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. If prompted, choose Static under Quote selection.
   

1. Click Add review quote.
2. Click Select next to the review you want to feature. If a highlight is available, choose Select full review or Select review highlight.
   • You can toggle between product reviews and store reviews, or filter by various criteria (e.g., rating, product, verification status, and more).

3. If desired, adjust the colors, fonts, and sizes used in the block in the Styles tab.
4. In the Content tab, you can use Change quote to replace the selected review. Use Review details and Review formats to adjust what appears in the block and its layout.
5. Click the back arrow to return to the email.

Add a dynamic review

Follow these steps to dynamically highlight reviews for a product in each recipient’s flow trigger. The block displays featured reviews you choose for that product. You can also set fallback options for products without featured reviews.

Dynamic reviews are supported for event-triggered flows, back in stock flows, low inventory flows, and price drop flows.

1. Navigate to a supported flow email in Klaviyo.
2. Drag a Review quote block into the email.
   

3. Choose Dynamic under Quote selection. If you do not see this option, then the message you are editing doesn’t support dynamic quote blocks. Head to an event-triggered flow.
4. Depending on your flow’s trigger, the product may be automatically selected.
   • If the product is auto-selected, you’ll see your flow’s trigger event under Product selection. Klaviyo uses the first product in the trigger’s list.

• If the product is not auto-selected, enter a product ID variable in Product ID variable. Learn how to select the right variable.

5. Under Review selection, click Manage featured reviews, then click View reviews next to a product.
6. Click Feature next to a review. If a menu appears, choose Add to featured reviews for the full review or Feature review highlight for its highlight. Click Close when finished.
7. Under Review selection, click Manage fallback options to choose what appears when the product has no featured reviews:
   • High-quality review for the product: use a review with a 5-star rating, positive sentiment, and no profanity. Optionally, select Set an additional static fallback review, then Add fallback review to choose a review for products without a high-quality review.
   • Static review: click Add fallback review and select a review to use for all products and recipients when there is no featured review.
   • No review: hide the block when the product has no featured reviews.
8. Click Done to confirm your fallback options.
9. If desired, adjust the format in the Review formats section, or change the colors, fonts, and sizes in the Styles tab.
10. Click the back arrow to return to the email.
11. Click Preview and preview with the flow’s event data to check that the product and review appear as expected. Check any manually entered product ID variable before sending; an incorrect variable can prevent the email from being delivered.

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 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:

• Your filters exclude the review you want.
  Adjust the rating or other filters in the review picker, then try again.
• 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.
