SEO Meta Description: Explore how Podzy can assist newsletter creators in scaling their audience by converting successful newsletters like Tangle into engaging podcasts, maximising reach and revenue.

Introduction

Newsletters are everywhere. We subscribe, but seldom find time to read. Enter podcasts. A medium built for busy lives.

In this successful newsletter case study, we look at how Isaac Saul’s Tangle grew into a million-dollar newsletter—and how you can mirror that success. The secret? Turning text into audio.

Podzy offers the tools you need. Let’s dive in.

The Tangle Story: From Text to Millions

Isaac Saul started Tangle as a weekly rundown of global developments. No fluff. Just insights.

Subscribers quickly soared past 100,000.
Revenue hit seven figures in under two years.
Readers praised its clarity and timeliness.

What made Tangle stand out? Consistency. Value. And, most importantly, strong branding.

Yet, a large audience of busy professionals still struggled to read every issue. They wanted to listen.

Why Podcasting Matters

Audio consumption is booming.

75% of podcast listeners multitask.
Global podcast ad revenue is set to exceed $1.6 billion by 2025.
Commuters, exercisers, learners—they all love podcasts.

A successful newsletter case study often ends with a single channel: email. But why stop there? Adding audio creates:

Extended reach. You tap into podcast platforms.
Higher engagement. People listen on the go.
New revenue streams. Sponsorships, ads, memberships.
