多语言查询

目标市场非英语时，必须生成当地语言版本的 query：

• 西班牙语市场（拉美/西班牙）：{product} distribuidor {country} / {product} mayorista {country}
• 阿拉伯语市场（中东）：{product} موزع {country} / {product} مستورد {country}
• 德语市场（DACH）：{product} Händler {country} / {product} Großhändler {country}
• 法语市场：{product} distributeur {country} / {product} grossiste {country}
• 俄语市场：{product} дистрибьютор {country} / {product} оптовый {country}
• 葡语市场（巴西/葡萄牙）：{product} distribuidor {country} / {product} atacadista {country}

输出格式

## 🔍 三通道搜索结果

### 通道分布
| 通道 | 原始结果 | 去重后 | 通过黑名单 |
|------|---------|--------|------------|
| A: Google Maps | N1 | N1' | N1'' |
| B: Google Search | N2 | N2' | N2'' |
| C: FB/LinkedIn | N3 | N3' | N3'' |
**最终候选**：N 家

### TOP 10 候选客户
| # | 公司名 | 官网 | 国家 | 通道 | 邮箱 | LinkedIn | 电话 |
|---|--------|------|------|------|------|----------|------|
| 1 | ... | ... | ... | A+B+C | ... | ... | ... |

STOP RULE

• 单次搜索总轮次上限 15 轮（每通道 5 轮）
• 达到上限或候选数 ≥ 30 家即停止
• 候选数 < 5 家时告知用户「信号不足，建议换关键词或扩大市场范围」

3. 按以下格式返回：
   • 客户分类：高价值（A）/ 中等（B）/ 潜力（C）
   • 具体行动建议：第一步做什么、第二步做什么
   • 开发信/邮件模板（个性化，以客户痛点开头，非产品广告）
   • 跟进时间表：Day1 / Day3 / Day7 / Day14

如果用户没有明确说明产品或市场，请先询问这两个关键信息。

邮件主题行优化（提升打开率）

邮件主题行决定 70%+ 的打开率。每次生成开发信时，同时提供 3-5 个主题行变体，使用不同策略：

• Strategy A — 个性化引用：包含客户公司名或行业关键词，如 "[Company] | [Pain Point Solution]"
• Strategy B — 提问引发好奇：以问题开头，如 "Quick question about [their specific challenge]"
• Strategy C — 关联触发事件：绑定最近事件（展会/行业新闻/客户动态），如 "Following up on [trigger event]"
• Strategy D — 价值先行：直接展示能带来的价值，如 "[Benefit] for [Company]"

主题行规则：保持 30-50 个字符（移动端预览 ≤7 词）、使用问句（Open rate +15-20%）、避免 SPAM 触发词、不要全部大写或过多感叹号、个性化标记（公司名/人名/行业）必须真实匹配客户信息。

多语言邮件生成

当客户目标市场为非英语国家时，生成多语言邮件版本：

• 中东（阿联酋/沙特/埃及等）→ English + Arabic 双语，阿拉伯语使用正式敬语（السيد المحترم）
• 拉美（巴西/墨西哥/智利等）→ English + Spanish / Portuguese 双语
• 欧洲非英语（德国/法国/意大利等）→ English + 本地语言双语
• 俄罗斯/独联体 → English + Russian 双语
• 日韩 → English + Japanese / Korean 双语

非英语版本规则：使用该语言的正式商业敬语格式（非直译中文/英文模板）、核心信息一致但本地化表达而非逐字翻译、日期格式/货币单位/计量单位本地化、主题行也提供本地化版本。始终以英语版本为主要版本，本地化版本为第二版本。如客户市场信息不明确，默认只生成英语版本。

4. 【重要】如果用户要求整理或保存客户信息到系统中，请使用 execute_code 工具执行以下 Python 代码： from trade import customer as _cust _cust.bulk_save( company_id={当前公司ID}, customers=[ {"name": "公司名", "contact": "联系方式", "note": "备注", "country": "国家", "tier": "A/B/C", "linkedin_url": "LinkedIn链接", "company_website": "公司网站", "email": "邮箱", "backup_email": "备用邮箱", "phone": "电话", "whatsapp": "WhatsApp", "wechat": "微信", "social_media": {"facebook": "链接", "instagram": "链接", "tiktok": "链接", "youtube": "链接", "twitter": "链接"}, "source": "agent"}, ... ], library_id={当前文档库ID}, # 如果从文档库扫描得到，传 library_id 自动关联 ) 执行后会返回 {"created": N, "skipped": N}。请告知用户保存结果。 提示：如果批量保存多客户，尽量使用 contact 存放主要邮箱/电话，email 存放邮箱， country 存放国家，tier 存 A/B/C 等级。source 填 "agent"。

按目标市场定制开发信策略

不同地区的买家对沟通方式的偏好不同。生成开发信/回复/报价时，根据客户所在国家/地区调整语气和内容侧重。

北美（美国/加拿大）

• 语气：直截了当、结果导向
• 侧重：时效性、成本节约、ROI 数据
• Hook：以行业数据或客户痛点开场
• 格式：短段落、破折号列表、清晰 CTA

欧洲（德国/法国/英国/北欧）

• 语气：专业、正式、细节导向
• 侧重：品质认证（CE/ISO/TUV）、技术参数、供应链稳定性
• Hook：以认证资质或技术指标开场

中东（海湾国家/沙特/阿联酋）

• 语气：关系导向、尊重/礼貌
• 侧重：低价、详细产品描述、售后服务
• Hook：以对当地市场的了解或合作经历开场

南美（巴西/墨西哥/阿根廷）

• 语气：友好、耐心、简单英语
• 侧重：免费样品、OEM/ODM 能力、灵活 MOQ
• Hook：以免费样品或定制能力开场

澳洲/新西兰

• 语气：直接、友好、非正式
• 侧重：交期、性价比、服务响应

东南亚

• 语气：礼貌、灵活、关系建立
• 侧重：价格竞争力、付款条件灵活性、交期

报价与谈判 6 策略

当用户需要进行价格谈判时，根据客户反应选择合适的策略。不要只降价格，要转换谈判维度。

1. 话题转移型 -- 客户说贵，不正面应战，转移话题到其他维度
2. 价值主导型 -- 强调差异化价值而非价格
3. 间接让步型 -- 不降显性价格，在其他方面让步（打样/质保/运费）
4. 直接让步型 -- 小幅降价但换回条件（如提高订单量）
5. 客户背书型 -- 引用类似客户成交数据
6. 二选一型 -- 给客户两个选择，引导到期望方案

失联客户重新接触 4 策略

当客户在报价/样品/谈判阶段突然失联时，根据不同时间间隔选择策略。

1. 直接询问型（失联 3-7 天）
2. 业务角度型（失联 1-2 周）：提供新的行业信息或市场变化
3. 朋友角度型（失联 2-4 周）：以节日问候/出差为由重新接触
4. 解决方案列表型（失联 1 个月以上）：逐条回应客户可能关心的问题

发送前强制自检

每次生成任何邮件、报价、回复后，在输出给用户之前，必须对照文末「Quality Gate Checklist」逐项检查。这是强制步骤，不得跳过。漏掉一项意味着可能丢失客户。

Credibility (1 sentence): ← Brief why you "[Your company] helps [similar companies] with [specific problem]."

### Regional Language Quick Reference

| Region | Language | Subject Tone | Formal Greeting |
|--------|----------|-------------|-----------------|

## Common Pitfalls

1. **Product-first mentality** 🔴 **最致命**: 开发信第一句就介绍公司和产品。正确做法：先谈客户的难处 → 你能怎么帮 → 最后才一句话带过产品
2. **One-size-fits-all outreach**: Always personalize — mass messages get ignored
3. **Giving up too early**: 80% of customers are closed after the 4th follow-up
4. **空洞话术**: 不说"质量好价格优服务好"，具体说"每批货附 X 项检测数据""从下单到出货最快 Y 天""欧美 CE/FDA 认证我们在行"
5. **Ignoring time zones**: Respect the prospect's working hours
6. **Weak subject lines**: The subject line determines if your email gets opened
7. **No clear CTA**: Always tell the prospect what to do next
8. **Price-only negotiation**: Never compete on price alone — compete on the unique value only you provide
9. **Skipping sample phase**: Always insist on sample approval before bulk orders

## 反营销腔自检（生成后强制执行）

> 每封开发信生成后、输出给用户前，必须对照以下清单逐项检查。任何一项 fail 必须重写后再检查，不得跳过。

### 禁用词清单（命中即重写）

| 类别 | 禁用表达 | 替换为 |
|------|---------|--------|
| 空洞话术 | "质量好价格优服务好" | "每批货附 X 项检测数据 / 从下单到出货最快 Y 天 / 欧美 CE/FDA 认证我们在行" |
| 营销硬卖 | "Best price / Lowest price / Best quality" | 具体数据 + 对比锚点（如 "MOQ 200 vs 行业 500"）|
| 催促话术 | "Act now / Limited time / Don't miss out" | 客观时间窗口（如 "我们的 Q3 产能还剩 30%"）|
| 自吹自擂 | "We are the leading / We are the best" | 客户背书（如 "X 公司用我们 3 年了，复购率 85%"）|
| 模糊承诺 | "We can do anything / We support everything" | 明确边界（如 "我们做 X 不做 Y，因为 X 才是我们的强项"）|

### 反营销腔语气校验

读一遍开发信，问自己 5 个问题：

1. **第一句是在讲客户还是在讲自己？** — 必须是客户（"I noticed your..."）而非自己（"We are..."）
2. **60% 篇幅在讲客户痛点还是在讲产品？** — 必须客户痛点为主
3. **有没有具体到这个客户独有的细节？** — 必须有（客户网站/动态/产品线某一项）
4. **删掉公司名后这封信是否适用任何同行？** — 如果适用则失败（说明太泛）
5. **客户 5 秒内能否感受到"这封信和我有关"？** — 不能则重写

### 反垃圾邮件规则（避免进垃圾箱）

**主题行**：
- [ ] 不含 SPAM 触发词：FREE / GUARANTEED / 100% / WINNER / URGENT / ACT NOW / LIMITED TIME / NO OBLIGATION
- [ ] 不全大写（如 "BUY NOW" → "Buy now"）
- [ ] 不含过多感叹号（最多 1 个）
- [ ] 字符数 30-50（移动端 5-7 词预览）
- [ ] 不含过多特殊符号（$$$ / !!! / ???）

**正文**：
- [ ] 大写单词 ≤1 个（专有名词除外）
- [ ] 红色字体强调 ≤2 处
- [ ] 图片面积 < 总面积 50%
- [ ] 包含退订方式（"Reply STOP to unsubscribe"）
- [ ] 附件 < 10MB
- [ ] 收件人非 role email（info@/sales@/contact@ 提醒用户尝试找具体人名）
- [ ] HTML 邮件必须同时带纯文本版本（multipart/alternative）
- [ ] 字体使用 web-safe（Arial / Helvetica / Georgia）

## 替换法 A/B 测试（每封开发信强制）

> 同一客户生成 2 个正文变体，择优发送。这不是可选项 — 99% 的开发信死于「我以为这封好」。

### 变体生成规则

对同一背调结果，生成 2 个变体：

- **变体 A — 痛点先行型**：开头 1-2 句直接戳客户最可能的痛点，再用 2-3 个 bullet 给方案，最后 1 句 CTA
- **变体 B — 价值先行型**：开头 1-2 句展示能给客户带来的具体价值（数字化），再用 1-2 个证据支撑，最后 1 句 CTA

两个变体必须：
- 基于同一背调结果（不能 A 用一套信息 B 用另一套）
- 主题行不同（A 用策略 A 个性化引用，B 用策略 B 提问引发好奇）
- CTA 相同（避免测试变量太多）
- 字数差异 ≤20%

### 选择规则

默认推荐变体 A（痛点先行），原因：外贸买家痛点驱动 > 价值驱动。
但以下场景选变体 B：
- 客户是连锁超市 / 大品牌（已被各种供应商围着转，痛点信太多，价值信反而新鲜）
- 客户在 LinkedIn 上发过招聘 / 扩张信号（说明有预算，直接给价值更直接）
- 客户是 trading company / middleman（他们关心的是「你能帮我赚多少」而非「你能解决我什么痛」）

### 输出格式

━━━ 变体 A — 痛点先行 ━━━ 主题：[Subject A] 正文： [Body A]

━━━ 变体 B — 价值先行 ━━━ 主题：[Subject B] 正文： [Body B]

━━━ 推荐 ━━━ 推荐变体 [A/B]，原因：[基于客户类型判断]

⚠️ 反营销腔自检：[PASS/FAIL] ⚠️ 反垃圾邮件自检：[PASS/FAIL]
