How to feature reviews in emails with the review quote block

You will learn 

Learn how to feature a product review within a campaign or flow email via the Review quote block. With Klaviyo Reviews, you can use this block to feature customer testimonials and ratings to build trust in your brand and create social proof. 

Before you begin

This block is only available in accounts that use Klaviyo Reviews. Learn how to get started with Klaviyo Reviews. 

There are 2 types of review blocks you can add: 

• Static reviews
  Show the same featured review to everyone who receives your email. 
• Dynamic reviews
  Highlight a review based on a product someone has recently interacted with (e.g., a positive review for an item in their abandoned cart reminder). This option is available only in event-triggered flow emails with product information.

Add a static review

Follow these steps to feature a single review in an email. The same review is shown to all recipients. 

1. Navigate to any email in Klaviyo (i.e., a flow email, draft campaign email, or email template). 
2. Drag a Review quote block into the email.
   
3. Click Add review quote. 
4. Choose Static. 
5. Click Add review quote and choose a quote to feature. 
   
   1. You can toggle between product reviews and store reviews, filter by various criteria (e.g., rating, product, verification status, and more), or choose between full reviews and AI-selected highlights using the filter menu. 
      
6. If desired, adjust the colors, fonts, and sizes used in the block in the Styles tab. 
7. In the Content tab, change the selected quote and block styles.
8. Click Done. 

Add a dynamic review

Follow these steps to dynamically highlight different reviews and different products for different recipients. You can choose to highlight featured reviews, or rotate through a selection of the best positive reviews for a selected product. You can also choose whether to highlight reviews from the same product for all recipients, or to dynamically display reviews for an item the recipient viewed or added to cart recently. 

1. Navigate to any email in Klaviyo (i.e., a flow email, draft campaign email, or email template). 
2. Drag a Review quote block into the email.
   
3. Click Add review quote. 
4. Choose Dynamic. 
5. Under Prioritize recent quotes from, choose Featured reviews or High-rated reviews.
    
6. Under Product selection, select Add product, or if this message is part of an event-triggered flow, choose choose Manual or Automatic. 
   • If you choose Automatic, add an event variable that references a product’s ID. This is only supported in certain flows. Learn how to choose the right event variable. 
7. If desired, adjust the format in the Review formats section, or change the colors, fonts, and sizes in the Styles tab. 
8. Click Done. 

How reviews are selected

The Review quote block can only display reviews submitted by a verified purchaser. Unverified reviews cannot be selected or displayed in this block type. Additionally, only 4- and 5-star reviews appear in the selection modal by default, but you can adjust this filter. 

If you aren’t yet able to select a review or if your dynamic review block appears blank, it may be because: 

• There aren’t enough high-quality reviews in your account to select from.
  Check back at a later date for a selection of reviews. 
• Your reviews haven’t yet been processed.
  If you’d like to feature a brand-new review, wait a few hours before trying again.
• The reviews in your account aren’t verified.
  To be verified, a review must be submitted through a personalized link in a Klaviyo review request flow or marked as verified in an uploaded CSV of reviews from another platform. Unverified reviews, including reviews submitted directly to your site, are not eligible for inclusion in a review quote block. Wait until you’ve collected verified reviews, or upload verified reviews.
• There are no reviews for the selected product that meet the criteria to be displayed.
  Change your settings or collect more reviews.
