Purpose & Capability
The name/description (newsletter growth, content optimization, A/B testing, analytics) matches the included files and examples. The code modules (subscriber acquisition, content optimizer, analytics, main) implement the documented features and there are no unexpected binaries or cloud credentials requested.
Instruction Scope
SKILL.md instructs running the local Python scripts and shows examples of reading exported CSVs and pasting content. The runtime instructions focus on local analysis and do not direct the agent to read unrelated system files, harvest environment variables, or transmit data to third‑party endpoints. Examples that mention ESP exports are reasonable for the stated purpose.
Install Mechanism
There is no install spec; this is an instruction/package with source files. All Python code uses the standard library in the visible files and requirements.txt contains only commented optional dependencies. No downloads, archives, or external installers are referenced.
Credentials
The skill declares no required environment variables, no primary credential, and no config paths. The code shown does not access environment variables or secret stores. This is proportional for a local analysis tool.
Persistence & Privilege
Flags show always:false and normal user-invocable/autonomous invocation defaults. The skill does not request persistent system-level privileges or modify other skills' configs in the provided materials.
Assessment
This package appears coherent and safe for local use: it runs Python scripts that analyze text and numeric campaign data and does not request secrets or perform network calls in the provided files. Before installing or running: 1) review the omitted/truncated portions (subscriber_acquisition and any remaining files) to ensure there are no hidden network sends or credential usages; 2) if you plan to connect it to an ESP or automate imports, expect those integrations to require API keys—verify where and how you supply them; 3) treat any subscriber data (emails, names) as sensitive—run the tool in a secure environment and avoid pasting production PII into unfamiliar tooling; 4) if you will publish or deploy this tool, run it in a sandbox first and consider adding unit tests and input validation for robustness.

Like a lobster shell, security has layers — review code before you run it.

Newsletter Growth Hacker

专业的邮件通讯(Newsletter)增长黑客工具,整合订阅者获取、内容优化、A/B 测试和数据分析四大核心功能。

快速开始

cd skills/newsletter-growth-hacker/scripts
python main.py

核心功能

1. 订阅者获取策略

提供 6 大类经过验证的订阅者获取策略:

策略转化率投入ROI
内容升级策略3-8%中等
社会证明策略2-5%中高
推荐计划15-25%非常高
交叉推广5-12%中等
SEO 引流磁铁2-6%高(前期)长期非常高
付费广告1-4%中等取决于 CPC

使用场景

  • 制定订阅者增长计划
  • 选择适合预算和资源的获取渠道
  • 预测不同策略的增长效果

示例

from subscriber_acquisition import SubscriberAcquisition

acquisition = SubscriberAcquisition()

# 获取所有策略
strategies = acquisition.get_strategies()

# 计算增长预测
projection = acquisition.calculate_projection(
    current_subscribers=1000,
    strategy="referral_program",
    months=6
)
# 输出:6 个月后订阅者数量、总增长、月增长率

2. 内容优化建议

基于邮件营销最佳实践的内容分析和优化建议。

分析维度

  • 内容长度和段落结构
  • 可读性评分
  • 主题行检测
  • CTA(行动号召)检测
  • 移动友好度

优化原则

  1. 价值先行 - 开篇展示核心价值
  2. 可扫描性 - 小标题、短段落、列表
  3. 个性化 - 细分受众、个人故事
  4. 行动导向 - 单一清晰 CTA
  5. 移动优先 - 单栏布局、大字体

使用场景

  • 发送前检查邮件内容
  • 优化现有邮件模板
  • 学习邮件写作最佳实践

示例

from content_optimizer import ContentOptimizer

optimizer = ContentOptimizer()

content = """
【主题行】

正文内容...

行动号召...
"""

analysis = optimizer.analyze_content(content)
# 输出:字数、段落数、可读性评分、优化建议

3. A/B 测试主题行生成

生成多种风格的 A/B 测试主题行,包含性能预测。

主题行风格

  • 好奇型 - 制造信息缺口
  • 紧迫型 - 限时限量
  • 利益型 - 强调好处
  • 社会证明型 - 展示人数/权威
  • 提问型 - 引发思考
  • 列表型 - 数字清单
  • 故事型 - 叙述经历

性能预测基准

风格预测打开率预测点击率
好奇型22-28%3-5%

利益型20-26%5-8%
社会证明型23-29%4-6%
提问型21-27%3-5%
列表型24-30%4-7%
故事型22-28%5-9%

A/B 测试最佳实践

  • 样本量:至少 1000 订阅者/变体
  • 测试时长:24-48 小时
  • 成功指标:打开率
  • 次要指标:点击率

示例

from content_optimizer import SubjectLineGenerator

generator = SubjectLineGenerator()

# 生成 A/B 测试方案
ab_test = generator.create_ab_test(
    topic="邮件营销",
    goal="提升打开率",
    variants=3
)

# 输出:3 个不同风格的主题行变体 + 测试设置
