Substack Link Shortener

Yes. Paste any Substack newsletter, post, or subscribe page URL and Flyn creates a short, branded link.

Yes. Share branded links on social media and track which platforms drive the most subscriber clicks.

Flyn tracks clicks on the subscribe link. For actual subscription data, check Substack analytics.

Yes. All Substack URLs including paid posts, free previews, and archive pages can be shortened.

Yes. Print flyn.to/subscribe or go.yourbrand.com/newsletter for a clean call-to-action.

Yes. Substack registers Universal Links for substack.com and *.substack.com URLs on iOS and Android, so a Flyn link redirecting to a post or newsletter opens the Substack app when installed. Readers without the app see the post in their mobile browser, where Substack offers an "Open in app" prompt.

Yes. Use a memorable slug like flyn.to/latest in your bio, podcast description, and email signature. Each time you publish a new issue, take 10 seconds to update the destination URL inside Flyn, every place you've shared the short link automatically points to your newest piece without re-editing any external references.

Yes. Notes URLs (substack.com/notes/...) and Chat thread URLs both shorten and track normally. Use Flyn to drive readers from your newsletter to your Notes feed (warming up cross-platform engagement), or to invite subscribers to a specific Chat thread for paid-tier discussions.

Create a unique Flyn link per guest essay or podcast appearance, flyn.to/sub-bensthompson, flyn.to/sub-myfirstmillion. Flyn shows clicks per source; Substack shows new paying subscriber acquisition over the same window. The intersection tells you exactly which guest spot earned its place in your promotion calendar.

Yes. With Flyn Pro's A/B testing, point one short link at two paid-tier landing variations, different copy, different stacked benefits, different price anchoring. Half your visitors see variant A, half see variant B; cross-reference Substack subscription conversions over the test window to declare a winner.

Yes. When a reader arrives via a Flyn link and subscribes, Substack's Recommendations engine still triggers based on their subscription pattern, the redirect is invisible to Substack's recommendation logic. Flyn handles the URL hop; Substack handles the cross-newsletter recommendation prompt.

Very. Podcast hosts often promote a guest's newsletter at the end of an interview. Give the guest a unique Flyn link per show (flyn.to/sub-from-tim, flyn.to/sub-from-lenny) so the guest can attribute exactly how many subscribers each podcast appearance generated, invaluable data for prioritizing future podcast spots.

No. Flyn is a full URL shortener that works with any link: Substack, your own website, YouTube, Etsy, affiliate links, PDFs, anything with a URL. This page just shows the Substack use case. Every feature here (click analytics, editable destinations, branded domains, QR codes) applies to every link you shorten.
