| Source Type | Examples | Best For |
|---|---|---|
| News | TechCrunch, The Verge, industry press | Breaking developments |
| Research | Papers, reports, surveys | Data-backed insights |
| Blogs | Engineering blogs, personal blogs | Practitioner perspectives |
| Social | Twitter threads, LinkedIn posts | Hot takes, discussions |
| Tools | Product launches, updates | Practical recommendations |
| Community | Reddit, HN, forums | Ground-level sentiment |
For each piece of content, ask:
| Question | If No → |
|---|---|
| Would I send this to a colleague 1-on-1? | Don't include |
| Does it teach something actionable? | Consider skipping |
| Is the source credible? | Find better source |
| Is it timely/relevant this week? | Save for later or skip |
| Can I add commentary that adds value? | Just linking isn't enough |
❌ 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."
[What happened] + [Why it matters to the reader] + [Your take or prediction]
| 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) |
| 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.
| Strategy | Implementation |
|---|---|
| Cross-promotion | Partner with complementary newsletters |
| Social distribution | Post key insights on Twitter/LinkedIn with subscribe CTA |
| Referral program | "Forward to 3 friends" or formal referral rewards |
| SEO archive | Publish newsletter archive as blog posts |
| Lead magnet | "Subscribe and get [free resource]" |
| Consistent quality | The best growth strategy: be worth reading |
# Create social teaser for newsletter
belt app run x/post-create --input '{
"text": "This week in The Weekly Signal:\n\n→ Why edge computing is eating the backend\n→ The database migration nobody talks about\n→ 5 tools I discovered this month\n\nJoin 2,000+ engineers: [link]\n\nIssue #47 drops tomorrow morning."

| 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 |
| No personal voice | Reads like an RSS feed | Intro paragraph, opinions, personality |
| Only promotional content | Readers unsubscribe | 90% value, 10% promotion max |
| Inconsistent quality | Trust erodes | Skip an issue rather than send a weak one |
| No CTA for engagement | One-way broadcast | Ask questions, invite replies, encourage forwards |
