# Audiences

> Create and manage contact lists for outbound campaigns

Audiences are your contact lists - the people your agents will call during campaigns. Each audience contains phone numbers and any additional information you want your agent to reference during conversations.

## Your Audiences

## Creating an Audience

Click **Create Audience** (green button, top right) to start a three-step process.

#### Upload CSV

![Upload CSV step](/_fern-img/51e5d5b55a3b9bc1e001ec35014a72e5d6f9b48ec859b3a072c5a6fc1df32a97.webp)

> **Warning**
>
> All recipients must have explicit consent to be contacted. Atoms prohibits purchased, rented, or third-party phone lists.

Upload a CSV with your contacts (max 10 MB). Your CSV needs a phone number column-everything else is flexible.

```csv
phoneNumber,Name,Email,CustomerID
919999900000,John,john@example.com,CUST001
919999900001,Alice,alice@example.com,CUST002
```

Phone numbers should be in international format (`+919999900000` or `919999900000`).

#### Map Phone Number

Tell us which column contains the phone numbers.

![Map phone number column](/_fern-img/bae4e219a7340cbc68feaaa7a7da7acfe4bc1c7d96b41f90daf94a986bf422f2.webp)

You'll see a preview of your CSV data. Select the column that contains valid phone numbers from the dropdown.

> **Tip**
>
> Only the phone number column needs to be mapped-everything else is up to you. Include any additional information you want available during calls (names, order IDs, account numbers, etc.).

#### Add Contacts

Give your audience a name and optional description.

![Name your audience](/_fern-img/32f40bb921404458fcaa86059ce175204e4dd34a7a7f98defe2026b38b2c3108.webp)

| Field         | Required | Example                                     |
| ------------- | -------- | ------------------------------------------- |
| Audience Name | Yes      | VIP Customers List                          |
| Description   | No       | High-value customers for premium promotions |

Click **Create Audience** to finish.

## Using Audience Data in Calls

The columns you upload become available as variables during campaigns. If your CSV has a "Name" column, your agent can greet callers by name.

See [Agent Config](/voice-agents/build/agent-settings) for more on Variables.
