Shorten Substack Links
Substack has become the go-to platform for independent writers, journalists, and creators who want to build a direct relationship with their audience through email newsletters. The platform handles publishing, distribution, and payments, letting writers focus on their craft. But when it comes time to promote your Substack outside of the platform itself, the URLs can work against you.
A typical Substack post URL follows the pattern yourpublication.substack.com/p/your-post-title-in-full-slug-form. For posts with long titles, the slug can stretch the URL well past 80 characters. And if you are sharing a link to your publication homepage or archive page, the subdomain structure still results in a URL that looks unfamiliar to people who are not already Substack users. When you are trying to win new subscribers from Twitter, LinkedIn, or a podcast appearance, every bit of friction counts.
A short link eliminates that friction entirely. Instead of sharing a URL that exposes the Substack infrastructure, you share something like iu.pe/my-newsletter — clean, branded, and immediately communicative about where the link leads.
Why Shorten Substack Links?
Branded newsletter links that drive subscriptions. Growing a Substack audience means promoting your publication everywhere — in your social media bios, at the end of podcast guest appearances, in conference talks, and across other newsletters. A custom shortcode like iu.pe/weekly-dispatch serves as a persistent, memorable URL that you can share verbally, print on business cards, and drop into any bio field. It is far easier for someone to remember and type than a full Substack URL with a subdomain and slug. You can even point it at your publication homepage so that new visitors land on your subscribe page rather than a specific post.
Track which social platforms drive subscribers. Substack provides aggregate subscriber analytics, but it does not tell you precisely which external link drove each subscription. When you create a unique short link for each promotion channel — one for your Twitter bio, one for your LinkedIn posts, one for your podcast show notes — LinkDisguiser tracks the clicks on each independently. Over weeks and months, this data reveals where your most engaged audience lives. If your Twitter link gets 500 clicks but your LinkedIn link gets 200 clicks that convert at a higher rate, you can adjust your promotion strategy accordingly.
Cleaner sharing in Twitter and LinkedIn bios. Social media bios are prime real estate for newsletter writers. You get a single clickable link, and it needs to count. A full Substack URL with subdomain and path looks cluttered in a Twitter or LinkedIn bio. A short link like iu.pe/subscribe is concise, professional, and leaves room for your actual bio text. If you publish on multiple platforms — maybe a Substack and a podcast — you can use different shortcodes for each and track which bio link gets more traction.
Referrer analytics showing your audience sources. Understanding where your readers discover your newsletter is crucial for sustainable growth. LinkDisguiser provides a referrer breakdown for every short link, showing you exactly which websites, apps, and platforms send traffic your way. This goes beyond what Substack natively offers and gives you a complete picture of your promotion funnel. You can see whether a guest post on another blog actually drove clicks, or whether that Reddit thread you commented on generated any real interest.
How to Shorten a Substack Link
Step 1: Copy your Substack URL. Navigate to the specific post or publication homepage you want to promote. Copy the URL from your browser's address bar. If you want to promote your publication in general rather than a specific post, use your publication homepage URL (e.g., yourname.substack.com).
Step 2: Paste it into LinkDisguiser. Visit LinkDisguiser and paste the Substack URL into the input field. For a branded shortcode — something that matches your publication name, like iu.pe/tech-weekly — sign in with Google and type your preferred code.
Step 3: Share across all your channels. Copy the generated short URL and place it in your social media bios, email signatures, podcast show notes, guest post author bios, and anywhere else you promote your newsletter. Each click is tracked with referrer data, giving you visibility into which channels are actually working.
Step 4: Review your analytics regularly. Check your LinkDisguiser dashboard after each publication to see how your promotion links performed. Compare click-through rates across channels and adjust your strategy based on what the data tells you. Over time, you will build a clear picture of the most efficient path to growing your subscriber list.
