Using Loox Parameters in Klaviyo Review Request Emails

Create customized Klaviyo email templates that use Loox parameters. You can build flows on Klaviyo for review requests or review request reminders, or create follow-up flows based on the reviews your customers submit to Loox.


To implement Loox parameters in your Klaviyo email templates, first make sure to activate your Klaviyo integration and select or create the email template you wish to use.

  • Once the body of the email is written, add a new section block:
  • In the section's Display menu, click "Add content repeat:"
  • Create content repeat rules using the following parameters:
    Repeat for:
    event.items
    Item alias:
    item
  • Next, add an image block and click "select image":
  • In the image selection window that opens, select dynamic image and enter the following Loox parameter:
    {{ item.image_url }}

Tip: We recommend adding a fixed width of 200px for the product image.

  • To display the customer's purchased items in the email, add a text block and click "edit text:"
  • Next, add the following Loox parameter:
    {{ item.name }}
  • To add a "Write a review" button that redirects your customers to the product's review form, add a "Button" block that uses the following Loox parameter:
    {{ item.review_url }}

Tip: We recommend changing the button's text to "Write a review".

That's it! Using these parameters, your Klaviyo email template will display your customer's order information and collect their reviews using a dedicated "Write a review" button.


Below are some additional Loox parameters that can be used to add customer data into your emails:
