## Setting Up a Text Campaign

Text campaign setup defines how your AI agent sends and receives messages and when messages are delivered. Proper configuration ensures your campaign runs smoothly.

## Creating a New Text Campaign

1. Navigate to your Callers dashboard.
2. Click the **New Campaign** button.
3. Select **Text** as the campaign type.
4. Enter a **Campaign Name**.

## General Settings

### Campaign Details

* **Campaign Name**: A descriptive name for internal reference.
* **Campaign Type**: Choose between **Outbound** (you initiate) or **Inbound** (contacts initiate).
* **AI Instructions**: Provide general guidelines for the AI agent's behavior and tone across all conversations.

<Info>
  For channel setup details, see the integration guides for [Twilio SMS](/documentation/text-campaigns/twilio-sms), [Telnyx SMS](/documentation/text-campaigns/telnyx-sms), or [WhatsApp](/documentation/text-campaigns/whatsapp).
</Info>

## Availability

Configure when your text campaign is active and how follow-ups are handled. Open the **Availability** modal from your campaign settings.

### Time Zone

Select the time zone for message scheduling (e.g., `(GMT-05:00) America/New_York`).

### Sending Days and Hours

* **Sending Days**: Click the day buttons to toggle which days of the week messages can be sent (e.g., Monday through Friday).
* **Sending Hours**: Define the daily time window for sending messages (e.g., 9:00 AM - 5:00 PM).

### Attempts

* **Total Follow Up Attempts**: Set the number of follow-up messages the AI agent will send if a contact does not respond.
* **Min Wait Time Between Follow Up Attempts**: Set the minimum wait time between follow-ups, in minutes or hours.

### Custom Follow-Up Prompt

Follow-ups are auto-rephrased by the AI. Add custom instructions to adjust the content and tone of follow-up messages.

<Info>
  Follow-up messages will only be sent during your configured availability hours. If a follow-up is scheduled outside of those hours, it will be held and sent at the start of the next available window.
