# Build Your Audience (Step 3)
> This guide will walk you through setting up your SMS campaigns in Avoca. Your CSM will walk you through this initially
### Prerequisites
Before getting started, ensure your Dashboard has the following pages enabled:
* **Texts**
* **Workflows**
* [Completion of Step 1 and 2 (create use case, setting up work flow)](/Setting-up-a-Workflow-Step-2-2f1f2b56d4d580939c46d3e6e5f31994)
If you don't see the Workflows page, please contact your Avoca representative to have it enabled.
## Step 3: Build Your Audience
Define who will receive your SMS campaign.
### Create an Audience List
Go to **Workflows** > **Audience Builder** > **+ New Audience List**
Choose your audience source:
* **Option 1: ServiceTitan Audience**
* Import audiences directly from your [ServiceTitan Marketing Pro account](https://help.servicetitan.com/how-to/create-audiences)
* Lists sync automatically with your ServiceTitan data
* **Option 2: XLSX Import**
* Upload a spreadsheet with your target contacts using [this template](https://docs.google.com/spreadsheets/d/14BSxk-jnfwEjvy9S69GD8V6cJPWyB0p1ebiJDDkRkIs/edit?gid=898861961#gid=898861961).
* *The upload WILL NOT work if they don’t save this as a regular .XLSX file and don’t follow this template.*
* Contact your Avoca representative for the correct template
* Include customer information like name, phone number, email, and address
* For ServiceTitan customers: Include Customer IDs to link with existing records
### Audience Settings
**Exclude Recently Contacted Individuals:**
* Prevents sending messages to people recently contacted via Avoca
* Set your desired exclusion window
**Excluded List:**
* Upload a list of phone numbers that should never receive messages
* Go to **Workflows** > **Exclusions** > **Upload List**
* *The only thing you need to do is upload a document with a single column with the column title: Phone Numbers 1*
### Testing Your Messages
Before launching a full campaign, we recommend testing:
Create a small test audience (max 20 contacts, or just your own number)
Click **Schedule** on your audience list
Select **Text** as the outbound channel
Select your use case
**Toggle on 'Test Run'** to enable testing
