The strategic integration of product blocks into your email campaigns is a powerful marketing lever to increase your conversions and personalize your customers' experience. Klaviyo offers advanced features allowing you to incorporate these visual elements dynamically or statically according to your business objectives. This detailed guide explains how to set up, optimize, and fully exploit the potential of product blocks in your Klaviyo emails.
What is a product block in Klaviyo and why use it?
A product block in Klaviyo is a modular marketing element that allows you to display specific items from your catalog directly in your email communications. These visual components can be configured to present either a manual selection of products or a personalized recommendation based on the individual behavior of each recipient.
Strategic advantages of product blocks for your email marketing
Integrating product blocks into your Klaviyo emails offers numerous measurable benefits:
- Significant increase in conversion rate: users can view and purchase products directly from their inbox
- Advanced personalization of the customer experience: each recipient receives recommendations tailored to their preferences
- Reduced number of clicks before purchase: shortening the customer journey to optimize conversions
- Effective promotion of discounted products: visual highlighting of special offers
- Enhanced catalog discoverability: exposing customers to more relevant products
- Improved campaign ROI: increased revenue generated by email
Types of product blocks available in Klaviyo
Klaviyo offers two main approaches to integrating products into your emails:
1. Dynamic product blocks
These blocks automatically adapt to each recipient, displaying personalized products based on:
- Recently viewed items by the customer
- Products added to the cart but not purchased
- Recommendations based on purchase history
- Complementary products to previous purchases
- Current trends and best sellers
This data-driven approach maximizes the relevance and effectiveness of your communications.
2. Static product blocks
These blocks present a fixed selection of products identical for all recipients, ideal for:
- Highlighting new arrivals in your catalog
- Promoting seasonal products or special offers
- Presenting a specific thematic collection
- Showcasing high-margin or overstocked products
This method offers total control over the items displayed in your campaigns.

Advanced strategies to maximize the impact of your product blocks

2. Strategic use in different campaigns
Adapt your product blocks according to the communication context:
Abandoned cart emails
Use dynamic blocks to:

- Present complementary items to those abandoned
- Suggest alternatives in similar price ranges
Welcome emails
Integrate static blocks to:
- Present your flagship products or best sellers
- Introduce different categories from your catalog
- Highlight special offers for new customers
Post-purchase emails
Use dynamic blocks to:
- Suggest accessories compatible with purchased products

3. Design optimization for conversions
Improve the visual effectiveness of your product blocks:

- Integrate "New," "Popular," or "Limited Stock" badges to create a sense of urgency
- Add strikethrough prices next to promotional prices to emphasize the value of the offer
- Use contrasting and inciting call-to-action buttons ("Shop Now," "View Offer")
4. A/B testing to identify optimal configurations
Experiment with different approaches to maximize performance:
- Test the effectiveness of 3 vs 6 displayed products
- Compare the performance of dynamic vs static blocks
- Evaluate different block positions in the email
- Measure the impact of product reviews on conversion rates
Key metrics to evaluate the effectiveness of your product blocks
To measure and optimize performance:
- Click-through rate per product: identify which product types generate the most engagement
- Conversion rate from email: measure how many clicks turn into sales
- Average order value: determine if product blocks increase average cart value
- Email ROI: calculate revenue generated relative to campaign costs
- Unsubscribe rate: verify that adding products does not increase unsubscribes
Concrete examples of high-performing product blocks
Example 1: Personalized recommendation email
A fashion brand uses dynamic blocks showing recently viewed items by each customer, complemented by recommendations for similar items. Result: a 34% increase in conversion rate compared to standard emails.
Example 2: Collection launch email
A furniture website presents its new collection with a static block highlighting 6 key pieces, each with an average rating of 4.5+ stars. Result: a 28% increase in traffic to new products.
Example 3: Re-engagement email
