How it works

2 steps to start adding fulfilled order customers to your Klaviyo list automatically

App connector: Shopify • Time to complete: 0 minutes (Auto-configured)

Why this matters: This trigger captures the perfect moment when customers have received their products and are most receptive to follow-up communications, review requests, and repeat purchase offers.

When an order is marked as fulfilled in Shopify, this trigger activates the workflow and captures the customer's contact information including {{shopify.email}} and {{shopify.phone}}. The workflow runs for every order fulfillment in your store, ensuring no customer is missed for post-purchase engagement.

App connector: Klaviyo • Time to complete: 3 minutes

Why this matters: Automatically segments fulfilled-order customers into a dedicated list, enabling you to send targeted post-purchase campaigns without manually managing list membership or risking missed follow-ups.

This step adds the customer's profile to your specified Klaviyo list using either {{shopify.email}} or {{shopify.phone}} as the identifier. The workflow passes the customer data to Klaviyo's profile system, which either updates an existing profile or creates a new one before adding them to the list. You'll need to configure the list ID (found in your Klaviyo account under Lists > List Settings > API ID).

Frequently asked questions

What happens if a customer is already on the Klaviyo list?

Klaviyo automatically handles duplicates—if the customer profile already exists in the list, it simply updates their information rather than creating a duplicate entry. The workflow can run multiple times for the same customer without issues.

Can I add customers to multiple Klaviyo lists at once?

Yes, duplicate the "Add Profile to List" step and configure each copy with a different list ID. The workflow will add the customer to all specified lists simultaneously after fulfillment.

Does this work for partially fulfilled orders?

Yes, the "Order Fulfilled" trigger activates when an order is marked as fulfilled, including partial fulfillments. If you want to wait until all items are fulfilled, you'll need to add a Filter step to check if all line items have been fulfilled before adding to the list.

Customize this workflow even further:

Route customers to different lists based on order value

Add conditional paths that check the order total and send high-value customers to a VIP list while standard orders go to your general post-purchase list.

Include product-specific information

Pass product names, SKUs, or categories from the fulfilled order to Klaviyo as custom properties, enabling product-specific review requests or cross-sell campaigns.

Set delays before adding to the list

Add a delay step before the Klaviyo action to wait 2-3 days after fulfillment, timing your list addition with estimated delivery dates for more relevant follow-up timing.

Track in Google Sheets for reporting

Connect a Google Sheets step to log each fulfillment with customer email, order number, and timestamp, creating an audit trail of your post-fulfillment marketing automation.
