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:'' }}
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.
- 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
Common mistake: Do NOT create a separate link for each tier. You configure all tiers on a single link. Checkout Links automatically applies the right tier based on the reorder value at checkout.
How It Works
You create one reorder link and add multiple promotion tiers to it. When a customer clicks the link in your Klaviyo email, their previous order items are loaded via the ?c= parameter. Checkout Links evaluates the cart total and automatically applies the matching tier’s promotions — no separate links needed.
Setting Up Tiers
Enable Promotions
In your link editor, toggle on the Promotions section.
Add your first tier's promotions
Click Add discount and select your promotion type (e.g., free shipping).
Set a threshold condition
Change the condition from No threshold to Cart total.
Set the value range
Enter the minimum and maximum values for this tier. For example, $0 to $50.
Add another tier
Click Add promotion to create a new tier. Set a higher threshold range and add different promotions.
Repeat for additional tiers
Continue adding tiers until you’ve covered all reorder value ranges. Higher tiers typically get better offers.
Example Configuration
All of these tiers are configured on one link:
| Reorder Value | Offer |
|---|
| Up to $50 | Free shipping |
| $50 – $150 | Free shipping + 10% off |
| $150 – $300 | Free shipping + 15% off + free gift |
| $300+ | Free shipping only (no percentage discount) |
Consider adding a ceiling tier for high-value reorders. You probably don’t want to give 15% off a $500 order — set a top tier that offers free shipping only, or a smaller flat discount. Higher-value reorders are already profitable, so protect your margins.
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 Your Link
Save your link
Click Save to create your reorder link.
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:'' }}
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.
Test Your Flow
Save your template
Save your changes in Klaviyo.
Send a test email
Use Klaviyo’s preview and test feature. Select a customer profile that has a previous order.
Click the CTA button
Open the test email and click your reorder button.
Verify the checkout
Confirm that:
- Customer details are pre-filled (name, email, shipping address)
- Items from their previous order are in the cart
- Any promotions you configured are applied
