What it does
Email Copywriting is an agent skill from revfactory/harness-100. 카피라이터(copywriter)가 사용하는 이메일 카피라이팅 전문 스킬. 제목줄 심리학, 프리헤더 최적화, CTA 설계, 스캔 가능한 본문 구조 등 이메일 매체 특화 작문 방법론을 제공한다. '이메일 카피', '뉴스레터 작성', '제목줄', 'CTA 설계' 등에 활용한다.
Its SKILL.md is about 880 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Writing & Content, covering Copywriting. The licence is Apache-2.0.
When your agent uses it
- Tasks that involve Copywriting
Example prompts
- “CTA 설계”
- “/email-copywriting”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- 첫 문장이 전부다: 열자마자 보이는 1~2문장이 전체 읽기 여부를 결정
- 역피라미드 구조: 가장 중요한 정보를 맨 위에, 부가 정보를 아래로
- 시각적 끊기: 3~4문장마다 소제목, 구분선, 이미지, 인용구 삽입
- 한 문단 = 한 생각: 문단당 2~3문장, 5문장 초과 금지
- 링크 전략: 중요 링크는 본문 상단 1/3에 배치 (스크롤 전 클릭 유도)
What it can do on your machine
Read from SKILL.md and the folder at commit 8e8d35c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Email Copywriting loads about 879 tokens when it runs. Until then it costs about 43 tokens; SKILL.md has 547 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- 카피라이터(copywriter)가 사용하는 이메일 카피라이팅 전문 스킬. 제목줄 심리학, 프리헤더 최적화, CTA 설계, 스캔 가능한 본문 구조 등 이메일 매체 특화 작문 방법론을 제공한다. '이메일 카피', '뉴스레터 작성', '제목줄', 'CTA 설계' 등에 활용한다.
Email Copywriting — 이메일 카피라이팅 전문 방법론
copywriter 에이전트가 뉴스레터를 작성할 때 활용하는, 이메일 매체 고유의 작문 기법.
왜 이메일 카피는 다른가
블로그는 검색으로 유입되고, SNS는 피드에서 발견된다. 이메일은 받은편지함에서 열어야만 읽힌다. 제목줄에서 승부가 갈리고, 열린 후 7초 안에 스크롤할지 닫을지가 결정된다.
제목줄(Subject Line) 설계: CURVE 프레임워크
| 요소 | 설명 | 예시 |
|---|---|---|
| Curiosity | 정보 격차를 만든다 | "대부분의 마케터가 모르는 이메일 비밀" |
| Urgency | 시간적 긴박감 | "오늘 자정까지만 — 이 전략을 공유합니다" |
| Relevance | 독자의 현재 관심사와 연결 | "[AI 트렌드] 이번 주 꼭 알아야 할 3가지" |
| Value | 구체적 이득을 약속 | "읽는 데 3분, 절약하는 시간 3시간" |
| Emotion | 감정을 자극 | "저도 이 실수를 했습니다 (그리고 크게 후회했어요)" |
제목줄 공식 12가지
| # | 공식 | 템플릿 |
|---|---|---|
| 1 | 숫자 + 이익 | "[N]가지 방법으로 [결과]를 달성하세요" |
| 2 | 질문형 | "[독자의 고민]하고 계신가요?" |
| 3 | How-to | "[원하는 결과]하는 법 (전문가 검증)" |
| 4 | 네거티브 | "[실수]를 하고 있다면, 지금 멈추세요" |
| 5 | 소셜 프루프 | "[유명인/기업]이 실제로 사용하는 [도구]" |
| 6 | 대비/반전 | "[통념]이라고요? 정반대입니다" |
| 7 | 개인적 스토리 | "제가 [경험]에서 배운 한 가지" |
| 8 | 뉴스 속보 | "[업계] 판도를 바꿀 소식이 나왔습니다" |
| 9 | 리스티클 예고 | "이번 주 뉴스레터: [주제1], [주제2], 그리고..." |
| 10 | 독점/희소 | "구독자만을 위한 [콘텐츠] 공개" |
| 11 | 도전/도발 | "[결과]를 원한다면, 이 [습관]을 버리세요" |
| 12 | 미완성 루프 | "[상황]이 벌어졌습니다. 결과는..." |
제목줄 최적화 규칙
- 길이: 28~50자 (모바일에서 잘리지 않는 범위)
- 개인화: [이름] 삽입 시 오픈율 평균 26% 향상 (단, 과용 금지)
- 이모지: 1개까지 허용, 2개 이상은 스팸 필터 위험
- 대문자: 전체 대문자 금지, 첫 단어만 대문자 가능
- A/B 변수: 제목줄은 반드시 2개 이상 작성하여 A/B 테스트 설계
프리헤더(Preview Text) 전략
프리헤더는 제목줄의 보조 무기다. 제목줄이 호기심을 유발하면, 프리헤더가 약속을 구체화한다.
| 전략 | 설명 | 예시 |
|---|---|---|
| 보완형 | 제목줄의 정보를 확장 | 제목: "이번 주 AI 뉴스 3선" → 프리헤더: "OpenAI 신모델 + 구글 반격 + 스타트업 잭팟" |
| 후속형 | 제목줄의 문장을 이어감 | 제목: "마케팅 예산을 50% 줄였는데..." → 프리헤더: "매출은 오히려 올랐습니다" |
| CTA형 | 행동을 직접 유도 | 제목: "무료 템플릿 공개" → 프리헤더: "지금 다운로드하세요 (48시간 한정)" |
| 소셜형 | 타인의 반응을 보여줌 | 프리헤더: "지난 호에 127개의 답장이 왔습니다" |
- 길이: 40~90자 (이메일 클라이언트별 다름, Gmail은 90자까지)
- 금지: 제목줄 내용을 그대로 반복하는 것
본문 구조: F-패턴 스캔 설계
이메일 독자는 읽지 않는다, 스캔한다. F자 형태로 시선이 이동한다.

뉴스레터 본문 설계 원칙
- 첫 문장이 전부다: 열자마자 보이는 1~2문장이 전체 읽기 여부를 결정
- 역피라미드 구조: 가장 중요한 정보를 맨 위에, 부가 정보를 아래로
- 시각적 끊기: 3~4문장마다 소제목, 구분선, 이미지, 인용구 삽입
- 한 문단 = 한 생각: 문단당 2~3문장, 5문장 초과 금지
- 링크 전략: 중요 링크는 본문 상단 1/3에 배치 (스크롤 전 클릭 유도)
섹션별 권장 구조
[인트로: 1~2문장 — 이번 호의 핵심 메시지]
---
[메인 스토리: 가장 중요한 콘텐츠]
- 소제목
- 본문 (5~8문장)
- CTA 버튼 또는 링크
---
[서브 스토리 2~3개: 짧은 큐레이션]
- 각 항목 2~3문장 + 링크
---
[추천 리소스 / 도구 / 도서]
---
[클로징: 독자에게 질문 또는 다음 호 예고]CTA(Call-to-Action) 설계
CTA 배치 전략
| 위치 | CTA 유형 | 전환율 기대치 |
|---|---|---|
| 상단 (첫 200px) | 핵심 CTA — 이번 호의 메인 액션 | 가장 높음 |
| 중단 (메인 스토리 후) | 보조 CTA — 관련 콘텐츠 탐색 | 중간 |
| 하단 (클로징) | 반복 CTA — 상단과 동일하거나 공유 유도 | 보험 역할 |
CTA 문구 공식
- 동사로 시작: "읽어보기", "다운로드하기", "지금 확인하기"
- 구체적 이익 포함: "5분 가이드 읽기" > "자세히 보기"
- 버튼 디자인: 텍스트 링크보다 버튼이 CTR 28% 높음
- 긴급성 부여: "48시간 한정", "선착순 100명"
톤앤보이스 매트릭스
| 뉴스레터 유형 | 권장 톤 | 1인칭 | 독자 호칭 | 이모지 사용 |
|---|---|---|---|---|
| 비즈니스/산업 | 전문적 + 위트 | "저는/우리는" | "여러분" | 최소 (섹션 구분용) |
| 테크/개발 | 캐주얼 + 실용적 | "저는" | "여러분/당신" | 자유롭게 |
| 라이프스타일 | 친밀 + 감성적 | "나는" | "당신" | 적극적 |
| 큐레이션/뉴스 | 객관적 + 간결 | "편집팀" | "독자 여러분" | 거의 없음 |
A/B 테스트 변수 우선순위
효과가 큰 순서대로 테스트한다 (한 번에 1개 변수만):
- 제목줄 (오픈율에 직접 영향, 가장 먼저 테스트)
- 발송 시간 (요일+시간대)
- CTA 문구/디자인 (클릭률)
- 본문 길이 (긴 형태 vs 짧은 형태)
- 프리헤더 (오픈율 미세 조정)
- 발신자 이름 (브랜드명 vs 개인 이름)
