**Note**

The terms *audiences* and *segments* are interchangeable. Optimizely has updated all *segments* to *audiences* on the **Audiences** page and is updating the UI on other pages. See  [Understand audiences](docId\:v-gHiL9jfINBey-4QNtFM) to get information on audiences.
:::

Optimizely Data Platform (ODP) lets you create automated SMS campaigns triggered by keywords in text messages your customers send you. You can use keyword-triggered SMS campaigns to automate your responses (like support requests) or help your customers opt in to lists (like hobbies, interests, or concerns).

Email and SMS channels are legacy features and not offered to new customers.

## Create a filter for incoming SMS keywords

Create a new filter for incoming text messages containing *support*.

1. Go to **Data Setup > Filters > Create New Filter**. 
2. Name your filter *SMS Engagement – Support*. 
3. Select **Visibility > Account** and **Feed > Events**.
4. Enter the following filter definitions:
   - **Event Type = sms**
   - **Event Action = engage**
   - **Campaign Event Value ≈** **support**. Use *matches* as the operator instead of *equal* to avoid capitalization issues.

5. **Save** your filter.

## Preview and activate your SMS campaign

1. Click **Preview** to see what your SMS displays to your target audience. Click on the preview image to see the full message in the phone’s messaging app.
   - The character counter under the preview displays the number of characters your message contains and shows the estimated number of messages sent per user.
   - The character counter is blue when you are within the 160 or 70-character limit and orange when you are over the character limit.

2. Click **Go Live** after completing your text message. When a customer sends a text with *support*, your automated campaign sends your customers a reply with a link to your support page.
