These aren't theoretical prompts. They're the ones our users have reported generating real, measurable revenue — from booking sales calls to launching products that converted. We've included the exact prompt text for each one.
1. The Cold Email Opener That Gets Replies
This prompt generates a hyper-personalised opening line that references something specific about the prospect — the biggest factor in cold email reply rates.
Write 5 personalised opening lines for a cold email to [PROSPECT NAME] at [COMPANY].
Context about them: [LINKEDIN BIO / RECENT NEWS / PRODUCT LAUNCH]
My offer: [WHAT I DO]
Their likely pain point: [PAIN POINT]
Each opener must:
- Reference something specific about them or their company
- Be under 25 words
- Not mention my product in the first line
- Feel like it was written by a human who did their research
2. The Facebook Ad Copy Generator
You are a performance marketer who has managed £10M+ in Facebook ad spend. Write 3 Facebook ad variations for [PRODUCT/SERVICE].
Target audience: [DETAILED PERSONA]
Offer: [OFFER + PRICE POINT]
Unique mechanism: [WHAT MAKES IT DIFFERENT]
For each ad:
- Hook (first line that stops the scroll — under 8 words)
- Body (problem → agitation → solution, 80-120 words)
- CTA (specific action, not "learn more")
- Headline (title case, benefit-led, under 7 words)
Test angles: fear of missing out, social proof, transformation promise.

Write a 5-minute video sales letter script for [PRODUCT].
Target: [PERSONA] who struggles with [PROBLEM]
Desired outcome: [TRANSFORMATION]
Price point: [PRICE]
Guarantee: [GUARANTEE IF ANY]
Structure:
00:00-00:30 — Pattern interrupt hook (start with the result, not the product)
00:30-01:30 — Problem identification (make them feel seen)
01:30-02:30 — Failed solutions they've already tried
02:30-03:30 — The mechanism (how your product works differently)
03:30-04:30 — Social proof (outcomes, not features)
04:30-05:00 — Offer stack + CTA
Tone: conversational, not salesy. Write as if talking to a friend.
4. The Content Calendar Generator

Write a short email to a happy customer asking for a testimonial that I can use in my marketing.
Product/service: [PRODUCT]
Result they achieved: [SPECIFIC OUTCOME]

The email should:
- Reference their specific result

- Be under 150 words total
Do not use the word "testimonial" — say "quick win story" instead.
