# \[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.\
