The Crowned Projects.

Where ideas wear the crown

Are you ready to explore the King’s projects? Step into the world of newsletters built on ideas, experimentation, and real growth.

👑 Projects With Real Impact: Experiments, tools, and systems designed to grow newsletters beyond dashboards and vanity metrics. Each project is crafted to spark engagement, inspire ideas, and capture readers’ attention.

🌐 Projects Built Differently: Every project showcased here is about experimentation, creativity, and building newsletters people actually want to read. These are the real wins beyond the metrics.

📊 Why Numbers Don’t Rule: The King of the Newsletter no longer trusts hard metrics. Private mode blocks tracking. Apple Mail Privacy Protection inflates open rates. Safari limits data collection. Ad blockers remove pixels. Cross-domain tracking is unreliable. Conversion and attribution models are increasingly untrustworthy, stitching together incomplete data and presenting it as certainty – and so on! That’s why flashy figures don’t appear here. The King believes in the story behind the numbers — the real signals that show why something works.

💰 Want To See Numbers Anyway? Contact the King. He’ll showcase you meaningless numbers, even that email marketing generated €3+ million for one client — but even that figure doesn’t add value to business.
