means in practice.

Substack has also shared two growth claims. In July 2024, Substack said writers who posted three or more thoughtful Notes in their launch week gained 50% more total subscribers than those who didn't. In October 2024, Substack said the app was the number one source of subscriptions on the platform. Substack doesn't publish a Notes user count. See our guide to growing your Substack with Notes.

What Facebook does for a writer: profile, Page or Group

Facebook gives you three places to post.

Your profile. This is you: your posts, photos and updates, shared with friends or in public. Facebook Help says a creator can turn on pro mode, after which anyone can follow the profile and see its public posts in their Feed.

A Page. Facebook Help describes Pages as places where artists, public figures, businesses, brands and organizations connect with fans. People who like or follow a Page can see its updates in their Feed. A Page suits a writer who wants a public presence kept apart from personal life.

Groups. A Group is a community around a shared interest, public or private. Each Group sets its own rules. Facebook Help says admins can turn on post approval to review every post before it appears. Read a Group's rules before you share a link there.

On size, Meta reported 3.64 billion "Family daily active people" on average for September 2026, up 3% year over year. That figure counts Facebook, Instagram, Messenger and WhatsApp together. Meta doesn't report a Facebook-only user count in its results.

Reach and the path to subscribing

On Notes, a reader can subscribe from the Note itself. On Facebook, the reader has to click your link and sign up on Substack, so every post should earn that click.

Substack's own social guide (On Substack, 29 May 2025) gives two Facebook tips:

  1. Write the full thought. Substack says Facebook and LinkedIn reward substantial content, and advises sharing your complete thoughts, full launch posts and detailed explanations in the post itself.
  2. Tag @followers. On Facebook, Substack suggests tagging @followers in the comments so all your followers get a notification about your post.

The same guide recommends a clear call to action, such as "If you like this, come subscribe."

Tip: write the Facebook post so it stands on its own, with the full idea in the first lines, and put the Substack link last.

Substack's Facebook tools

Substack has four Facebook features of its own:

  • Find friends through Facebook. Substack Help says you can connect your Facebook to your Substack account to follow friends and discover new creators. In the app, you can also sync phone contacts to find people you know.
  • Social preview. In the post editor, Settings lets you edit the title, text and image a shared link shows. Substack Help recommends images of at least 1200 x 630.
  • Popular sites. Substack Help says a post's stats page shows "Popular sites" when readers arrive from social media links, for example Facebook.
  • Meta pixel. If you run ads, Substack's Analytics settings have a Facebook pixel ID field. Substack Help says the pixel reports when someone who clicked your Facebook or Instagram ad takes an action on your publication, such as subscribing.

Facebook already tried newsletters

Facebook once ran its own newsletter product. Meta launched Bulletin in summer 2021 for independent writers, and on 4 October 2022 announced it would shut Bulletin down by early 2023, TechCrunch and Nieman Lab reported. Writers kept their subscription revenue until the shutdown, and they had access to their subscribers' email addresses so they could move their newsletters elsewhere.

How to run both without doubling the work

A simple loop:

  • Write the idea once as a Note.
  • Expand it for Facebook. Take the Note that got the most replies, add context, and post the full thought on your profile or Page with your Substack link at the end.
  • Share to the right Group. Follow its rules, and expect some posts to wait for admin approval.
  • Check what Facebook sends you. If Facebook shows up under "Popular sites" on a post's stats, the loop is working.

Facebook has its own scheduler. Facebook Help says you can schedule a Page post from Meta Business Suite, between 20 minutes and 29 days ahead, and that Group admins and moderators can schedule posts in a Group they manage. For Notes timing, the native composer works, and our guide to schedule Substack Notes compares your options.

If you'd like one queue for both, Buffer is a friendly pick. Buffer's pricing page lists Facebook Pages with automatic publishing, Facebook Groups with reminders to post, and Substack among its channels. Its Free plan connects up to 3 channels with 10 scheduled posts per channel (checked 1 November 2026; Buffer says its pricing was last updated in November 2025). Our guide to using Buffer with Substack Notes walks through the setup.

FAQ

Is Substack better than Facebook for writers?

For a list of readers you keep, Substack wins for most writers: readers can subscribe from a Note in one tap and get your posts by email. Facebook reaches far more people (Meta counted 3.64 billion daily users across its apps in September 2026), but your reach there depends on Facebook's feed.

Is Substack Notes like Facebook?

Notes works like a feed of short posts with likes, comments and restacks, a bit like a Facebook timeline built only for writers and readers. The big difference is the subscribe button: a Note can turn a reader into a subscriber of your publication in one tap.

Should I share my Substack posts on my profile, a Page or a Group?

Start where your readers already are. Your profile reaches friends and family. A Page gives you a public presence that anyone can follow. Groups reach people around a topic, under each Group's own rules. Substack advises sharing the full idea, then the link.

How do I share a Substack post on Facebook?

Copy the post link and share it with a few sentences of the actual idea. Substack says Facebook rewards substantial posts, and suggests tagging @followers in the comments. Check the social preview first in the post editor's Settings, with an image of at least 1200 x 630.

Can I find my Facebook friends on Substack?

Yes. Substack Help says you can connect your Facebook to your Substack account to follow friends and discover creators. You can also sync your phone contacts in the Substack app (Substack Help, updated October 2026).

How do I see if Facebook sends me subscribers?

Open a post's stats. Substack Help says it lists "Popular sites" when readers come from social media links such as Facebook. If you run Facebook or Instagram ads, add your Meta pixel ID in Substack's Analytics settings to see when ad clicks turn into subscribers.

Can I schedule Substack Notes and Facebook posts together?

Each app has its own scheduler: Substack for Notes, Meta Business Suite for Pages. For one queue across both, Buffer connects Facebook Pages for automatic posting, sends reminders for Groups, and connects Substack (buffer.com, checked 1 November 2026).

Did Facebook ever have its own Substack?

Yes. Meta launched Bulletin, a newsletter product for independent writers, and announced its shutdown in October 2022, winding it down by early 2023. Writers kept their subscriber lists (TechCrunch and Nieman Lab, October 2022).

The short version

Notes turns attention into subscribers in one tap. Facebook puts your writing in front of friends, Page followers and Groups who already know you, as long as each post carries the full idea and a link. Write on Notes daily, bring your strongest ideas to Facebook as complete posts, and let "Popular sites" tell you what's working. For the other platforms, see Substack Notes vs Twitter, Substack Notes vs Bluesky, Substack vs Mastodon, Substack Notes vs LinkedIn posts, Substack vs Instagram and Substack vs TikTok.

If Notes is your home base, WriteStack lets you plan and schedule Substack Notes ahead, publishing through Sync plus the Chrome extension. More than 100 Substack bestsellers use WriteStack.
