How it works

How to create a Substack deep link

Paste your Substack link

Drop any newsletter, post, or Note URL from substack.com into the box above.

Get your deep link

U2L returns a short link that knows how to open the Substack native app on a phone.

It opens in the app

Use it in bios, ads, or a QR code - taps land on the exact post or publication in the Substack app.

What is a Substack deep link?

A Substack deep link is a URL that opens a specific newsletter, post, or Note inside the Substack mobile app rather than a browser. You generate one from any substack.com link and use it wherever you grow your audience.

Writers use deep links so a tap lands in the app, where readers subscribe, read, and follow Notes - and where push notifications keep them coming back. A post opened in a browser is one tap further from a subscribe.

Three terms to know: a deep link is the general idea of opening a specific in-app screen, a universal link is Apple's https-based version on iOS, and an app link is Android's. U2L applies the right one per device, so there's nothing to configure.

There's no SDK or code, either. U2L generates the link from a paste - free and instant.

Can I deep-link to a post or Note?

Yes - paste the post or Note URL and the link opens that exact item in the app.

What's the difference between a deep link and a universal link?

A deep link is the general concept of opening a specific in-app screen; a universal link is Apple's https-based way of doing it on iOS (Android's version is an app link). U2L handles the right one per device automatically.
