# 再次匯入已存在後台的名單，會產生重複會員嗎？

Newsleopard 的名單管理機制，是以 Email address 當作唯一識別的欄位，一個名單可以隸屬於多個群組中，當群組被刪除時，名單只是從此群組移出，並不會跟著被刪除，當名單被刪除時，則包含該名單的所有群組皆會移除該名單。

任何的資料變更，皆會同步更新所有群組中相同會員的資料。

再次匯入既有名單，只會更新 Email 以外的欄位資料，並不會新增一筆名單。

# 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 dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://newsleopard.gitbook.io/help-center/features/lists/15.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
