Pinterest generates over $80 billion in e-commerce sales in the United States, and 85% of active users make a purchase after seeing a Pin. Yet, many e-commerce businesses don't leverage the full potential of their customer data on this platform.
Pinterest advertising shows impressive results, with a ROAS 2 times higher than other social platforms for retail brands. But to maximize these performances, you need to personalize your campaigns with your own customer data rather than relying on basic demographic targeting.
The Pinterest-Klaviyo integration solves this challenge by directly connecting your Klaviyo segments to your Pinterest ad audiences. No more manual exports and development hours: you sync your first-party data in a few clicks to create ultra-targeted campaigns.
In this guide, you'll discover how to set up this integration, leverage your Klaviyo segments to optimize your Pinterest campaigns, and maximize your advertising return on investment through advanced targeting strategies.
Why integrate Pinterest with Klaviyo?
The competitive advantage of first-party data
Using first-party data in advertising generates an average of 2.9 times more revenue and 1.5 times more savings, according to a Think With Google study. But the challenge lies in effectively transferring this data to your advertising platforms.
Traditionally, personalizing your Pinterest campaigns with your Klaviyo data required custom development or time-consuming manual exports. This fragmented approach leads many marketers to settle for basic demographic targeting, neglecting the richness of their behavioral data.
The native Pinterest-Klaviyo integration eliminates this friction. Your segments based on purchase history, email engagement, or on-site behavior automatically sync with Pinterest. This allows you to intelligently retarget abandoned carts or create lookalike audiences based on your best customers.
Immediate business benefits
This integration transforms your Pinterest advertising approach in several concrete ways. Rather than targeting broadly and hoping to reach the right people, you deliver personalized messages based on each prospect's stage in your conversion funnel.
Your retargeting campaigns become surgical. A customer who abandoned their cart sees an ad for their exact products, while a VIP buyer discovers your latest premium arrivals. This personalization naturally improves your conversion rates and ROAS.
The integration also optimizes your advertising budget by automatically excluding irrelevant segments. Why spend money targeting a customer who just bought and likely won't buy again for several months? Smart exclusion focuses your budget on the prospects most likely to convert.
Enhanced cross-channel consistency
One of the often-overlooked benefits concerns the consistency of your cross-channel communication. Your Klaviyo emails and Pinterest ads can now convey complementary messages based on the same behavioral segments.
A customer who receives a winback email in Klaviyo can also see a Pinterest ad with a similar offer, reinforcing the impact of your message. This omnichannel approach improves recall and accelerates conversion.
Prerequisites and preparation
What you need before you start
On the Klaviyo side, make sure you have an active account with enough customer data to create meaningful segments. The integration works best when your segments contain at least a few hundred profiles. Also, verify that your e-commerce integration (Shopify, WooCommerce, etc.) is working correctly to feed Klaviyo with rich behavioral data.
Prepare your priority segments before integration. Identify the 3-5 segments you want to test first: recent abandoned carts, VIP customers, non-converting visitors, or buyers of a specific category. This preparation speeds up setup and allows you to quickly test the impact.
On the Pinterest side, you need a Pinterest Business account with administrator rights to the ad account you want to connect. If you manage multiple ad accounts, note that you can only connect one per Klaviyo account.
Important limitations to be aware of
The integration has some important technical constraints. Each Klaviyo account can only connect to one Pinterest ad account. If you manage multiple brands or accounts, you will need to choose the most strategic one or create separate Klaviyo accounts.
Synchronization works in a strict 1:1 mode. A Klaviyo list or segment can only connect to one Pinterest audience, and vice versa. This limitation requires rigorous organization of your audiences to avoid conflicts.
Synchronized Pinterest audiences will generally be smaller than your original Klaviyo segments. Pinterest can only match profiles that have a Pinterest account associated with the email in your Klaviyo database. Depending on your industry, this match rate varies from 30% to 70% of your initial segment.
Step-by-step integration guide
Setup in 10 minutes flat
Step 1: Access Klaviyo Integrations
Log in to your Klaviyo account and click on the “Integrations” tab in the main menu. This section centralizes all your connections with external platforms.
Step 2: Install the Pinterest Integration
Click on “Add integrations” and search for “Pinterest Audiences” in the list. Select the Pinterest card and click “Install” to start the installation process.
Step 3: Connect your accounts
Click on “Connect to Pinterest Audiences”. You will be redirected to Pinterest to log in if necessary. Carefully review the requested permissions and click “Give access” to authorize the connection.
Step 4: Select the ad account
If you manage multiple Pinterest ad accounts, select the one you want to integrate. If you only manage one, it will appear pre-selected automatically.
Step 5: Configure connections
The interface shows you two columns: your Klaviyo lists/segments on the left, and your Pinterest audiences on the right. Select a Klaviyo segment from the left dropdown menu, then choose a corresponding Pinterest audience on the right.
Step 6: Create new Pinterest audiences
To create a Pinterest audience directly from Klaviyo, click the “Select an audience” dropdown, type the name of your new audience, then click “+ Create audience”. This feature avoids back-and-forth between platforms.
Step 7: Add multiple connections
To connect other segments, click “Add connection” and repeat the process. Organize your connections logically: abandoned carts → Pinterest abandoned cart audience, VIP → Pinterest VIP audience, etc.
Step 8: Finalize the setup
Once all your connections are configured, click “Complete setup”. A success message confirms that your Pinterest account is now connected to Klaviyo.
Step 9: Wait for synchronization
The initial synchronization can take up to 48 hours. Klaviyo immediately starts sending your profiles to Pinterest, but matching and populating audiences takes time.
Points of vigilance during installation
Verify that your Pinterest account has "Audience" or "Ad account admin" permissions. Without these rights, the integration will fail during connection.
Adopt a consistent naming convention for your Pinterest audiences. For example, prefix them with "KL_" to easily identify those synced from Klaviyo and distinguish them from your native Pinterest audiences.
If you manage existing Pinterest campaigns, document your current audiences before integration. This avoids confusion when creating new campaigns.
How synchronization works
Understanding sync mechanisms
Synchronization between Klaviyo and Pinterest is not instantaneous and follows precise rules that must be understood to optimize your campaigns.
Synchronization timing
The first synchronization after connecting a segment takes up to 48 hours. Pinterest needs to match the emails in your Klaviyo segment with its user base, which requires processing. Subsequent updates (adding or removing profiles in your segments) follow the same delay.
This latency requires early planning for your campaigns. If you're launching a Black Friday campaign, set up your segments and audiences at least 48 hours in advance to ensure their availability.
Matching behavior
Pinterest matches your Klaviyo profiles by comparing email addresses. Only profiles with a Pinterest account associated with those emails will appear in your synchronized audiences. This process explains why your Pinterest audiences are generally smaller than your original Klaviyo segments.
The match rate varies depending on your industry and audience. Lifestyle, home decor, or fashion brands generally achieve better rates (50-70%) because their customers use Pinterest more. B2B or highly technical sectors may see lower rates (20-40%).
Dynamic audience evolution
Your Pinterest audiences automatically evolve based on changes in your Klaviyo segments. If a customer exits your "abandoned cart" segment after a purchase, they also disappear from the corresponding Pinterest audience within 48 hours.
This bidirectional synchronization maintains the relevance of your campaigns without manual intervention. Your advertising budgets automatically focus on the profiles most likely to convert according to your Klaviyo criteria.
However, be aware: if you connect a Klaviyo segment to an existing Pinterest audience that already contains profiles, these profiles are not deleted. Klaviyo adds its profiles to the existing members of the audience. To avoid mixing, always create new Pinterest audiences for your Klaviyo synchronizations.
Advanced use cases to maximize ROI
Intelligent Retargeting
Sophisticated abandoned carts
Instead of retargeting all abandoned carts the same way, create specific Klaviyo segments based on cart value, products involved, or abandonment time. An abandoned cart of €500 deserves different advertising treatment than a €50 cart.
Synchronize these segments to distinct Pinterest audiences with adapted creatives. For large carts, use premium visuals and reassurance messages. For small carts, focus on urgency and additional incentives.
Differentiated win-back strategies
Segment your inactive customers based on their historical value and inactivity period. A VIP customer inactive for 3 months requires a different approach than a casual customer inactive for 6 months.
Create corresponding Pinterest audiences with tailor-made campaigns: exclusive new arrivals for VIPs, bestsellers and trends for casual customers. This personalization significantly improves reactivation rates.
Targeted cross-sell and upsell
Leverage purchase history in Klaviyo to create customer segments who have purchased specific products. Synchronize these segments to Pinterest to promote complementary products or higher-end ranges.
A customer who bought a camera will see ads for lenses and accessories. A cosmetics buyer will discover your brand's makeup range. This cross-sell approach often generates higher ROAS than general targeting.
Optimized Acquisition
High-performing lookalike audiences
Identify your segment of best customers in Klaviyo (high lifetime value, frequent purchases, high engagement) and synchronize it to Pinterest. Then use this audience as a base to create lookalike audiences on Pinterest.
These lookalike audiences based on your first-party data generally perform better than those created solely from the Pinterest pixel. They capture the deep behavioral characteristics of your best customers.
Strategic exclusions to optimize budget
Create smart exclusion segments in Klaviyo: recent buyers, customers with open support tickets, disengaged subscribers, or unprofitable geographic segments. Synchronize these exclusions to Pinterest to focus your budget on qualified prospects.
This approach can reduce your acquisition costs by 20-30% by avoiding waste on non-converting profiles.
Sophisticated cross-channel strategies
Coordinated sequences
Orchestrate your Klaviyo and Pinterest communications to create seamless cross-channel journeys. A prospect who receives a lead magnet email in Klaviyo can see a reminder Pinterest ad 24 hours later.
This coordination strengthens the impact of your messages and improves brand recall. Prospects exposed on multiple channels generally convert 2-3 times better.
Channel receptivity testing
Compare the performance of your segments by channel: some segments respond better to email, others to social advertising. These insights guide your future budget allocation between Klaviyo and Pinterest.
A segment of impulsive buyers may react better to visual Pinterest ads, while a segment of thoughtful customers prefers detailed Klaviyo emails.
Optimization and best practices
Maximizing integration efficiency
Rigorous audience organization
Adopt a systematic naming convention for your synchronized Pinterest audiences. Use prefixes like "KL_" followed by the segment name and creation date: "KL_AbandonedCart_Nov2024". This organization facilitates management and avoids confusion.
Document your connections in a summary table: Klaviyo segment, corresponding Pinterest audience, campaign objective, and observed performance. This documentation helps with continuous optimization and facilitates team handovers.
Regularly clean up your obsolete audiences. An unsuccessfully tested segment clutters your Pinterest interface and can create unintentional targeting errors.
Structured testing strategies
Systematically test your synchronized Klaviyo audiences against standard Pinterest targeting. Create mirrored campaigns with equivalent budgets to measure the actual impact of your first-party data.
Start with your most obvious segments: recent abandoned carts, VIP customers, or high-intent visitors. These segments generally show the most significant performance differences and justify the investment in integration.
Vary your creatives according to the targeted segment. A VIP segment deserves premium visuals and exclusive messages, while a discovery segment requires informative and reassuring creatives.
Continuous monitoring and adjustments
Key metrics to monitor
Track the match rate between your Klaviyo segments and Pinterest audiences. A low rate may indicate a discrepancy between your customer base and the Pinterest audience, requiring a strategy adjustment.
Measure ROAS per synchronized audience and compare it to your standard Pinterest campaigns. This metric justifies the investment in integration and guides your future optimizations.
Analyze the evolution of your synchronized audience sizes. A shrinking audience may indicate a performance problem with your source segment in Klaviyo.
Klaviyo-Pinterest correlations
Cross-reference your Pinterest performance data with Klaviyo engagement metrics. Do segments that perform well in email also perform well in Pinterest advertising? These correlations guide your budget allocation strategy.
Monitor for halo effects: Do your Pinterest campaigns targeting Klaviyo segments impact the email engagement of those same segments? This cross-channel synergy often justifies higher ad budgets.
Troubleshooting and Solutions
Resolving Common Issues
Empty or Partially Populated Audiences
If your Pinterest audiences remain empty after 48 hours, first check the size and quality of your source Klaviyo segment. A segment with fewer than 100 profiles may not generate enough Pinterest matches to create a viable audience.
Check the quality of the emails in your segment. Invalid, temporary, or professional emails (B2B domains) are less likely to have an associated Pinterest account. Clean your Klaviyo segments to improve match rates.
Also, check the geography of your segment. Pinterest has varying penetration depending on the country. A segment concentrated in markets where Pinterest is little used will naturally have a low match rate.
Synchronization Problems
If your audiences do not update after modifying Klaviyo segments, check the permissions of your Pinterest connection. Rights may expire or be unintentionally revoked during organizational changes.
Test the connection by creating a small test segment in Klaviyo and verifying its synchronization to Pinterest. This approach isolates technical issues from audience matching issues.
Permission and Access Errors
Permission errors often occur during team changes or reorganizations. Ensure that the user who set up the integration retains their Pinterest and Klaviyo administrator rights.
If you change your Pinterest ad account, you will need to completely reconfigure the integration. Prepare for this transition by documenting your current configurations and planning a migration period.
Preventative Best Practices
Always test your new configurations with small segments before deploying them at scale. This approach limits risks and allows for quick identification of potential problems.
Document your integration configurations and share this documentation with your team. In case of a problem, up-to-date documentation significantly speeds up resolution.
Schedule a monthly check of your synchronizations. Regular monitoring helps detect drifts before they impact your advertising performance.
