Every email
What you’ll get
- One clear idea per email you can use on your next big decision.
- Real stories from deals, mistakes, and conversations — not theory.
- Simple breakdowns of tradeoffs like sell vs hold, cash now vs more later, speed vs price.
- Short reads that respect your time: no fluff, no “crush it” speeches.
The reason
Why I write it
I’m picky about emails. I hate long, fluffy messages that don’t change anything. The Julian Castle Letter is what I’d want in my own inbox: quick, useful, and focused on real decisions with real money on the line.
My goal is simple: every email gives you one idea that makes a hard choice a little easier.
