Gathering Requirements

需求收集

Before creating any sequence, collect these inputs:
  1. Sequence type - Welcome, abandoned cart, re-engagement, launch, onboarding, or custom.
  2. Product/service - What is being sold or promoted?
  3. Target audience - Who receives this sequence? Segment details.
  4. Primary goal - Convert, activate, retain, re-engage, upsell?
  5. Sender - Who is the "from" name and email? (Founder, brand, team member)
  6. Tone - Friendly, professional, urgent, educational, witty.
  7. ESP - What email platform? (Affects merge tags and HTML capabilities.)
  8. Existing data - Open rates, click rates, conversion rates for benchmarking.
在创建任何序列之前，请收集以下信息：
  1. 序列类型 - 欢迎、购物车遗弃召回、重新激活、产品发布、新用户引导或自定义类型。
  2. 产品/服务 - 销售或推广的是什么？
  3. 目标受众 - 谁会收到这个序列？请提供细分详情。
  4. 核心目标 - 转化、激活、留存、重新激活、追加销售？
  5. 发件人 - 发件人名称和邮箱是什么？（创始人、品牌、团队成员）
  6. 语气 - 友好、专业、紧迫、教育性、诙谐。
  7. ESP - 使用什么邮件平台？（会影响合并标签和HTML功能）
  8. 现有数据 - 用于基准对比的打开率、点击率、转化率。

Universal Email Principles

通用邮件原则

Subject Line Rules

主题行规则

  • Keep between 30-50 characters (6-10 words).
  • Front-load the most important word.
  • Use lowercase for a casual feel, title case for professional.
  • Never use ALL CAPS for the full subject line.
  • Include personalization (first name) sparingly, not in every email.
  • A/B test every subject line in your ESP.
  • 长度控制在30-50个字符（6-10个单词）。
  • 将最重要的词放在开头。
  • 非正式风格用小写，专业风格用标题大小写。
  • 主题行切勿全部使用大写字母。
  • 谨慎使用个性化内容（如名字），不要每封邮件都加。
  • 在ESP中对每个主题行进行A/B测试。

Preview Text Rules

预览文本规则

  • Always write custom preview text (40-90 characters).
  • Do not repeat the subject line.
  • Complement the subject line by adding context or intrigue.
  • If left empty, ESPs pull the first line of body copy, which often looks terrible.
  • 务必编写自定义预览文本（40-90个字符）。
  • 不要重复主题行内容。
  • 通过补充上下文或制造悬念来配合主题行。
  • 如果留空，ESP会提取正文第一行内容，通常效果很差。

Email Structure

邮件结构

  1. Hook (first 2 lines) - Must earn the scroll. Ask a question, state a bold claim, or reference something personal.
  2. Body (3-8 sentences) - One idea per email. Do not try to cover everything.
  3. CTA (1 primary) - One clear action. Link it 2-3 times in the body.
  4. PS line (optional) - Second-most-read part of an email. Use for urgency or bonus info.
  1. 钩子（前2行） - 必须吸引用户继续滚动。可以提问题、做出大胆声明，或者引用个性化内容。
  2. 正文（3-8句话） - 每封邮件只聚焦一个核心观点，不要试图面面俱到。
  3. CTA（1个主按钮） - 一个清晰的行动指令。在正文中链接2-3次。
  4. PS行（可选） - 邮件中第二受关注的部分。用于制造紧迫感或提供额外信息。

Segmentation Rules

细分规则

Segment sequences based on:
  • Behavior - Pages visited, features used, emails opened, links clicked.
  • Demographics - Industry, company size, role, location.
  • Lifecycle stage - New lead, trial user, paying customer, churned user.
  • Engagement level - Active (opened in 30 days), Inactive (no opens in 60+ days).
  • Source - How did they enter the sequence? Organic, paid, referral, event.
根据以下维度对序列进行细分：
  • 行为 - 访问的页面、使用的功能、打开的邮件、点击的链接。
  • 人口统计 - 行业、公司规模、职位、地理位置。
  • 生命周期阶段 - 新潜在客户、试用用户、付费客户、流失用户。
  • 参与度 - 活跃用户（30天内打开过邮件）、不活跃用户（60天以上未打开邮件）。
  • 来源 - 用户如何进入序列？自然流量、付费流量、推荐、活动。

Spam Trigger Avoidance

避免垃圾邮件触发词

Avoid these in subject lines and body:
  • ALL CAPS words (e.g., "FREE", "BUY NOW", "CLICK HERE")
  • Excessive exclamation marks (!!!)
  • Spam trigger phrases: "Act now", "Limited time", "You've been selected", "Congratulations", "No obligation", "100% free", "Click below", "Dear friend"
  • Too many images with too little text (maintain 60/40 text-to-image ratio)
  • Deceptive subject lines (Re:, Fwd: when not actually a reply/forward)
  • Purchased lists (always use opt-in subscribers only)
主题行和正文中避免以下内容：
  • 全大写单词（如"FREE"、"BUY NOW"、"CLICK HERE"）
  • 过多感叹号（!!!）
  • 垃圾邮件触发短语："Act now"、"Limited time"、"You've been selected"、"Congratulations"、"No obligation"、"100% free"、"Click below"、"Dear friend"
  • 图片过多文字过少（保持60/40的文图比例）
  • 欺骗性主题行（非回复/转发却使用Re:、Fwd:）
  • 购买的邮件列表（始终仅使用选择加入的订阅者）

HTML Email Template Guidelines

HTML邮件模板指南

When the user requests HTML email templates:
  1. Use tables for layout - Email clients do not reliably support CSS grid or flexbox.
  2. Inline all CSS - Many email clients strip 
    <style>
    blocks.
  3. Max width: 600px - Standard email width for cross-client compatibility.
  4. Use web-safe fonts - Arial, Helvetica, Georgia, Times New Roman.
  5. Include alt text on all images - Many readers have images disabled.
  6. Test in multiple clients - Gmail, Outlook, Apple Mail, Yahoo at minimum.
  7. Mobile-first - 60%+ of emails are opened on mobile. Stack columns on small screens.
  8. Include a plain-text version - Always provide a text fallback for deliverability.
当用户请求HTML邮件模板时：
  1. 使用表格布局 - 邮件客户端对CSS grid或flexbox的支持不可靠。
  2. 内联所有CSS - 许多邮件客户端会移除
    <style>
    块。
  3. 最大宽度600px - 跨客户端兼容的标准邮件宽度。
  4. 使用网络安全字体 - Arial、Helvetica、Georgia、Times New Roman。
  5. 为所有图片添加alt文本 - 许多读者禁用图片显示。
  6. 在多个客户端测试 - 至少测试Gmail、Outlook、Apple Mail、Yahoo。
  7. 移动优先 - 60%以上的邮件在移动设备上打开，小屏幕上堆叠列布局。
  8. 包含纯文本版本 - 始终提供文本备份以确保送达率。

Sending Emails via Resend API

通过Resend API发送邮件

This skill can send emails directly using the Resend API. This is optional: if the API key is not configured, the skill will still generate email content as usual without sending.
本技能可直接使用Resend API发送邮件，此功能为可选：如果未配置API密钥，技能仍会正常生成邮件内容但不会发送。

Prerequisites

前提条件

The 
RESEND_API_KEY
environment variable must be set. Check for it by running:
bash
source ~/.claude/.env.global 2>/dev/null
if [ -z "$RESEND_API_KEY" ]; then
  echo "RESEND_API_KEY is not set. Emails will be generated but not sent."
  echo "To enable sending, add RESEND_API_KEY to ~/.claude/.env.global"
else
  echo "RESEND_API_KEY is configured. Ready to send emails."
fi
必须设置
RESEND_API_KEY
环境变量。通过以下命令检查：
bash
source ~/.claude/.env.global 2>/dev/null
if [ -z "$RESEND_API_KEY" ]; then
  echo "RESEND_API_KEY is not set. Emails will be generated but not sent."
  echo "To enable sending, add RESEND_API_KEY to ~/.claude/.env.global"
else
  echo "RESEND_API_KEY is configured. Ready to send emails."
fi

Sending a Single Email

发送单封邮件

Use the Resend 
/emails
endpoint to send an individual email from the sequence:
bash
source ~/.claude/.env.global 2>/dev/null
curl -X POST https://api.resend.com/emails \
  -H "Authorization: Bearer ${RESEND_API_KEY}" \
  -H "Content-Type: application/json" \
  -d '{
    "from": "Your Name <you@yourdomain.com>",
    "to": ["recipient@example.com"],
    "subject": "Subject line here",
    "html": "<p>Email body here</p>"
  }'
The response returns a JSON object with an 
id
field for tracking. Replace the 
from
, 
to
, 
subject
, and 
html
fields with the actual values from the generated sequence.
使用Resend的
/emails
端点发送序列中的单封邮件：
bash
source ~/.claude/.env.global 2>/dev/null
curl -X POST https://api.resend.com/emails \
  -H "Authorization: Bearer ${RESEND_API_KEY}" \
  -H "Content-Type: application/json" \
  -d '{
    "from": "Your Name <you@yourdomain.com>",
    "to": ["recipient@example.com"],
    "subject": "Subject line here",
    "html": "<p>Email body here</p>"
  }'
响应会返回包含
id
字段的JSON对象用于追踪。将
from
、
to
、
subject
和
html
字段替换为生成序列中的实际值。

Sending a Batch (Full Sequence)

批量发送（完整序列）

To send multiple emails from a sequence at once, use the batch endpoint. This is useful for sending the same email to multiple recipients or sending several sequence emails simultaneously:
bash
source ~/.claude/.env.global 2>/dev/null
curl -X POST https://api.resend.com/emails/batch \
  -H "Authorization: Bearer ${RESEND_API_KEY}" \
  -H "Content-Type: application/json" \
  -d '{
    "emails": [
      {
        "from": "Your Name <you@yourdomain.com>",
        "to": ["recipient1@example.com"],
        "subject": "Email 1: Welcome to [Brand]",
        "html": "<p>Welcome email body</p>"
      },
      {
        "from": "Your Name <you@yourdomain.com>",
        "to": ["recipient2@example.com"],
        "subject": "Email 1: Welcome to [Brand]",
        "html": "<p>Welcome email body</p>"
      }
    ]
  }'
要一次性发送序列中的多封邮件，使用批量端点。这适用于向多个收件人发送同一封邮件，或同时发送多封序列邮件：
bash
source ~/.claude/.env.global 2>/dev/null
curl -X POST https://api.resend.com/emails/batch \
  -H "Authorization: Bearer ${RESEND_API_KEY}" \
  -H "Content-Type: application/json" \
  -d '{
    "emails": [
      {
        "from": "Your Name <you@yourdomain.com>",
        "to": ["recipient1@example.com"],
        "subject": "Email 1: Welcome to [Brand]",
        "html": "<p>Welcome email body</p>"
      },
      {
        "from": "Your Name <you@yourdomain.com>",
        "to": ["recipient2@example.com"],
        "subject": "Email 1: Welcome to [Brand]",
        "html": "<p>Welcome email body</p>"
      }
    ]
  }'

Important Notes

重要提示

  • Domain verification required: The 
    from
    address domain must be verified in your Resend account. If you have not verified a domain, Resend provides a shared 
    onboarding@resend.dev
    address for testing.
  • Rate limits: Resend has rate limits depending on your plan. For large sequences, add a short delay between batch calls.
  • No RESEND_API_KEY? The skill works without it. All email content (subject lines, body copy, preview text, timing) is generated normally. The Resend integration simply adds the ability to send the generated emails directly from the CLI.
  • 需验证域名 - 
    from
    地址的域名必须在您的Resend账户中验证。如果未验证域名，Resend提供共享的
    onboarding@resend.dev
    地址用于测试。
  • 速率限制 - Resend根据您的套餐设置速率限制。对于大型序列，在批量调用之间添加短暂延迟。
  • 无RESEND_API_KEY？ 技能仍可正常工作，所有邮件内容（主题行、正文、预览文本、发送时机）都会正常生成。Resend集成仅添加从CLI直接发送生成邮件的功能。
