How to Personalize Klaviyo Emails Using Lantern Quiz Responses

Personalized emails can make your quiz follow-ups more relevant to each customer. When Lantern sends quiz Property IDs to Klaviyo, you can use those profile properties to show different content based on a customer’s quiz responses.

There are two ways to personalize your Klaviyo emails:

We recommend using the first method when most of the email stays the same and the second method when customers should receive different emails, delays, or follow-up sequences.

Make sure that you have:

Use this method when all recipients can receive the same email, but selected text, images, or sections should change according to their quiz responses.

In our example we’ll use a pet food quiz. Customers who selected Dog in the quiz can see dog-related content, while customers who selected Cat can see cat-related content.

Drag a Text block into the email and enter your message. Place your cursor where you want the customer’s answer to appear, click the Personalization icon, then select the relevant Lantern Property ID.
​

In this example, enter Your dog’s name is, then select the dog_name property.
The result in the editor will look similar to:

Your dog’s name is dog_name

The dog_name property will appear as a personalization pill.

Select the Text block, then open the Display tab.
Under Show/hide logic, select Use logic builder.

Choose the dog_name Lantern Property ID, then select the condition that checks whether the property contains a value.

For example:

This means the Text block will only appear for customers who provided a value for the dog_name property. If the customer skipped the dog name question or the property has no value, the block will not appear.

Duplicate the first Text block, then update the duplicate for customers who provided a cat’s name.

Change dog to cat, then click the dog_name personalization tag and select Change property. Replace it with the cat_name Lantern Property ID.

Next, open the Display tab and update the Show/hide logic. Configure the Cat Text block to appear when both of the following conditions are met:

This ensures that Klaviyo displays the Dog Text block first when a dog name is available. If no dog name is available, it displays the Cat Text block when a cat name is available.

You will now have two personalized Text blocks:

Although both blocks are visible while editing the email, only the matching block will appear in the sent email.

Click Preview to confirm that the personalization property displays the correct value and that only the matching Text block appears.
You can also enter an email address and click Send test to review the email in your inbox.

Note: If both blocks appear or neither block appears, review the Show/hide conditions and confirm that the preview data contains the expected property values.

Add a separate Text block for each message, then use Show/hide logic to control which version appears.

For the Dog version, add:

Set it to appear when:

Duplicate the block, update the message for cats, then change the condition to:

Note: Replace pet_type, Dog, and Cat with the Property ID and answer values used in your Lantern quiz.

Add an Image block, then select or upload the image you want to display for customers who selected Dog.

Set the Image block to appear when:

Duplicate the Image block, replace the image with the Cat version, then update its Show/hide condition to:

You can upload an image, select one from your Klaviyo image library, or import an image using its URL.

You can apply the same Show/hide logic to other supported blocks and complete sections.

When an image, heading, text, and button should change together, duplicate the entire section and apply a different condition to each version.

This is easier than configuring each block inside the section separately. Klaviyo supports Show/hide logic at both the block and section level.

Use this method when customers should receive different emails or follow different sequences based on their Lantern quiz responses.

Navigate to the Flows tab in Klaviyo and create a new flow or edit an existing one.

When creating a new flow, go to Select your triggers → Your metrics → API, then select Completed Lantern Quiz (v2) followed by the slug of the quiz you want to use.

Keep Allow re-entry selected if you want customers to enter the flow again whenever they retake the quiz.

From the Logic section, drag the Split action into the flow where you want to create separate customer paths.

Select Add path criteria, then choose Properties about someone and select the relevant Lantern Property ID.
​

For the first path, set:

Select Add path, then create another path for:

Klaviyo automatically includes an Everyone else path for customers who do not match either condition.

Klaviyo checks the paths in order and sends each customer through the first path whose criteria they match.

Add an email or another flow action under each path, then customize it for that group.

You can use a saved email template or customize a new email for that path.
