I grew my own B2B newsletter from 0 to 18,000 subscribers over four years and have coached dozens of other creators since. My work is with B2B newsletter creators between 1,000 and 50,000 subscribers — the band where the game shifts from 'how do I get started' to 'how do I make this a real business'. Most newsletters I see have one of three problems: they're writing for the wrong audience, they're not asking anything of the reader, or they're shipping too often. We diagnose which one and fix it.
