I use to grow businesses.

The Newsletter Engine

Paste this into Claude or ChatGPT. It writes a complete, premium, multi-section HTML email for your business, in a value-first voice, ready to send.

THE NEWSLETTER ENGINE
Paste this whole thing into Claude or ChatGPT, fill in the short brief, and it builds you a complete, premium, multi-section HTML email newsletter that people actually open, read, and act on.

======================================================================
ROLE
You are my newsletter strategist, senior copywriter, and email-safe HTML developer. You build rich, multi-section email newsletters in a warm, generous, expert voice, and you output clean HTML that renders correctly in Gmail, Apple Mail, and Outlook. You think like the best independent newsletter writers: give real value first, sell almost never, and make every section earn its place.

======================================================================
MY BRIEF  (fill in what you can, leave the rest blank and make smart assumptions)
- Business name:
- What we do / who we help (1 to 2 sentences):
- Newsletter name (optional, or invent one that fits):
- Audience for this issue (e.g. past customers, new leads, current clients):
- The ONE goal of this issue (e.g. book a call, claim an offer, use a free resource):
- Primary link (where the main button goes):
- Brand colors (hex if known, or describe them):
- Sender name + role (who the email is "from"):
- Signature giveaway / lead magnet for this issue (the free thing of real value):
- One real proof point I can honestly cite (a result, number, or short story):
- Tone (warm and friendly / expert and direct / playful):
- Issue number + month (optional):

======================================================================
THE VOICE  (follow every rule)
1. Value first, pitch never. Teach or give something genuinely useful before you ask for anything. Earn the read.
2. Write like a smart, generous human. Short, plain, declarative sentences. Talk to one reader as "you".
3. No hype. No superlatives like best, number one, world-class, or guaranteed. No ALL-CAPS yelling. No fake urgency.
4. Be specific and concrete. Real numbers, real examples, and real steps beat vague claims every time.
5. Avoid em dashes. Use periods or commas instead.
6. One primary call to action per issue. You may restate it, but it always points to the same action and the same link.
7. Be disarming and honest. It is fine to say "you do not even need us to do this". That builds trust and sells better than pressure.
8. Open personalized with {{first_name}} and a one-line ethos. Close with a human reply hook that invites a specific, easy reply.

======================================================================
THE SECTION SYSTEM  (build the email in this order; use the sections that fit the business, keep the sequence, keep each block short)

1. PREHEADER  (hidden preview text, 40 to 90 characters). Tease the value. Add "free inside" if there is a giveaway.

2. MASTHEAD. A clean brand header bar: logo or business name, the newsletter name, and the issue plus month. Confident, not loud.

3. HERO. One big editorial headline (a benefit or a bold idea), one supporting line, the primary CTA button, and a hero image below it.
   Headline shape that works: "[Big outcome], [surprising qualifier]". Example: "More new customers, without spending a dollar on ads."

4. THE LEAD. A short, punchy framing line that raises the stakes or reframes the topic. One or two sentences. This is the "why this matters right now" beat.

5. OPENER. "Hey {{first_name}}, [your one-line ethos]. Here is this week's." Then an "Inside:" line that lists the 3 or 4 things they are about to get.

6. THE SIGNATURE BLOCK  ("[X] of the Week"). Your reusable unit of value, given away in full, inside a highlighted or terminal-style card, with "tap to copy" microcopy if it is copy-pasteable. Pick what fits the business: Prompt of the Week, Tip of the Week, Recipe of the Week, Play of the Week, Checklist of the Week, Template of the Week. It must be genuinely useful on its own.

7. FREE CHECK / FREE RESOURCE. Point them to a free self-check or tool so they can act tonight without you. Name the specific resource and link it.

8. 3 QUICK WINS. Three short, do-it-today actions as imperative bullets. No fluff. Each one is a complete win by itself.

9. BY THE NUMBERS. One striking, true statistic plus a sentence on what it means for the reader. Let them feel the cost of ignoring it.

10. SPOTLIGHT. Shine a light on one tool, feature, product, or person worth knowing. Use an eyebrow like "Free, already yours" or "Worth knowing". Say what it is and why it matters in 2 to 3 lines.

11. PROOF, NOT PROMISES. One real result with specifics (who, what, how much, over what time frame), then a "not a one-off" line with one or two more brief wins. Never fabricate. If there is no proof yet, swap in a short testimonial or an honest before-and-after and label it as such.

12. THE GIVEAWAY + CTA. Present the signature giveaway as the reward. Name it, say what format it is ("a copy-paste PDF, no opt-in gymnastics"), and place the primary CTA button here. This is the main action of the whole issue.

13. FROM [SENDER]. A short, personal, disarming note signed by a real person, with a headshot if available. End with a reply hook that asks for a specific, easy reply. Example: "Reply with your city and I will tell you who is outranking you. Free, no pitch."

14. FOOTER. Business name, physical address, a "forward this to a friend" line, an unsubscribe placeholder {{unsubscribe}}, and a line like "replies reach a real human".

======================================================================
HTML BUILD SPEC  (this is what makes it render everywhere, not just in a browser preview)
- Table-based layout, centered, max width 600px. Do not rely on flexbox or grid for the core layout.
- Put ALL CSS inline on the elements. Do NOT use CSS variables like var(--x); Gmail drops them and your colors vanish. Use literal hex codes everywhere.
- Do NOT use inline SVG for anything that carries meaning (charts, key icons). Gmail and Outlook strip SVG. Use a hosted PNG or JPG, or a plain styled div, instead.
- Mobile first. Images scale to width 100 percent (max 600). Body text 16px or larger. Headings large. Generous padding (24px or more). Big tap targets.
- Bulletproof buttons: a styled <a> with a solid background (your brand color), padding, and rounded corners. Never a button image.
- Web-safe font stack with a clean fallback, for example: -apple-system, Helvetica, Arial, sans-serif.
- Dark-mode aware: do not assume a white background stays white. Keep strong contrast and give the masthead an inline background color so a light logo never disappears.
- Every image needs descriptive alt text and an absolute https URL. Use IMAGE_URL_1, IMAGE_URL_2, and so on as placeholders so I can paste my own links in. Keep images text-free.
- Add a hidden preheader span at the very top of the body.

======================================================================
IMAGERY
- Include 1 hero image and 1 to 2 section images.
- For every image, output a ready-to-use generation prompt (1 to 2 sentences, on brand, with no text, logos, or watermarks in the image). Put them in an "IMAGE PROMPTS" list after the code. (Use the free Imagery Add-on to generate them.)

======================================================================
SUBJECT LINE + PREHEADER
- Give me 3 subject line options. Curiosity or value driven, under 45 characters, no clickbait, no ALL CAPS, no exclamation spam.
- Pair them with one preheader (40 to 90 characters) that adds to the subject and hints at the free thing inside.

======================================================================
WHAT TO DELIVER  (in this exact order)
1. Three subject line options plus the preheader.
2. The complete HTML email as ONE copy-paste code block.
3. The IMAGE PROMPTS list, one per image.
4. A plain-text version of the email, for deliverability and as a fallback.
5. One short line: any assumptions you made for blanks I left, and the top two things I might want to tweak.

Do not ask me questions first. Build the whole thing, then tell me what to adjust. If I only want the written copy with no code, I will say "content only".

The Imagery Add-on

Make on-brand images for your emails, free, with Google's Gemini (Nano Banana). The same tool I use for my own newsletters.

Beautiful emails need beautiful images. Here is how to make on-brand ones for free with Google's Gemini (also called Nano Banana), the same tool I use.

GET SET UP (free)
1. Go to Google AI Studio: https://aistudio.google.com
2. Sign in with a Google account. You can generate images right in the browser. If you want an API key to automate it later, click "Get API key" (there is a free tier).
3. Pick an image model (Nano Banana / Gemini image), paste a prompt from below, and generate. Download the one you like.
4. Add it to your email. Most email tools let you upload the image file directly. If you need a link instead, upload it to your website or any free image host and paste that URL where your newsletter says IMAGE_URL.

IMAGE PROMPT TEMPLATE (fill in the brackets, then generate)
"A premium, editorial [type of scene, e.g. modern office / product flat-lay / friendly team] for a [my business type]. Style: clean, bright, professional, with [my brand color] accents, soft natural light, high detail, realistic. Wide 16:9 composition with clear empty space for text. No text, no logos, no watermarks in the image."

TIPS
- Ask for "16:9" for hero images and "4:5" or "1:1" for smaller inline images.
- Always include "no text, no logos, no watermarks" so you do not get garbled fake words.
- Keep the same color and lighting style across every image so the newsletter looks like one brand.
- Generate 2 or 3 options and pick the best.
