# Audience
> Define who receives your SMS campaign.
The first step in creating an SMS campaign is selecting your audience — the group of contacts who will receive the text message.
This is a dashboard walkthrough. Screens are captured from **cloud.comify.io** → **Template Manager → Campaign Manager**.
Want to build your audience ahead of time, or keep it updating automatically? See [Segments](/audience/segments) (dynamic) or [Lists](/audience/lists) (static, from a rule or CSV) — built from the Audience List page — then select it here.
## Getting started
From **Template Manager → Campaign Manager**, click **Create campaign**, give it a **Name** and optional **Description**, and select **SMS** under **Channel**. Click **Create campaign** to open the wizard — the stepper shows **Audience → Content → Scheduling**, and you land on the Audience step.
## Attaching an audience
Upload a new CSV file with your contacts. Rows are validated before the campaign launches. Each column in your CSV becomes an available field for variable mapping in the next step.
Pick from a previously uploaded audience list or a dynamic segment. New uploads appear as "pending" until processing completes.
### Selecting an existing list
Click **Select existing** to open the audience picker, with two tabs:
| Tab | What it shows |
| ---------------------- | --------------------------------------------------------------------------------------------------------------------- |
| **Campaign audiences** | Lists you've uploaded or built from a rule, with Contacts, With Email, Status, and Updated. |
| **Comify segment** | Dynamic segments (built with **+ New**) that re-qualify members at send time — the member count shown is an estimate. |
Click **Select** next to the list you want.
## After attaching an audience
Once an audience is attached, Comify shows a summary of the list, its **Available fields**, and a sample of the first rows so you can verify the data before proceeding.
| Field | Description |
| ------------------ | ------------------------------------------------------------------------------ |
| **Total Audience** | Total number of contacts in the list |
| **Sendable** | Contacts with a valid phone number who will receive the SMS |
| **Excluded** | Contacts skipped due to missing/invalid phone number, opt-outs, or suppression |
Contacts without a valid phone number are automatically excluded from SMS sends.
## Next step
Once your audience is attached and the sendable count looks right, click **Continue** to move to [Content](/campaigns/sms/content).
