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.

| 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 |
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 |

## Promo Email: [Product/Offer Name]

[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]
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)
