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.
This guide requires Klaviyo to be connected via Checkout Links.
See Setting up Klaviyo integration first.
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
reorderorreplenishEnable 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
Add Promotions (Optional)
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 pages 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 Your Link
Save your link — Click Save to create your reorder link
Copy the 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.
