Notable Positions
On Timing
"Our products didn't work until Q2 2024. Every email went to spam for the first six months. We spent a year optimizing deliverability. The LLMs just weren't good enough before Claude 4."
On Real Metrics
Shares SaaStr's actual Artisan data publicly:
- 21,000 messages sent (~5 months)
- 7.5% overall response rate
- 4.5% positive response rate
- Response rate improving over time through autonomous optimization
On Multivariate Testing
"We test 10+ variants of pain points, solutions, CTAs, and proof points simultaneously. We found that two lowercase words in subject lines outperform everything else. Humans can't process data at this scale."
On Warm vs Cold
"Warm outbound performs 2-3x better than cold on average. Most companies have hundreds of thousands of unnurtured contacts in their CRM."
Key Quotes
- "Two lowercase words in subject lines work best."
- "Sunday afternoon is the best time to email founders."
- "Every email it sends, read it. Some will be dumb."
