# \[Troubleshooting] How to target a large number of users at the same time?

When doing experimentation or feature management on Flagship, you need to **target the right users at the right time**. For example, you may want to deploy a new feature **to your early adopters only**. However, you may have a **list of over a hundred** early adopters.

In the targeting step, you can target a list of values when creating or editing a use case. There are 3 ways of doing this:

* Manually adding the values of the users you want to target (*Users by ID* or *Key*) in the *Values* field. These values (ID, email, and so on) allow Flagship’s Decision API to identify the users you want to target among all your users.
* Copying and pasting the values of the users you want to target (*Users by ID* or *Key*) in the *Values* field and **pressing *****ENTER***. Each value must be separated by a comma.\

* Importing the values related to the users you want to target in a **CSV file** by clicking on the Import CSV icon at the edge of the field. You must fill in the **first column only**, so that all the values are taken into account.\

# 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://docs.abtasty.com/flagship-deprecated/steps-configuration/troubleshooting-how-to-target-a-large-number-of-users-at-the-same-time.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.
