Draft and design a complete HTML email newsletter from a topic or content brief. Output is paste-ready for Loops, Mailchimp, Beehiiv, Resend, or any standard email platform.
Critical rule: Table-based HTML with inline styles only. No CSS classes, no flexbox, no grid, no <style> blocks. Every element gets style="" directly. This is not optional -- email clients strip everything else.
Need three things to start. If all three present in the message: skip to Step 2.
If any missing, ask exactly:
"To get started, I need three things:
- Topic -- what is this newsletter about?
- Audience -- who is reading? (role, company size, how they know you)
- Primary CTA -- what one action do you want readers to take?"
Wait for all three before continuing.
Ask all questions in one message, grouped by category. User can skip any -- defaults apply.
"A few questions before I draft -- answer what you know, skip the rest:
Content
- Length -- brief (300 words, punchy) / standard (500-700) / deep dive (800+ words)?
- Format -- editorial article / numbered breakdown / personal story / data report?
- Issue context -- one-time send / part of weekly series / monthly digest?
- CTA URL -- what's the actual link? (or I'll use a placeholder)
Brand 5. Company / brand name -- for header and footer 6. Tagline -- one-line description (optional, for footer) 7. City & country -- for footer (e.g. "San Francisco, US") 8. Primary brand color -- hex? (e.g. #856FE6) 9. Secondary accent -- keep default yellow-green (#D8F90A) / use brand color / something else?
Design 10. Background -- dark (editorial/SaaS) / light (clean/corporate) / custom hex? 11. Display font -- editorial serif (Instrument Serif) / clean modern sans / system fonts only? 12. Button style -- pill (very rounded) / softly rounded / sharp corners? 13. Visual style -- editorial / technical+data / warm+founder / bold+campaign?
Platform & Technical 14. Platform -- Loops / Mailchimp / Beehiiv / Resend / other? 15. Tone -- educational / conversational / bold+direct / formal / playful? 16. Personalization -- none / first name / first name + company? 17. Subject line -- have one / want 3 options? 18. Secondary sections -- sponsor block / product callout / event / quick links / none? 19. Plain-text version -- yes (recommended) / no?"
Defaults if skipped:
| Question | Default |
|---|---|
| Length | standard (500-700 words) |
| Format | editorial article |
| Issue context | one-time send |
| CTA URL | [CTA_URL] placeholder |

From Step 2 answers, determine:
Character defaults if question 13 skipped:
Never ask the user for design direction separately -- derive it from their answers.
Read references/html-email-guide.md for layout rules before choosing sections.
Based on topic + audience + CTA + secondary sections requested, select sections from this library:
| Section | Include when |
|---|---|
| header | Always -- logo placeholder + issue number or date |
| hero | Always -- big headline + 1-2 sentence hook |
| intro | Conversational or educational tone -- short personal note |
| main-content | Primary article or insight (text-heavy) |
| stat-callout | There is a compelling stat, quote, or data point |
| secondary-section | Secondary CTA was requested |
| product-cta | Brand context present and soft product plug fits |
| sponsor-block | Sponsor section was requested |
| quick-links | Curated links section was requested |
| footer | Always -- unsubscribe link + company name |
Output the chosen structure as a numbered list with one-line purpose per section:
Proposed structure:
1. Header -- logo + Issue #1 / [date]
2. Hero -- headline + hook paragraph
3. Intro -- short personal framing
4. Main Content -- [topic] breakdown
5. Stat Callout -- key data point from the story
6. CTA -- [cta text]
7. Footer -- unsubscribe + company
Does this structure work, or should I adjust any sections?
Wait for confirmation before Step 4.
Write copy for each section in sequence. No HTML yet -- clean prose only.
Rules per section:
Read references/subject-line-formulas.md then write 3 subject line options (if subject line not provided by user):
Do not use em dashes. Do not use: "powerful", "seamless", "game-changing", "leverage", "innovative", "unlock", "transform", "elevate", "cutting-edge", "robust".
Read references/design-system.md and references/html-email-guide.md before generating HTML.
Template or custom -- decide based on Step 2 answers:
Use templates/dark-newsletter.html as base when ALL of:
Use templates/light-newsletter.html as base when ALL of:
Generate custom HTML from scratch when ANY of:
For custom generation: use references/design-system.md Custom Generation Guide as the full token spec. Apply user's background/font/button/accent choices throughout.
Then (for template path):
[PLACEHOLDER] values with content from Step 4[UNSUBSCRIBE_URL] placeholders are still present (platform tuning happens in Step 6)Brand color substitution rules:
If brand_color is provided:
bgcolor (#D8F90A in the height:2px row) with brand_color#D8F90A with brand_color too#D8F90A, only use brand_color for strip + stat borderIf brand_color is NOT provided: keep all #D8F90A values as-is.
Content substitution rules (from Step 2 answers):
company_name provided: replace all [YOUR BRAND] and [COMPANY NAME] placeholderscity_country provided: replace [CITY, COUNTRY] placeholdertagline provided: add as subtitle line in footer after company namecta_url provided: replace all [CTA_URL] placeholders with actual URLpersonalization = first_name: add platform-appropriate first name variable to hero greeting -- e.g. Hey %%first_name%%, on Beehiiv, Hey {{first_name}}, on Loops, Hey *|FNAME|*, on Mailchimppersonalization = first_name + company: add both variables where contextually appropriateBrand color visual tension check (on dark email):
Does the brand color visually pop on #111111? Test mentally: would it be visible as a 2px strip?
#555555#2A2A2A): skip brand_color for ALL accent uses, fall back to #D8F90A for every elementAccent discipline rule: brand_color appears in AT MOST 3 places: brand strip, stat border, category label. Never in body copy, headlines, button backgrounds, or section backgrounds. Over-branding kills the premium feel.
CTA button text color:
#D8F90A button background: always use #0A0A0A text (it's a light color)#111111 button background (inside yellow callout card): always use #F2F2F2 text#0A0A0A if brand is light, #FFFFFF if brand is darkRequired on every <td> with a background color:
Both the bgcolor= HTML attribute AND the inline background-color: style. Example:
<td bgcolor="#D8F90A" style="background-color:#D8F90A;">
The attribute handles Outlook. The style handles everything else. Never use just one.
Design excellence (frontend-design principles, email-adapted):
Email's table constraints don't limit design ambition. Push within them:
Typography to its extreme: 4-5 word headlines = 60px, -0.04em tracking. 6-7 word headlines = 56px, -0.03em. 8 words = 48px. Never size down for safety -- the headline is a poster, not a label. Instrument Serif italic on stat quotes adds literary weight no other element can match.
Density contrast as craft signal: Hero = maximum open space (64px top). Body paragraphs = tight and dense. CTA callout card = maximum open space again (64px). Open → tight → open is the rhythm that reads as intentional design, not template output.
Background depth via section alternation (all email-safe):
#0A0A0A#111111#111111, inner elevated card: #1A1A1A#161616 (subtle elevation creates depth without color)#111111 (contrast with body)#D8F90A (the ONLY bright element -- never dilute)name: email-newsletter description: Drafts and designs a complete HTML email newsletter from a topic or content brief.

# Email Newsletter
Draft and design a complete HTML email newsletter from a topic or content brief. Output is paste-ready for Loops, Mailchimp, Beehiiv, Resend, or any standard email platform.

## Step 1: Brief Intake
Need three things to start. If all three present in the message: skip to Step 2.
If any missing, ask exactly:
> "To get started, I need three things:

**Defaults if skipped:**
| Question | Default |
|---|---|
| Length | standard (500-700 words) |
| Format | editorial article |
| Issue context | one-time send |
| CTA URL | `[CTA_URL]` placeholder |
| Company name | `[YOUR BRAND]` placeholder |
| Tagline | none |
| City & country | `[CITY, COUNTRY]` placeholder |
| Brand color | none (use `#D8F90A` for all accents) |
| Secondary accent | `#D8F90A` (yellow-green default) |
| Background | dark |
| Display font | Instrument Serif (editorial serif) |
| Button style | pill |
| Visual style | editorial |
| Platform | generic |
| Tone | conversational |
| Personalization | none |
| Subject line | generate 3 options |
| Secondary sections | none |
| Plain-text | yes |
---
## Step 2.5: Design Direction (internal -- not shown to user)
From Step 2 answers, determine:
- Visual character (from question 13, or inferred from tone + format if skipped)
- ONE unmissable element -- identify before Step 3
- Template path (see Step 5)
Character defaults if question 13 skipped:
- Educational / formal tone: Editorial
- Metrics-heavy content (stats, benchmarks, reports): Technical/data-forward
- Product launches, events, campaigns: Bold/campaign
Never ask the user for design direction separately -- derive it from their answers.
---
## Step 3: Structure Design
Read `references/html-email-guide.md` for layout rules before choosing sections.
Based on topic + audience + CTA + secondary sections requested, select sections from this library:
| Section | Include when |
|---|---|
| header | Always -- logo placeholder + issue number or date |
| hero | Always -- big headline + 1-2 sentence hook |
| intro | Conversational or educational tone -- short personal note |
| main-content | Primary article or insight (text-heavy) |
| stat-callout | There is a compelling stat, quote, or data point |
| secondary-section | Secondary CTA was requested |
| product-cta | Brand context present and soft product plug fits |
| sponsor-block | Sponsor section was requested |
| quick-links | Curated links section was requested |
| footer | Always -- unsubscribe link + company name |
Output the chosen structure as a numbered list with one-line purpose per section:
```
Proposed structure:
1. Header -- logo + Issue #1 / [date]
2. Hero -- headline + hook paragraph
3. Intro -- short personal framing
4. Main Content -- [topic] breakdown
5. Stat Callout -- key data point from the story
6. CTA -- [cta text]
7. Footer -- unsubscribe + company
Does this structure work, or should I adjust any sections?
```
Wait for confirmation before Step 4.
---
## Step 4: Content Draft
Write copy for each section in sequence. No HTML yet -- clean prose only.
**Rules per section:**
- **Header**: Issue number + date. No copy needed.
- **Hero headline**: 8 words max, outcome-focused, no starting with "I/We/Our"
- **Hero hook**: 1-2 sentences, problem or curiosity gap, pulls reader in
- **Intro**: 2-3 sentences, personal or contextual, not corporate-speak, contractions OK
- **Main content**: 250-400 words, scannable -- use **bold phrases** for key points, short paragraphs (1-3 lines), no walls of text, no bullet overload
- **Stat callout**: One stat or quote, 20 words max, punchy
- **Product CTA**: 2-3 sentences, value-forward, not "Check out our product" -- tell them what changes for them
- **CTA button text**: 3-5 words, action verb + benefit ("Read the full breakdown", "Save my seat", "Get the guide")
- **Footer**: Unsubscribe link placeholder + company name
Read `references/subject-line-formulas.md` then write 3 subject line options (if subject line not provided by user):
- Option A: Curiosity gap formula
- Option B: Direct benefit formula
- Option C: Number/list formula
Do not use em dashes. Do not use: "powerful", "seamless", "game-changing", "leverage", "innovative", "unlock", "transform", "elevate", "cutting-edge", "robust".
---
## Step 5: HTML Generation
Read `references/design-system.md` and `references/html-email-guide.md` before generating HTML.
**Template or custom -- decide based on Step 2 answers:**
**Use `templates/dark-newsletter.html` as base when ALL of:**
- background = dark (or not specified)
- display font = Instrument Serif (or not specified)
- no custom background hex provided
**Use `templates/light-newsletter.html` as base when ALL of:**
- background = light OR tone = formal
- display font = Instrument Serif (or not specified)
- no custom background hex provided
**Generate custom HTML from scratch when ANY of:**
- custom background hex provided (not dark, not white)
- display font = modern sans or system fonts only
- combination of answers produces a design neither template serves
For custom generation: use `references/design-system.md` Custom Generation Guide as the full token spec. Apply user's background/font/button/accent choices throughout.
**Then (for template path):**
1. Select only the sections needed from the template (based on Step 3 structure)
2. Fill in all `[PLACEHOLDER]` values with content from Step 4
3. Apply brand color substitution (see below)
4. Verify all `[UNSUBSCRIBE_URL]` placeholders are still present (platform tuning happens in Step 6)
**Brand color substitution rules:**
If `brand_color` is provided:
- Replace brand strip `bgcolor` (`#D8F90A` in the `height:2px` row) with brand_color
- Replace stat callout left border color with brand_color
- Replace category label color with brand_color
- If brand_color luminance is high (yellows, greens, oranges -- most neons): replace step badge `#D8F90A` with brand_color too
- If brand_color luminance is low (dark navy, forest, charcoal): keep step badges and CTA button as `#D8F90A`, only use brand_color for strip + stat border
If `brand_color` is NOT provided: keep all `#D8F90A` values as-is.
**Content substitution rules (from Step 2 answers):**
- If `company_name` provided: replace all `[YOUR BRAND]` and `[COMPANY NAME]` placeholders
- If `city_country` provided: replace `[CITY, COUNTRY]` placeholder
- If `tagline` provided: add as subtitle line in footer after company name
- If `cta_url` provided: replace all `[CTA_URL]` placeholders with actual URL
- If `personalization = first_name`: add platform-appropriate first name variable to hero greeting -- e.g. `Hey %%first_name%%,` on Beehiiv, `Hey {{first_name}},` on Loops, `Hey *|FNAME|*,` on Mailchimp
- If `personalization = first_name + company`: add both variables where contextually appropriate
**Brand color visual tension check (on dark email):**
Does the brand color visually pop on `#111111`? Test mentally: would it be visible as a 2px strip?
- High-saturation colors (purples, blues, teals, pinks, yellows, oranges, greens): YES -- use for strip + stat border + category label
- Low-saturation / near-neutral (warm greys, beige, off-white): strip only; category label reverts to `#555555`
- Near-black (very dark navy, forest, charcoal below ~`#2A2A2A`): skip brand_color for ALL accent uses, fall back to `#D8F90A` for every element
**Accent discipline rule:** brand_color appears in AT MOST 3 places: brand strip, stat border, category label. Never in body copy, headlines, button backgrounds, or section backgrounds. Over-branding kills the premium feel.
**CTA button text color:**
- On `#D8F90A` button background: always use `#0A0A0A` text (it's a light color)
- On `#111111` button background (inside yellow callout card): always use `#F2F2F2` text
- On brand_color button: use `#0A0A0A` if brand is light, `#FFFFFF` if brand is dark
**Required on every `<td>` with a background color:**
Both the `bgcolor=` HTML attribute AND the inline `background-color:` style. Example:
```html
<td bgcolor="#D8F90A" style="background-color:#D8F90A;">
```
The attribute handles Outlook. The style handles everything else. Never use just one.
**Design excellence (frontend-design principles, email-adapted):**
Email's table constraints don't limit design ambition. Push within them:
- **Typography to its extreme**: 4-5 word headlines = 60px, `-0.04em` tracking. 6-7 word headlines = 56px, `-0.03em`. 8 words = 48px. Never size down for safety -- the headline is a poster, not a label. Instrument Serif italic on stat quotes adds literary weight no other element can match.

- **Background depth via section alternation** (all email-safe):
- Header: `#0A0A0A`
- Hero: `#111111`
- Stat callout outer: `#111111`, inner elevated card: `#1A1A1A`
- Body paragraphs: `#161616` (subtle elevation creates depth without color)
- Step cards: `#111111` (contrast with body)
- CTA callout card: `#D8F90A` (the ONLY bright element -- never dilute)
- Footer: `#0808Skill source recorded
