Create reorder links that automatically pre-fill checkout with the customer’s shipping details and add items from their previous purchase - perfect for replenishment flows.
Why Use Reorder Links
A reorder link removes all friction from repeat purchases. When a customer clicks your link, they get:
- Pre-filled checkout - Name, email, and shipping address already entered
- Previous order items - Products from their last purchase added to cart
- Optional promotions - Discounts, free shipping, or gifts to incentivize the reorder
This works great for replenishment flows and subscription alternatives.
Quick Setup
Replace [customerId] in your link with this Klaviyo variable:
{{ person.id|default:'' }}
Your final link:
https://yourstore.com/reorder?c={{ person.id|default:'' }}
Create Your Reorder Link
Create a new link
Go to Checkout Links and click Create Link.
Name your link
Give it a descriptive name like “Reorder Link” or “Replenishment Flow”.
Set a custom slug
Enter a custom slug such as reorder or replenish.
Enable Dynamic mode
Toggle on Dynamic to enable customer data loading via URL parameters.
Enable reorder items
In the Cart card, check the Reorder items checkbox. This will automatically add items from the customer’s previous order.
You can add promotions to incentivize reorders:
- Free shipping - Always a good incentive for repeat customers
- Percentage discount - Reward loyalty with 10-15% off
- Free gift - Add a sample or bonus item
With tiered promotions, you can offer different incentives based on reorder value:
| Reorder Value | Offer |
|---|
| Up to $50 | Free shipping |
| $50 - $100 | Free shipping + 10% off |
| $100+ | Free shipping + 10% off + free gift |
Higher-value reorders are already profitable - you might skip discounts for large carts and only incentivize smaller ones.
Combine with Pre-checkout extensions to let customers modify their cart before checkout - great for fashion brands where customers might need to change sizes, or for adding optional upsells.

Copy the URL
Copy the link URL. It will look something like:https://yourstore.com/reorder?c=[customerId]
Add the Link to Your Klaviyo Flow
Open your replenishment flow
In Klaviyo, navigate to your replenishment flow. If you don’t have one, browse Klaviyo’s flow library for templates.
Edit your email template
Open the email template you want to add the reorder link to.
Find your call-to-action button
Locate the CTA button (e.g., “Reorder now” or “Buy again”).
Replace the link URL
Paste your Checkout Links URL into the button link field.
Add the Klaviyo variable
Replace [customerId] with this Klaviyo variable:{{ person.id|default:'' }}
Your final link will look like:https://yourstore.com/reorder?c={{ person.id|default:'' }}
This uses the Klaviyo person ID, which is always available on every profile. If you have Shopify customer IDs synced to Klaviyo, you could use those instead, but the person ID is more reliable.
