## How to Create a Metric-Triggered Flow in Klaviyo

Once PreOrder Guru is connected to Klaviyo and your metrics are available, you can use them to create automated flows.

For example, you can create a flow for a **Preorder Confirmation** using the **PG Preorder Activity** metric.

The same process can be used with the other PreOrder Guru metrics to create different automated flows.

### Example: Create a Preorder Confirmation Flow

### Step 1: Create a New Flow

1. Log in to your **Klaviyo** account.
2. Go to **Flows**.
3. Click **Create Flow**.
4. Select **Create from Scratch** or **Build Your Own**.
5. Enter a flow name, such as **Preorder Confirmation**.

### Step 2: Select the PreOrder Guru Metric

Select **Metric** as the flow trigger.

Choose API and select: **PG Preorder Activity**

![](https://preorder-guru.webframez.com/wp-content/uploads/2026/09/image-4-1024x463.png)

The **PG Preorder Activity** metric includes:

- Preorder Confirmation
- Partial Payment Due Soon
- Partial Payment Overdue
- Partial Payment Reminder

Since this example is for a **Preorder Confirmation**, we need to add a trigger filter so the flow only runs when a preorder confirmation event is sent.

### Step 3: Add a Trigger Filter

![](https://preorder-guru.webframez.com/wp-content/uploads/2026/09/image-5.png)

After selecting **PG Preorder Activity**:

1. Open the **Trigger Filters** section.
2. Add a filter using the **Action Type** event property.
3. Set the filter to the value used for **Preorder Confirmation**.
4. Save the trigger settings.

The `actionType` variable identifies which activity triggered the **PG Preorder Activity** metric.

![](https://preorder-guru.webframez.com/wp-content/uploads/2026/09/image-12.png)

**Note:** The `Action Type` property allows you to differentiate between the four events included in **PG Preorder Activity**. When creating a Klaviyo metric-triggered flow, use the appropriate `actionType` value as a **trigger filter** to make sure the flow sends the correct email template for that event.

## Step 4: Create a Dynamic Preorder Confirmation Email

### Step 1: Add an Email to the Flow

1. Add an **Email** action below the trigger.
2. Click **Edit Email**.
3. Choose a template or create a new email template.
4. Add your preorder confirmation message.
5. Use PreOrder Guru event variables to display dynamic customer and preorder information.
6. Save the email.

### Step 2: Add a Product Information Block

To display the preorder products:

1. Add a **Table**, or other suitable content block to your email.
2. Add the product information you want to display, such as:
   - Product name
   - Product image
   - Quantity
   - Price
   - Variant
   - SKU
   - Expected shipping date

Since a customer can have one or multiple preorder products, use Klaviyo's **Content Repeat** option to make the product section dynamic. This allows Klaviyo to automatically repeat the product information for each preorder item in the customer's order.

### Step 3: Set Up Content Repeat

Now configure the block to repeat for each preorder product.

1. Select the content block you created.
2. Open the **Display** tab in the block settings.
3. Scroll down to **Content Repeat**.
4. Click **Add Content Repeat**.
5. In **Repeat for**, enter: event.preorderData.preorder
6. In **Item alias**, enter: item
7. Click **Save**.

![](https://preorder-guru.webframez.com/wp-content/uploads/2026/09/image-7.png)

### Step 4: Add Dynamic Variables to the Block

Once Content Repeat is configured, use the `item` alias to display information for each preorder product.

![](https://preorder-guru.webframez.com/wp-content/uploads/2026/09/image-9-1024x472.png)

![](https://preorder-guru.webframez.com/wp-content/uploads/2026/09/image-10.png)

### Step 5: Add Customer Information

Customer information can be added outside the Content Repeat block because it only needs to appear once in the email.

### Step 6: Preview the Email

After adding the variables:

1. Save your email template.
2. Use **Preview & Test** in Klaviyo.
3. Select a profile/event containing PreOrder Guru preorder data.
4. Check that the product information is displayed correctly.
5. Make sure the product block repeats when the customer has multiple preorder items.

![](https://preorder-guru.webframez.com/wp-content/uploads/2026/09/image-11.png)

### Step 07: Set the Email to Live

Once you have finished testing:

1. Return to the email settings in the flow.
2. Make sure the email is configured correctly.
3. Change the email status to **Live**.
4. Review the flow once more.
5. Turn the flow **Live**.

The flow will now automatically send the preorder confirmation email when PreOrder Guru sends a matching **Preorder Confirmation** event to Klaviyo.

---

## Use the Same Process for Other PreOrder Guru Events

Once you understand this setup, you can create additional Klaviyo flows using the other PreOrder Guru metrics.

For **PG Preorder Activity**, you can create separate flows by changing the **Action Type** filter:

- Preorder Confirmation
- Partial Payment Due Soon
- Partial Payment Overdue
- Partial Payment Reminder

For the other metrics, select the relevant metric as the flow trigger and use the variables provided in the **Klaviyo Metrics & Variables** section of this article.

---

## Ready-to-Use Klaviyo Email Templates

To make the setup easier, PreOrder Guru provides **ready-to-use Klaviyo email templates** with the required variables already configured.

You can copy these templates into your Klaviyo account and customize the branding, content, and styling according to your store. These templates can help you quickly set up automated emails for different preorder events without manually adding each variable.

### **Import into the other account**

1. Log into the other Klaviyo account.
2. Go to **Content > Templates**.
3. Select the **Email templates** tab.
4. Click **Import**.
5. Enter a name for the template and upload your `.html` file.
6. Click **Import Template**.

**One thing to note:** Klaviyo advises that exporting a drag-and-drop template and re-importing it back into Klaviyo can sometimes cause issues with functionality. If you run into any problems, you may need to tweak the HTML before importing. [How to import a custom HTML template](https://help.klaviyo.com/hc/en-us/articles/115005254068).
