# 10.5 邮件列表

如果你想宣传一款新产品，邮件列表很有用。有了计算机化的邮件列表，就可以做交叉匹配，更有效地锁定产品可能的目标消费者，从而把花在广告上的钱浪费到最少。

由于大多数用户组和杂志都会定期调查自己的读者，他们的邮件列表是绝佳的起点。其中包括 UniOps Books、/usr/group、Usenix、UNIXWORLD 和 UNIX REVIEW。其他的参见[印刷资料](/life/di-er-bu-fen-unix-xin-xi/4.-yin-shua-zi-liao.md)与[非印刷资料](/life/di-er-bu-fen-unix-xin-xi/5.-fei-yin-shua-zi-liao.md)两章。

另一个做广告的渠道是 Usenet，那里有一个专门发布新计算机产品公告的新闻组，叫 comp.newprod。注意，市场导向的吹嘘在这里不受欢迎。写这类帖子时，尽量站在科学、客观的角度。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://book.bsdcn.org/life/di-si-bu-fen-unix-zhi-wai/10.-unix-fu-wu/10.5.-you-jian-lie-biao.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
