When a shopper completes your quiz, they’re telling you exactly what they want.

The problem is that most brands only use that data on-site.

By sending quiz results into Klaviyo, you can turn those insights into personalized email experiences that feel more relevant to subscribers and more effective for driving conversions long after the quiz is complete.

For one brand, sending Klaviyo product recommendation emails led to over $70k in email revenue in just under 8 months and it all started with a custom Klaviyo quiz powered by Digioh. In fact, 91% of consumers are more likely to shop with brands that recognize, remember, and provide them with relevant offers and recommendations. Personalized product recommendations can also significantly increase average order value, with one client reporting a 35% jump after implementing them in email flows. With quizzes, you can capture customer data that leads to:

  1. Instant conversions
  2. Customer profile building
  3. Email flow revenue

Your ideal customers may need the products that you sell, but you must let them know about them. A simple, fast quiz can help you educate your customers, drive sales, enrich your customer profiles, and create an email flow that recommends the perfect products to them.

Klaviyo product recommendations perform better when they’re personalized. The more relevant the experience, the more revenue you generate from your list.

What are Product Recommendation Emails?

Let’s say a visitor completes your quiz but leaves before making a purchase. By emailing customers their results, you provide shoppers with a handy way to retrieve their recommended products, and you earn your brand another chance at conversion. Klaviyo allows you to display recommended products using dynamic recommendation blocks within the email template, making it easy to personalize each message throughout the customer journey.

Health-Ade sends their quiz takers a product recommendation email containing their quiz results and a unique discount code.

In these blocks, Klaviyo assigns product images automatically, ensuring each recommended item is visually represented—even using default images if a specific image is missing. You can select any existing product feed or create a new one from within the template editor, enabling dynamic updates based on inventory and customer trends.

After all, if someone spends the time to take your quiz, they’re probably pretty interested in your products. Whether a shopper isn’t ready to buy or forgets to complete their purchase, putting the perfect products in their inbox can be a great way to drive purchases and get the most from your quiz investment. AI-powered product blocks can display items based on a user's behavior, ensuring more targeted recommendations.

To maximize results, it’s important to test different recommendation blocks, product feeds, and layouts—A/B testing can help optimize engagement and revenue.

Increase Revenue with Klaviyo Product Recommendation Emails

Whether you use Klaviyo or another email service provider, product feed recommendation emails are one of the most effective ways to drive more sales from your list.

In fact, we’ve consistently seen these emails convert at rates equal to or higher than abandoned cart campaigns because the recommendations are tied directly to shopper preferences and purchase intent.

Here’s how it works:

  • Create a product recommendation quiz tailored to your shoppers and product feed catalog.
  • Connect your quiz to your ecommerce platform and Klaviyo account. Digioh makes this easy by syncing quiz responses, customer attributes, and product data in real time so recommendations stay accurate and relevant. Product feeds are available by default for many ecommerce integrations, and custom catalogs can be synced through the API when needed.
  • Build a dynamic email flow inside Klaviyo using quiz response data. You can personalize recommendations based on shopper preferences, while also using filters like price range and inventory availability to ensure the products being shown are actually purchasable.
  • Launch and promote your quiz across your site, email campaigns, paid traffic, and pop-ups to drive participation.
  • Once a shopper completes the quiz, Klaviyo automatically sends a personalized email featuring their quiz results and recommended products, extending the value of the quiz beyond the on-site session.

You can use the data collected through your quiz to segment your email list and show the most relevant products, promotions, and content.

Collaborative filtering and RFM (Recency, Frequency, Monetary) segmentation can further personalize recommendations for each given customer, while behavioral triggers like Browse Abandonment and Abandoned Cart can display products a user has interacted with. Using rules-based product recommendations, marketers can showcase products customers have recently viewed, added to their cart, or best-selling items, enhancing personalization.

For example, swimwear brand Andie’s Fit Quiz recommends products to users based on their:

  • Activities (lounging, lap swimming, etc.)
  • Size
  • Torso length
  • Height
  • Coverage and support preferences

After completing the quiz, shoppers receive personalized product recommendations based on their style preferences and individual sizing, creating a more relevant follow-up experience than a standard promotional email.

The impact was significant: more than $70K in revenue generated from a single Klaviyo product recommendation email and a 55% year-over-year increase in email flow revenue. And that’s in addition to the revenue generated from shoppers who converted immediately after completing the quiz.

Tips for Sending Product Recommendation Emails with Klaviyo

To ensure your email makes the biggest impact possible, we recommend doing the following:

  • Create a quiz that accommodates shopper needs, sizes, and preferences to make the best recommendations.
  • Send product feed recommendation emails 10 – 20 minutes after the quiz is completed, if they do not make a purchase.
  • Use a 'Recently Viewed' product feed to show items a customer looked at but didn't buy, especially in browse abandonment emails.
  • Incorporate social proof, such as product reviews and product ratings, in your recommendation emails to encourage purchases and increase trust.

This strategy works just like cart abandonment emails. When a visitor scours your site for 1-3 minutes before adding something to their cart, you know they’re invested. Similarly, quiz takers have already spent a few minutes filling out your quiz, but they may not have the time to complete a purchase.

However, if a shopper fills out a quiz, they have high intent, and you can reach them with your re-marketing strategy. Focus on key metrics like open rates, click-through rates, and conversions to optimize your recommendation strategy.

Users can also revisit the recommendation email on any other device that they use.

Customer Success Story: Andie

Andie started with the goal of:

  • Increasing customer acquisition
  • Leveraging zero-party data
  • Boosting repeat purchases

Andie rebooted their Fit Finder quiz with Digioh to meet the goals outlined above, launching a new quiz that sends a product recommendation email to all quiz takers.

Andie leveraged Klaviyo's product recommendation tools to personalize these emails, enhancing the relevance of each message and driving better engagement.

The results of this automated email speak for themselves:

  • 55% YoY growth in revenue from email flows
  • A 70.9% lift in click-through rates for quiz results emails
  • $70k+ in additional revenue from flows

We can help you create your own Klaviyo product recommendation quiz results email to experience the power of a Klaviyo quiz and how it can drive more sales and increase customer satisfaction.

More Opportunities to Grow Email Revenue with Quizzes

The benefits of product recommendation emails don’t end with the initial results email. Quizzes provide valuable zero-party data that you can leverage to further grow your email revenue. Including your most popular products in welcome emails is a great way to introduce new subscribers to your brand’s bestsellers and encourage early engagement.

When using quiz data, you can personalize the shopping experience by displaying customers' products they have recently viewed, added to their cart, or shown interest in. Leveraging a product feed allows you to automate and offer personalized experiences, ensuring each customer sees relevant products based on their activity and preferences.

For post-purchase flows, allow time for the customer to use their initial purchase before sending cross-sell recommendations—this optimizes timing and increases the likelihood of conversion. Remember, personalized recommendations consistently yield better engagement than static best-seller lists.

Send Reminder Emails

Let’s say a shopper completes your quiz, receives their personalized product recommendation email, but doesn’t purchase right away.

That doesn’t mean the opportunity is gone.

A follow-up email sent a few days later can re-engage that shopper with their quiz results, recommended products, and a personalized incentive like a unique discount code or free shipping offer.

Often, shoppers just need a reminder. Re-surfacing products that already align with their preferences and purchase intent can be enough to bring them back and drive the conversion.

Build Customer Profiles

The zero-party data you collect from your quiz can be used to build customer profiles in Klaviyo. When your questions are carefully planned, you provide customers with their results and gather valuable information to build customer profiles, such as:

  • Name
  • Age
  • Gender
  • Location
  • Budget
  • Favorite brand
  • Goals or pain points
  • Preferred contact method

Sometimes, a quiz can provide surprising results and insights. For example, men's jewelry Jaxxon assumed that their customers were primarily women purchasing gifts for men. However, their quiz data painted a different picture.

When asked, “Are you shopping for yourself or someone else?” to Jaxxon's surprise, most quiz takers reported shopping for themselves.

That one question gave Jaxxon tremendous insight into who their customer is, and that data can ensure their marketing messages are targeted at the right people.

Segment Your Klaviyo Lists

You can also use zero-party data from your Klaviyo-connected quizzes to segment your list and create targeted flows in Klaviyo.

Segmenting your list and creating targeted flows in Klaviyo ensures that subscribers see messages based on their needs or preferences.

It's another level of personalization that can help improve open rates and conversions while reducing unsubscribe rates.

Email Quizzes to Customers Who Haven’t Taken Them

Because product recommendation emails and personalised experiences boost conversion rates, it makes sense to get as many customers as possible to take the quiz.

To grow your email revenue, make sure you promote your quiz to subscribers who haven't taken it yet.

Product recommendation emails are an effective way to grow your email revenue and overall sales. They help customers find what they need, making them more likely to make a purchase.
