Substack has comments. But a reader has to sign in to Substack to leave one, and many writers limit comments to paid subscribers.
If comments are paid-only and most readers are on the free tier, the comment section stays quiet. Even when comments are open to everyone, the sign-in step stops a lot of readers. The people who actually engaged with your writing end up saying nothing.
The gap Substack doesn't fill
Every platform-native comment system assumes readers already have a stake in the ecosystem.
Substack: a Substack account, often a paid subscription. Beehiiv: account required. Ghost: member sign-in. What none of them offer: a reader who found your archive through a search result, a forwarded link, or a recommendation — that reader leaves no trace.
A different approach
Add a Joey link to your newsletter or your web archive page.
Readers click through to a comment box. No account, no subscription, no login. They leave a line. That's it.
The reactions collect in a dashboard you own. You can read them, reply, and export to CSV. They're not locked inside Substack — they stay with you if you ever move.
How it compares to self-hosted tools
Open-source comment systems like Remark42 and Isso are free if you run your own server. Joey is hosted: nothing to install, no Docker setup, and the comment box works in English, Korean, and Japanese. There's a longer comparison in Disqus alternatives in 2026.
Where to put the link
At the end of your newsletter email:
Or on your Substack archive page, in a pinned post, or your about page. Anywhere a reader might land.
The readers you're not hearing from aren't disengaged. They just don't have a low-friction way to respond. Joey adds that.
