|---|---|
| Would I send this to a colleague 1-on-1? | Don't include |

Writing Commentary#
What Makes Good Commentary#
❌ Just describing: "This article talks about React Server Components."
❌ Restating the headline: "React Server Components are here."
✅ Adding context: "React Server Components shipped last week, and this
is the first production teardown I've seen. Key insight: they reduced
initial JS bundle by 60%, but added complexity to the build pipeline."
✅ Giving your take: "I'm skeptical about the migration path here.
Most teams I've talked to are waiting for better tooling."
✅ Connecting dots: "This pairs well with Vercel's announcement last
month — the ecosystem is clearly converging on this pattern."Commentary Formula#
[What happened] + [Why it matters to the reader] + [Your take or prediction]Sending Cadence#
| Frequency | Best For | Open Rate Impact |
|---|---|---|
| Weekly | Most newsletters | Highest — predictable, not overwhelming |
| Bi-weekly | Deep analysis, essays | Good if content is substantial |
| Daily | News-focused, short format | Requires dedicated habit, risky |
| Monthly | Research roundups | OK for depth, risks being forgotten |
Weekly is the sweet spot. Same day, same time, every week. Consistency builds habit.
| Day | Performance |
|---|---|
| Tuesday | Highest open rates |
| Thursday | Second highest |
| Wednesday | Third |
| Monday | Lower (inbox overload) |
| Friday | Lower (weekend mode) |
| Weekend | Lowest (but some niches thrive) |
Subject Lines#
| Formula | Example |
|---|---|
| Issue number + teaser | "#47: The framework nobody's talking about" |
| Number + topic | "5 tools that changed my workflow this month" |
| Question | "Is TypeScript dying?" |
| This week + category | "This week in AI: GPT-5 rumors, open source wins" |
| Direct value | "The SQL optimization guide I wish I had earlier" |

| Too many links (15+) | Overwhelming, nothing stands out | 5-10 curated picks max |
| Generic subject lines | Low open rates | Tease the best content, keep under 50 chars |
