InPost Lockers and Klaviyo

Integration Agency & Consultants

Operational pressure mounts when marketing automation ignores the physical location of the order. At scale, sending a generic review request while a parcel is still sitting in an InPost locker creates customer friction and damages brand trust. We connect InPost locker events directly to Klaviyo events so that your messaging acknowledges the genuine parcel status. Moving from dispatch based triggers to collection based triggers ensures your post purchase journey reflects the reality of the locker experience.

Solution Design

Our design for the InPost and Klaviyo integration treats granular locker events, like parcel arrival and collection, as the primary triggers for post purchase flows. In this model, the locker system acts as the source of truth for location status, while Klaviyo manages the communication logic. A key design decision involves the trade-off between real-time event triggers and scheduled polling for updates. We typically prioritise event based triggers for collection alerts to ensure timely customer action, while using defined intervals for non-urgent status updates to protect system stability. This choice accepts slight operational latency on secondary data to ensure the critical collection window is hit accurately. This ensures CX teams see a customer profile updated by physical behaviour, allowing operations to track successful fulfilment based on actual collection rather than just carrier handover.

Synchronising parcel movements with customer profiles

The integration synchronises granular InPost locker events, including arrival, deposit, and collection, directly into Klaviyo customer profiles. InPost remains the source of truth for all physical parcel movements, ensuring that marketing flows are triggered by real-world events. You can use these timestamps to automate specific reminders, such as notifying a customer when a parcel has exceeded the standard collection window. Monitoring is embedded to detect delays in event processing, preventing communications from becoming irrelevant. This connection allows your marketing automation to use precise location and status data to drive engagement without the need for manual CSV exports.

Orchestration through secure integration platforms

Cogent2 leverages IPaaS to integrate InPost Lockers and Klaviyo with Smart Lockers and ESPs securely. IPaaS platforms, with ISO 27001 and SOC 2 compliance and above, ensure data security and efficient operations. This integration facilitates InPost Lockers and Klaviyo connections, enhancing Smart Lockers and ESP functionalities, while maintaining high security standards.

Monitoring sync health and event accuracy

Standard dashboards often fail to alert you when a physical locker event misses its digital counterpart in Klaviyo. Real visibility requires monitoring the specific link between locker updates, such as arrival or collection, and the resulting flow triggers. Undetected sync delays or mapping errors cause customers to receive reminders for parcels they have already collected, which quickly erodes brand credibility. We surface these operational discrepancies early, ensuring your monitoring focuses on the customer's actual experience rather than just the technical success of a data transfer. Proper visibility aligns the digital notification with the physical parcel journey.

Operational handover for internal ecommerce teams

The ecommerce, CX, and operations teams must own the integration logic to prevent communication drift. Training covers the specific InPost and Klaviyo operating model, ensuring teams know where locker event data resides and how to verify sync health daily. We define which checks CX should perform to confirm collection reminders are triggering correctly and how to handle delivery exceptions before they reach the helpdesk. Handover documentation is provided as a practical operational reference, focusing on the business logic rather than technical theory. This ensures your team can confidently manage the post-purchase journey and understand how granular locker events drive customer engagement.

Governance and reporting of delivery exceptions

Support prioritises the ongoing integrity of the event data flowing between InPost and Klaviyo. This involves monitoring for missed events or sync delays that could lead to irrelevant customer notifications. We provide clear escalation paths for operational exceptions, helping your team distinguish between a carrier delay and an integration failure. This ensures that as parcel volumes grow, your automated communications remain grounded in real-time delivery status rather than static assumptions. Our focus is on maintaining the trust your customers place in your post-purchase updates.

Integration operating model

The operating model treats InPost locker events as the authoritative trigger for Klaviyo automated flows. When a parcel is deposited into a locker, a 'Ready for Collection' event is pushed to the customer profile to initiate the notification sequence. If the parcel remains uncollected, the integration typically triggers staggered reminders based on the time elapsed since the initial drop-off. Once the locker system registers a collection, the status updates in Klaviyo to terminate reminder flows and initiate post-purchase engagement like review requests. This relies on InPost being the source of truth for delivery status, ensuring your teams do not need to manually check parcel tracking to manage customer communications.

Common failures

Premature 'Ready for Collection' notifications.

Operational impact: Customers travel to a locker only to find their parcel is not there, creating a significant negative experience. This drives 'where is my order?' contacts to the customer service team and erodes trust in all delivery communications. The failure directly undermines the convenience proposition of using a locker service.

Prevention / Action: The integration logic must be sequenced so the Klaviyo 'Ready for Collection' event is triggered only by the specific InPost API status confirming the parcel is scanned into the destination locker. Do not use an earlier status like 'Dispatched' or 'Out for Delivery' from the warehouse management system for this trigger. This discipline ensures the marketing message always reflects the physical reality at the locker.

Missing or invalid customer phone numbers.

Operational impact: An invalid mobile number on the Sales Order prevents the InPost system from creating a shipment or sending SMS updates. The fulfilment process for that order halts, requiring manual intervention from the operations team to locate the customer, update the customer record, and re-process the shipment. This introduces shipping delays and adds direct labour cost to order processing.

Prevention / Action: Implement strict validation on the phone number field during the ecommerce checkout, using format rules specific to the shipping country. The integration itself should treat an invalid number as an exception, holding the order in a dedicated queue for review by the customer service team. This prevents failed API calls and contains the exception for a defined operational process to resolve.

Delayed synchronisation of collection events.

Operational impact: When the 'Parcel Collected' status from InPost is slow to update in Klaviyo, marketing automation becomes misaligned with the customer journey. For example, a product review request may be sent before the customer has the item, or a re-engagement flow could be triggered for a customer who has just collected their order. This damages brand perception and makes marketing efforts feel clumsy and unresponsive.

Prevention / Action: Use webhooks from InPost as the primary mechanism for receiving status updates, as this provides the most immediate data. If polling the API is necessary, the schedule must be frequent enough to support the intended marketing cadence. Monitor the processing queue between the InPost webhook receiver and the Klaviyo API to ensure events are not getting stuck during high-volume periods.

Generic returns messaging for locker orders.

Operational impact: Standard returns instructions, triggered from a generic Klaviyo template, create confusion for customers who received their order via a locker. This results in avoidable contacts to the customer service team asking how to start a return. The friction can also delay the return reaching the warehouse, impacting stock availability and the timing of financial refund journals.

Prevention / Action: The original delivery method from the Sales Order must be stored as a custom property against the customer profile in Klaviyo. Use this property to create an 'InPost Customer' segment. All returns-related communication for this segment must be routed through a dedicated Klaviyo flow that provides clear, specific instructions for the InPost locker returns process.

Frequently asked questions

How does this integration differ from the standard 'Order Fulfilled' email in Klaviyo?

Standard Klaviyo triggers fire once when an order's fulfilment is created in Shopify, which is often before the parcel has even been dispatched. This integration uses multiple, real-world events directly from the InPost system, such as 'Parcel at Locker' or 'Collection Reminder'. This allows you to create specific, timely Klaviyo flows that accurately reflect the parcel's journey, rather than sending a single, generic 'shipped' notification.

What happens if a customer's phone number is missing or wrong on their order?

An incorrect or missing phone number on the customer record or order in Shopify will cause the InPost dispatch to fail with an API error. Because InPost cannot create the shipment, no delivery events are generated. As a result, no data can be sent to Klaviyo to trigger your parcel tracking flows, leaving the customer without any updates at all.

How does this integration affect our warehouse and fulfilment process?

Your fulfilment process must adapt to wait for confirmation of a locker selection from the InPost system before marking an order as fulfilled. If a Shopify order is fulfilled before InPost provides the 'parcel_target_id' for the chosen locker, no label can be generated. This breaks the process, and no subsequent delivery status events, like 'Dispatched' or 'In Transit', will be available to trigger workflows in Klaviyo.

Can we stop customers choosing lockers for oversized items?

Yes, filtering out InPost as a shipping option for certain SKUs is a vital part of a successful setup. Products that exceed InPost's size or weight limits must be identified in Shopify so the locker option can be hidden at checkout. Failing to do this leads to failed orders that cannot be fulfilled, creating a poor customer experience and requiring manual clean-up from your customer service team.

Why should we use Klaviyo for delivery updates if InPost already sends SMS notifications?

Relying purely on the courier's own SMS messages means you lose control over the post-purchase brand experience and the associated data. By syncing InPost events to Klaviyo, your marketing team can build and measure branded email flows that guide the customer to their locker. This turns a simple operational update into a rich, brand-owned communication channel that can support future marketing campaigns.
