## 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"

**Keep under 50 characters.** Mobile truncates at ~35.
