# Email Creative Builder

Writes and iterates a single email creative — subject-line variants + preheader, body copy, one clear CTA, and a plain-text alternate — each message-matched to the destination landing page and traced to approved claim wording. This is the build skill that produces the SEND **E/D** unit (the email analog of paid's ad-creative-builder). It does not score the email, run the D1 veto, or compute the EQS — that is `email-quality-auditor` — and it does not design the multi-step flow (`email-sequence-designer`) or the test (`send-experiment-designer`).

**Scope guard**: this skill builds the creative unit + message-match + claim flags only. It drafts subject-line variants for the creative but does **not** pre-score or rank them (spam-trigger flags, length/truncation, emoji-count, inbox-preview render) — that is [subject-line-lab](../subject-line-lab/SKILL.md). It scores no SEND dimension, runs no veto, and does not compute the profile-weighted EQS — [email-quality-auditor](../../deliver/email-quality-auditor/SKILL.md) owns all four vetoes (S1/S2/N1/D1) and the EQS rollup.

## Quick Start

```
Write 5 subject lines + preheader + body + CTA for [offer], destination [URL], promo mode
```

```
Draft a cold-outbound email to [persona] for [offer]; personalize on [signal]; destination [URL]
```

```
Iterate these losing subject lines: [p

# Email Creative Modes (SEND-E/D)

Three use-case pattern sets for `email-creative-builder`. Pick the mode that matches the program; the skill stays use-case-agnostic and the mode only changes the pattern, not the contract. All three end at the same **message-match map** so [email-quality-auditor](../../../deliver/email-quality-auditor/SKILL.md) can score the E/D unit and run the D1 claim veto.

## Mode A — Promotional / lifecycle (B2C)

- **Goal**: one action (buy, redeem, book). Single dominant CTA.
- **Structure**: hook → value/offer → proof (review, stat, guarantee) → CTA → urgency (honest deadline/stock only).
- **Offer**: pull terms + promo code + expiry from the live-offers table ([offer-claims-registry](../../../../protocol/offer-claims-registry/SKILL.md), `memory/claims/offers.md`) — never invent them.
- **Claims**: every product/benefit claim traces to an approved row in `memory/claims/claims-ledger.md`; unregistered → `[needs source]` → `memory/events/claims.ndjson` via an authorized `operation: propose` request to `registry-events.py`.

## Mode B — Cold outbound (B2B)

- **Goal**: a reply, not a click. One low-friction ask (interest-check / soft CTA).
- **Structure**: relevance line (why them, now) → one concrete value point → light social proof → single soft ask. Keep it short; plain-text feel.
- **Personalization**: one genuine, verifiable personalization token per message; no fabricated "I saw you…" specifics.
- **Compliance**: physical mailing address + a functioning opt-out honored within 10 business days (CAN-SPAM); the one-click `List-Unsubscribe` header is a Gmail/Yahoo bulk-sender rule (RFC 8058), not a CAN-SPAM statute. Consent/lawful-basis per recipient from [consent-registry](../../../../protocol/consent-registry/SKILL.md). Spintax/variants must not degrade into misleading claims.

## Mode C — Newsletter / creator

- **Goal**: sustained engagement + (where relevant) monetization. CTA may be read/forward/refer, not buy.
- **Structure**: subject promise → lead → 1–3 sections → clearly-labeled sponsorship (if any) → forward/refer ask.
- **Sponsorship = ad**: any paid placement gets an explicit disclosure; the offer/claim still routes through the claims ledger (D1). Monetization economics belong to [newsletter-monetization-planner](../../../nurture/newsletter-monetization-planner/SKILL.md).

## Message-match map (all modes — required output)

For each CTA, record the row so the auditor can verify email↔landing consistency:

| Email element | Says | Landing page must show | Match? |
|---|---|---|---|
| Subject/hook | <promise> | <same promise above the fold> | ✓ / ✗ |
| Offer | <terms/code> | <identical terms/code> | ✓ / ✗ |
| CTA label | <verb + object> | <same next step> | ✓ / ✗ |

A mismatch is a message-match failure (SEND-`D` sub-item) — flag it; the post-click fix is [landing-optimizer](../../../../influencer/report/landing-optimizer/SKILL.md).

# Subject Line & Preheader Specs

Render limits and variant-labeling for `email-creative-builder`, so the subjects it drafts carry cleanly into [send-experiment-designer](../../../deliver/send-experiment-designer/SKILL.md). Numbers are practical inbox-render limits, not hard protocol limits — treat them as guidance labeled Estimated.

## Render limits (characters before truncation)

| Surface | Desktop | Mobile | Guidance |
|---|---|---|---|
| **Subject line** | ~60 | ~30–40 | Front-load the promise in the first ~30 chars; mobile truncates hardest |
| **Preheader** | ~90–110 | ~40–50 | Extends (never repeats) the subject; set it explicitly or the client pulls body text |
| **From name** | ~20 | ~20 | Recognizable sender; consistency drives opens |

## Variant set (draft 3–5, one angle each)

Label each variant so it maps to a test cell:

| Angle | Pattern | Example shape |
|---|---|---|
| Curiosity | open loop, withhold | "The one thing we changed…" |
| Benefit | lead with outcome | "Cut your setup time in half" |
| Offer | lead with the deal (promo mode) | "24 hours: 20% off everything" |
| Personalization | genuine, verifiable token | "{first_name}, your {plan} renews soon" |
| Question | provoke a mental yes | "Still exporting reports by hand?" |

## Rules

- **One variable per test cell** — if testing subjects, hold preheader/creative/send-time constant (isolation is enforced by [send-experiment-designer](../../../deliver/send-experiment-designer/SKILL.md)).
- No spam-trigger patterns: no ALL-CAPS, no `!!!`, no misleading "RE:"/"FWD:" fakery, no false scarcity. These also fail the [deliverability-qa](../../../setup/deliverability-qa/SKILL.md) spam-content scan.
- Emoji: at most one, only if on-brand; never in cold-outbound (B2B) subjects.
- Label the output so each subject+preheader pair carries a stable variant id (`SUBJ-A`, `SUBJ-B`, …) into the test.

skill-card.md

## Description:

Drafts a single email creative with subject-line variants, preheader, body copy, one primary CTA, plain-text alternate, and message-match notes tied to the destination page and approved claims.

This skill is ready for commercial/non-commercial use.

## Publisher:

[aaron-he-zhu](https://clawhub.ai/user/aaron-he-zhu)

### License/Terms of Use:

MIT-0

## Use Case:

Marketing operators and agents use this skill to draft or iterate one email creative for promotional, cold-outbound, or newsletter workflows. It helps keep copy aligned to the destination page, approved claim wording, and a follow-on testing or audit handoff.

### Deployment Geography for Use:

Global

## Known Risks and Mitigations:

Risk: Drafted email copy can include unsupported marketing claims when approved claim data or destination evidence is missing.

Mitigation: Keep unresolved claims visibly marked, require claim and destination review before sending, and use the separate audit workflow for scoring or veto decisions.

Risk: Campaign inputs, consent state, or personalization signals may include sensitive customer or recipient context.

Mitigation: Provide only the materials needed for the drafting task and review saved drafts or proposed claim events before reusing them elsewhere.

Risk: The skill produces creative drafts but does not perform email sending or suppression checks.

Mitigation: Require separate send approval and replay-safe consent or suppression verification before any campaign is sent.
