- Tag with categories and relevance score
- Note key quotes or takeaways
- Track sources for diversity
EVALUATE (1 day before send):
- Review all saved items
- Score each on: relevance, timeliness, quality, uniqueness
- Select top items per section
- Verify links still work
- Check for duplicates from prior editions
CURATE (writing day):
- Write brief annotations for each item (why it matters)
- Arrange in priority order
- Write featured story and transitions
- Add editorial perspective where appropriate
REVIEW (before send):
- Proofread all copy
- Test all links
- Preview in email client (desktop + mobile)
- Check accessibility (alt text, contrast)
- Send test to 2-3 reviewers
Content Scoring Matrix
| Criterion | Weight | 5 (Include) | 3 (Maybe) | 1 (Skip) |
|---|
| Relevance | 30% | Directly applicable | Tangentially related | Off-topic |
| Timeliness | 25% | This week / breaking | This month | Old news |
| Quality | 20% | Expert source, data-backed | Good but generic | Listicle / fluff |
| Uniqueness | 15% | Unlikely readers saw it | Moderately circulated | Viral / everywhere |
| Actionability | 10% | Clear takeaway or action | Informational | Abstract / theoretical |
THRESHOLD:
3.5+: Definite include
2.5-3.4: Include if space permits
< 2.5: Skip unless slow news week
Tone and Voice Guidelines
Voice Framework by Audience
INTERNAL NEWSLETTER VOICE:
Personality: Friendly colleague who's well-informed
Tone: Warm, transparent, sometimes playful
Language: First-person plural ("we"), casual contractions
Avoid: Corporate jargon, overly formal language, spin
EXAMPLE:
"Big week for the product team — they shipped the new
dashboard that's been in the works since Q3. If you haven't
tried it yet, you're missing out. Here's a quick walkthrough."
──────────────────────────────────────────────────────
EXTERNAL NEWSLETTER VOICE:
Personality: Trusted industry insider
Tone: Authoritative but approachable, value-focused
Language: Second-person ("you"), professional but not stiff
Avoid: Self-promotion overload, clickbait, assumptions
EXAMPLE:
"This week, three major shifts in the data infrastructure
space caught our attention. Here's what they mean for your
stack — and what to do about it."
Annotation Style Guide
CONTENT ANNOTATION FORMULA:
[HEADLINE] (linked)
[1-2 sentence summary of what it covers]
[1 sentence on why it matters to your audience]
EXAMPLE:
"The State of Developer Experience 2025" (link)
GitHub's annual report surveying 12,000 developers on tooling,
AI adoption, and workflow satisfaction. Worth reading for the
data on how teams are actually using AI coding assistants —
the gap between hype and reality is illuminating.
BAD ANNOTATION:
"The State of Developer Experience 2025" (link)
Check out this report from GitHub.

Layout and Formatting Best Practices
Email Design Principles
FORMATTING RULES:
WIDTH:
- Max content width: 600px
- Single column preferred (reliable rendering)
- 2-column only for desktop-specific sections
TYPOGRAPHY:
- Body: 16px minimum (mobile readability)
- Headlines: 20-24px
- Line height: 1.5-1.6
- Font: System fonts or web-safe (Arial, Georgia, Helvetica)
IMAGES:
- Width: 100% of container (responsive)
- Alt text on every image
- File size: < 200KB per image
- Use sparingly — many clients block images by default
SPACING:
- Section dividers between major sections
- Generous padding (20px+) between items
- White space > cramped content
MOBILE:
- Test on iOS Mail, Gmail app, Outlook app
- Buttons: minimum 44x44px touch target
- Text should be readable without zooming
- Stack columns vertically on mobile
