Delivery represents a key moment in the e-commerce customer experience. 70% of customers want to be informed in real time about the status of their order, and proactive communication about delivery improves satisfaction by 40%. Yet, many e-retailers neglect this crucial step in the customer journey.
Between order confirmation and package receipt, your customers experience a waiting period that can generate anxiety or, conversely, strengthen their trust in your brand. The difference lies in the quality of your communication during this phase.
The ShipStation-Klaviyo integration transforms your logistics data into marketing opportunities. Instead of leaving your customers in uncertainty, you automate personalized communication for each delivery stage. This approach reduces customer service requests while creating new sales opportunities.
In this guide, you will discover how to set up this integration in 15 minutes, leverage the 5 synchronized order statuses to create automated flows, and transform your delivery emails into growth drivers.
Why connect ShipStation to Klaviyo?
Transforming your logistics data into marketing opportunities
The ShipStation-Klaviyo integration goes far beyond simple delivery notification. It automatically synchronizes 5 different order statuses every 30 minutes, creating targeted communication opportunities throughout the logistics process.
This wealth of data allows you to segment your customers based on their delivery behaviors. You can identify customers who often have pending payment orders, those who frequently cancel, or those who regularly order out-of-stock products.
Immediate operational benefits: The automatic synchronization eliminates manual work of updating statuses in Klaviyo. Your customer service teams see their workload decrease thanks to proactive notifications that answer questions before they are asked.
The last 90 days of history are automatically synchronized upon installation, giving you an immediate comprehensive view of your delivery patterns to optimize your future communications.
New marketing opportunities: Each order status becomes a trigger for relevant marketing actions. A shipped order can trigger recommendations for complementary products. A pending order can motivate an additional purchase to optimize shipping costs.
This approach transforms potentially negative moments (delays, waiting) into opportunities to strengthen customer relationships and generate additional revenue.
Concrete use cases that generate results
Automatic payment recovery: Pending payment orders automatically trigger personalized reminder sequences. Instead of losing these sales, you guide the customer to completion with messages adapted to their situation.
Smart cross-selling during delivery: A shipped order becomes an opportunity to suggest complementary products with perfect timing: the customer is satisfied with their purchase and receptive to new suggestions before receiving their package.
Proactive support for problematic situations: Orders put on hold (out of stock, payment issue) trigger proactive communication explaining the situation and offering alternatives, preventing frustration and cancellations.
Technical and business prerequisites
What to check before integration
Mandatory ShipStation prerequisites: This integration requires a ShipStation Scale Gold or Accelerate subscription as it uses the V1 API. Lower plans do not provide access to the API functionalities required for synchronization with Klaviyo.
Verify that you have administrator rights to your ShipStation account. Generating API keys and configuring permissions require these privileges. If you work with a team, coordinate with the main account administrator.
Ensure you have a sufficient volume of orders to justify automation. This integration brings the most value to e-retailers processing at least 50-100 orders per month, a threshold where automation becomes truly cost-effective.
Klaviyo side preparation: Your Klaviyo account must already be integrated with your main e-commerce platform (Shopify, WooCommerce, etc.). The ShipStation integration complements this data by adding the logistics dimension, but does not replace the basic e-commerce integration.
Define your post-purchase email strategy before integration. What messages do you want to send for each status? How often? This prior reflection accelerates implementation and improves results.
Prepare your delivery email templates. Klaviyo will provide the data, but you need to create templates that match your brand identity and marketing objectives.
Important constraints to anticipate
The integration initially synchronizes the last 90 days of ShipStation data. For accounts with older history, this limitation may create a delay before having a complete view of customer patterns.
Synchronization occurs every 30 minutes, not in real time. For ultra-reactive communications, this delay may require adjustments in your expectations and flow configuration.
Klaviyo's geographic availability is currently limited to the United States, United Kingdom, Canada, Australia, and New Zealand. Check this compatibility based on your main market.
Step-by-step configuration
Integration in 15 minutes
Generating ShipStation API keys
Step 1: Access API settings: Log in to your ShipStation account and click on the gear icon to access account settings. In the side menu, select “Account” then “API Settings”.
Step 2: Generate V1 API key: In the API Settings section, select “V1 API” from the dropdown menu. This version is mandatory for Klaviyo integration. Click “Generate API Key” to start the process.
ShipStation sends a verification email to your address. Click on the verification link, then return to the interface to click “Generate API Key” again once verification is confirmed.
Step 3: Configure expiration: Choose the validity period for your API key: 3, 6, or 12 months. To avoid service interruptions, schedule a renewal reminder before expiration. Click “Generate” to definitively create your key.
Step 4: Save credentials: Immediately copy your API key and secret. ShipStation only displays them once during generation. Store them securely, for example, in a team password manager.
Configuration in Klaviyo
Step 5: Install the integration: In your Klaviyo account, click on the “Integrations” tab then “Add integrations”. Search for “ShipStation” in the list of available integrations and click on the corresponding card.
Click “Install” to start the installation process. Klaviyo prepares the ShipStation-specific configuration interface.
Step 6: Configure the connection: Enter the API key and API secret generated in ShipStation into the corresponding fields. Carefully check the entry as any error will prevent the connection.
Click “Connect to ShipStation” to establish the link between the two platforms. Klaviyo automatically tests the validity of your credentials.
Step 7: Authorize permissions: Review the list of permissions Klaviyo requests to access your ShipStation data. These permissions include reading order statuses and delivery information. Click “Allow” to finalize the authorization.
A success message confirms that the integration is now active and synchronization will begin.
Verification of proper functioning
Step 8: Check initial synchronization: Go to “Analytics” > “Metrics” in Klaviyo. Select “All Integrations” then “ShipStation” to filter by metrics synchronized from ShipStation.
Click on a metric like “Order Awaiting Shipment” then on the “Activity Feed” icon to see events being synchronized.
Step 9: Verify data consistency: Compare the number of orders shipped in Klaviyo with your ShipStation data for the same period. Navigate to the “Order Shipped” metric and examine the previous day's data.
If the numbers do not match, check the consistency of time zones between your two accounts. In Klaviyo, go to “Settings” > “Organization” to check the configured time zone.
Step 10: Test with recent orders: Use a recent order to test synchronization. Change its status in ShipStation and verify that the change appears in Klaviyo within the next 30 minutes.
This verification confirms that the integration is working correctly and you can start creating your automated flows.
Understanding synchronized metrics
5 statuses to optimize your customer communication
The ShipStation-Klaviyo integration synchronizes five main metrics, each corresponding to a specific stage of the delivery process. Understanding these statuses allows you to create relevant communications for each situation.
Order Awaiting Shipment
This metric triggers when an order is ready to be shipped in ShipStation. Payment is validated, products are available, but the shipping label has not yet been generated.
Marketing opportunities: This is the ideal time for last-minute upsell communications. Offer complementary products with arguments like "Add this to your order before shipping" or "Optimize your shipping costs with these items."
Expectation management: Proactively inform about estimated shipping times. This transparency reduces customer anxiety and customer service requests.
Advanced personalization: Adapt your messages based on order value or product type. A large order deserves special attention with information on careful packaging or priority delivery.
Order Awaiting Payment
This status concerns unpaid orders marked as pending payment in ShipStation. Not all e-commerce systems support unpaid orders, but this feature is valuable for certain business models.
Automating reminders: Create personalized reminder sequences based on the elapsed time. First reminder after 24 hours with an informative tone, second reminder after 48 hours with a sense of urgency, third after 72 hours with an offer of assistance.
Segmenting issues: Identify customers who regularly have payment problems to adapt your future sales approach or offer other payment methods.
Preventing abandonments: Offer proactive assistance to resolve payment issues rather than waiting for the customer to abandon their order.
Order On Hold
This metric activates when you use ShipStation's "Hold" function to temporarily suspend an order. Reasons include out-of-stock items, pre-orders, or security verifications.
Proactive communication: Immediately inform the customer of the situation and estimated delays. This transparency transforms a potential point of friction into an opportunity to build trust.
Managing stockouts: Offer alternatives or pre-orders for out-of-stock products. Maintain customer engagement even when you cannot deliver immediately.
Behavioral segmentation: Identify customers who frequently order out-of-stock products to alert them first during restocks.
Order Shipped
This status triggers as soon as a shipping label is generated in ShipStation. This is often the moment customers anticipate most and an excellent marketing opportunity.
Confirmation and tracking: Immediately send tracking information with an attractive design that enhances the excitement of upcoming receipt.
Strategic cross-sell: Take advantage of post-purchase satisfaction to offer complementary products. The timing is perfect as the customer is happy with their purchase and receptive to new suggestions.
Post-delivery preparation: Announce your loyalty programs, request product reviews, or offer exclusive content to maintain engagement beyond delivery.
Order Cancelled
This metric tracks orders cancelled in ShipStation, whether customer cancellations or technical cancellations.
Smart recovery: Analyze cancellation reasons to offer appropriate alternatives. An out-of-stock cancellation calls for a different solution than a change-of-mind cancellation.
Pattern analysis: Identify products or periods with high cancellation rates to adjust your sales strategy or logistics processes.
Personalized winback: Create adapted recovery campaigns based on customer history and probable cancellation motivations.
Advanced automation strategies
Leveraging delivery data to generate more revenue
The ShipStation-Klaviyo integration opens up automation possibilities that go far beyond simple status notifications. By intelligently leveraging this data, you create personalized customer experiences that generate additional revenue.
Flows based on delivery statuses
Sophisticated communication sequences: Create multi-stage flows triggered by each status. For an "Awaiting Shipment" order, first send a preparation confirmation, then 24 hours later an upsell proposal, and finally an imminent shipping notification.
This sequential approach maintains engagement without being intrusive. Each email provides specific value: information, opportunity, or reassurance.
Optimal communication timing: Analyze your data to identify the most effective sending slots for each status. Shipping confirmations often perform better at the end of the day when customers check their personal emails.
Upsell proposals for orders under preparation work better in the middle of the week when attention is more sustained.
Escalation based on delays: Configure automatic escalations when statuses remain stagnant abnormally. An order "Awaiting Payment" for more than 48 hours triggers a support communication. An order "On Hold" for more than a week activates an alternative proposal.
Advanced behavioral segmentation
Customer profiles based on delivery habits: Create segments based on delivery patterns: customers who often order express, customers who frequently cancel, customers who regularly have payment issues.
These segments allow for in-depth personalization of your future commercial communications. A customer accustomed to express deliveries will appreciate premium products, while a customer sensitive to delays will prefer detailed information on stock.
Problematic order history: Identify customers who have a history of orders on hold or cancelled. Adapt your commercial approach by offering enhanced guarantees, flexible payment options, or priority customer service.
Inferred communication preferences: Analyze open and click-through rates based on types of delivery emails to infer each customer's preferences. Some prefer factual information, others commercial proposals, still others branded content.
Contextual cross-sell and upsell opportunities
Recommendations during the waiting period: An order being prepared or in transit offers an opportunity to propose complementary products with grouped delivery. Analyze frequent product associations for relevant suggestions.
Targeted post-delivery offers: As soon as shipping is confirmed, launch recommendation sequences based on purchase history and seasonal trends. Post-purchase timing optimizes receptiveness.
Loyalty programs based on logistics history: Reward customers who never cancel, always pay quickly, or order regularly. These positive logistical behaviors deserve recognition and incentives to continue.
Optimization and monitoring
Measuring and improving impact
Implementing the integration is just the beginning. Continuous optimization of your delivery communications generates significant long-term performance improvements.
Key metrics to monitor
Performance by order status: Measure open and click-through rates for each type of delivery email. Shipping confirmations typically have high open rates (60-80%) but variable click-through rates depending on the relevance of the included offers.
Emails for pending orders often show average open rates but high conversion rates because they target customers already engaged in a purchase process.
Impact on customer service: Track changes in the volume of order tracking inquiries. Successful integration reduces these inquiries by 30-50% thanks to proactive notifications.
Also measure post-delivery customer satisfaction via surveys or product reviews. Transparent communication generally improves satisfaction scores.
Additional revenue generation: Calculate the revenue attributable to delivery emails, particularly upsells on orders in preparation and cross-sells post-shipment. These additional revenues largely justify the investment in integration.
Continuous optimizations
A/B testing of messages by status: Test different approaches for each communication type: informative vs. commercial tone, product vs. experience focus, short vs. detailed messages.
These tests often reveal preferences specific to your audience and industry. Luxury brands perform better with elaborate messages, while practical brands prefer conciseness.
Personalization based on history: Adapt your messages based on each customer's past behavior. A customer who has previously experienced delayed orders will appreciate more detailed information on delivery times. A regular buyer can receive exclusive VIP offers.
Adjusting send timings: Analyze performance by send time and day to optimize your communication schedule. Shipping notifications often perform better in the evening, while commercial propositions prefer daytime slots.
Evolution towards an omnichannel strategy
The ShipStation-Klaviyo integration is part of a broader marketing approach. Coordinate these communications with your other channels: SMS for urgent notifications, push notifications for mobile customers, advertising remarketing for canceled orders.
This omnichannel coordination amplifies the impact of each message and creates a consistent customer experience across all touchpoints.
Conclusion
The ShipStation-Klaviyo integration transforms your logistical processes into powerful marketing levers. Instead of enduring delivery constraints, you leverage them to create added value and strengthen customer relationships.
The benefits are quickly measured across three dimensions. Improved customer experience leads to increased satisfaction and more positive reviews. Reduced support workload frees up resources for higher-value tasks. New revenue opportunities through upsell and cross-sell largely offset the initial investment.
The key to success lies in a progressive approach. Start by automating basic communications for each status, then gradually enrich them with commercial offers and advanced personalizations. This controlled evolution allows you to optimize performance without risking over-soliciting your customers.
Remember that this integration is part of a larger marketing ecosystem. Coordinate your delivery communications with your other Klaviyo campaigns to maintain consistency in your customer relationships. This holistic approach maximizes the impact of each touchpoint.
Your ShipStation-Klaviyo integration is now operational. Configure your first automated flows, monitor performance, and progressively optimize to turn every delivery into a growth opportunity.
