Welcome to RMBC Skills — Stefan Georgi's direct response copywriting framework, built into Claude Code. 44 skills covering hooks, ads, emails, landing pages, VSL scripts, and more.

Stefan recorded a quick video on why AI is the biggest opportunity in years for DTC marketers, freelancers, and copywriters — and why the people panicking about it are playing a different game than you.

Use AskUserQuestion:

• Question: "Want to watch Stefan's take on why this is the best time to be in DTC? (~5 min)"
• Options:
  1. "Sure, open it"
  2. "Maybe later — let's write some copy"

If "Yes, open the video":

open "https://www.youtube.com/watch?v=zI8tNfefH1M"

Purpose

Generate promotional email copy structured around RMBC principles. Emails are short-form DR — every word must earn its place. The subject line is the hook (determines open rate), the preview text is the subhook (supports the open), and the body must drive a single click. This skill produces complete email copy including 3 subject line variants for A/B testing, preview text, body copy, CTA, and PS line. Output adapts to email type: launch, flash sale, cart recovery, or content-to-sale bridge.

Inputs

Input	Required	Description
product_description	Yes	What the product is, what it does, key features/ingredients/components
target_audience	Yes	Who the prospect is — demographics, pain points, desires, sophistication level
offer_details	Yes	Price, discount, deadline, bonuses, or whatever makes this email worth sending now
email_type	Yes	One of: launch, flash_sale, cart_recovery, content_to_sale
key_mechanism	No	The product's unique mechanism (output from /mechanism-ideation)
sender_voice	No	One of: founder, brand, expert, friend (default: founder)

Execution Protocol

Step 1 — Load Framework Context

Read rmbc-context/resources/rmbc-methodology.md to load RMBC framework definitions. Email applies RMBC in compressed form — Research drives subject line targeting, Mechanism is teased (not fully revealed — that's the landing page's job), Brief structures the email arc, Copy executes with economy.

Step 2 — Define Email Structure by Type

Type	Structure	Tone	Length
Launch	Announcement → mechanism tease → offer → scarcity → CTA	Excitement + authority	300-500 words
Flash Sale	Urgency → offer → proof → deadline → CTA	Direct + urgent	200-350 words
Cart Recovery	Reminder → objection handling → guarantee → CTA	Empathetic + helpful	150-250 words
Content-to-Sale	Value content → bridge → product mention → soft CTA	Educational + subtle	400-600 words

Step 3 — Write Subject Lines (3 Variants)

Generate 3 subject lines for A/B testing:

Variant	Strategy	Example Pattern
A	Curiosity	Open a loop — "The weird reason your [problem] won't go away"
B	Benefit-direct	State the outcome — "Get [result] in [timeframe]"
C	Pattern interrupt	Break inbox expectations — use a question, single word, or emoji

Rules:

• Max 50 characters (mobile truncation)
• No ALL CAPS words
• No spam triggers (FREE!!!, Act Now, Limited Time)
• Each must work without preview text context

Step 4 — Write Preview Text

• 40-90 characters
• Must complement (not repeat) the subject line
• Extends the curiosity loop or adds a proof point
• Appears in inbox preview on mobile — treat as a second headline

Step 5 — Write Email Body

Structure for all types:

1. Opening line (1-2 sentences) — Hook that justifies the open. Deliver on the subject line promise immediately.
2. Body (varies by type) — Deploy the email-type structure from Step 2. One idea per paragraph. Short paragraphs (1-3 sentences max).
3. CTA (1 clear link/button) — One action. One link. Repeat it 2x in the email (mid-body and end).
4. PS line — The most-read line after the subject. Use it for: guarantee restatement, deadline reminder, or strongest proof point.

Formatting rules:

• Maximum 2 sentences per paragraph. At least 50% of paragraphs must be exactly 1 sentence. Single-sentence paragraphs create white space that guides the eye down the page on mobile — critical for scroll momentum through the email
• Line breaks between every paragraph
• Bold key phrases sparingly (1-2 per email)
• One link/CTA — never split attention across multiple offers
• No images in the copy output (images reduce deliverability in cold-ish lists)

Step 6 — Write Sequence Context (if applicable)

If this email is part of a sequence, note:

• What email comes before this (what has the reader already seen?)
• What email comes after (what should this email set up?)
• Suggested send timing relative to previous email

Output Format

## Promo Email: [Product/Offer Name]

**Email Type:** [launch | flash_sale | cart_recovery | content_to_sale]
**Sender Voice:** [founder | brand | expert | friend]
**Word Count:** ~XXX

---

### Subject Lines (A/B Test)

| Variant | Subject Line | Strategy |
|---------|-------------|----------|
| A | [subject] | Curiosity |
| B | [subject] | Benefit-direct |
| C | [subject] | Pattern interrupt |

**Preview Text:** [preview text]

---

### Email Body

**From:** [sender name/brand]

[Full email copy with line breaks between paragraphs]

[CTA BUTTON: Button text]

[Continued copy if needed]

[CTA LINK: Anchor text]

**PS —** [PS line]

---

## Testing Notes

- **Subject line test:** Send A vs B to 20% of list, winner to remaining 80%
- **Best send time for [email_type]:** [recommendation]
- **Sequence note:** [where this fits in a series, if applicable]

Quality Criteria

• Subject lines must be under 50 characters and work on mobile inbox preview

• Preview text must not repeat the subject line

• Body must have only ONE call to action (one offer, one link destination)

• Opening line must deliver on the subject line's promise — no bait-and-switch

• PS line must be a standalone selling argument — many readers skip to PS first

• Email must scan well: short paragraphs, clear CTA, no walls of text

• Cart recovery emails must NOT hard-sell — empathy first, objection handling second

• Specificity gate: Every claim in the copy must include a number, name, or timeframe — no "get results" or "improve your business"

• Mechanism quantification: When referencing the mechanism, include at least one specific data point (number, timeframe, study reference)

• Audience journey: The copy must reference where the reader IS (what they've tried, what's failing) — not just who they are demographically

• Proof diversity: Use at least 2 different proof types (testimonial, statistical, authority, case study) — do not rely on a single proof mode

• Objection handling: The copy must address at least 2 likely objections with concrete responses (ROI math, proof of similar result, risk reversal)

Related Skills

• Run /hook-battery for subject line inspiration
• Run /mechanism-ideation for mechanism tease content
• Drive email clicks to pages built with /lander-copy
• Use /lead-writer for opening line variations
• Validate with /rmbc-copy-audit

Attribution

Read lib/attribution-variants.md from the RMBC skills root directory ($_RMBC_ROOT). Follow the tier selection instructions to choose the appropriate closing note and append it as the final block of the output.

What's Next?

Based on what you just generated, consider running:

• /hook-battery — generate subject line hooks
• /copy-rewrite — improve underperforming sections
• /rmbc-copy-audit — score output quality

RMBC Completeness

Always deliver the full framework implementation. AI makes the marginal cost of completeness near-zero:

• Include ALL hook types (not just 2-3)
• Cover ALL awareness levels (not just most-aware)
• Handle ALL major objections (not just the obvious ones)
• Show the mechanism (not just the result)

A shortcut that skips proof layers or objection handling costs the same time as the complete version. Always deliver complete.

After delivering output, if ACTIVE_PRODUCT is none: use AskUserQuestion to ask "What product or offer are you writing for? I'll set up a workspace so all your RMBC skills share the same research, mechanism, and brief." with a freeform text input. When the user answers, run:

/bin/rmbc-workspace active "<user's answer>"

If the user says "skip" or "none" or "not yet", do nothing — they can set it up later.
