How to Use Klaviyo Checkout Links to Personalize Shopify Email Campaigns

Every Klaviyo email you send has a CTA. Most of those CTAs point to a product page. The customer clicks, browses, adds to cart, enters a discount code, and checks out. That's five steps. Each one is a drop-off point.

Checkout Links removes all of them. You build a URL with the exact products, quantities, variants, and discounts pre-loaded. Drop it into any Klaviyo flow or campaign. When the customer clicks, they land on a Shopify checkout page with everything already in their cart. One click to buy.

That's the difference between a generic email and a personalized one. Not different subject lines. Not swapping a first name into the header. Actual personalization — where every recipient gets a checkout experience built for them.

What Klaviyo + Checkout Links Actually Does

Checkout Links connects to Klaviyo through a native OAuth integration. You link your Klaviyo account from inside the Checkout Links app — no API keys to copy, no webhooks to configure. Once connected, Checkout Links can trigger Klaviyo flows and sync event data automatically.

Here's what that means in practice:

Dynamic checkout URLs. Each checkout link is a URL that pre-loads a Shopify checkout with specific products, variants, quantities, and discounts. You paste these URLs into your Klaviyo email templates as buttons or text links.

Pre-applied discounts. No more "use code SAVE15 at checkout." The discount is baked into the link. The customer clicks and sees the discounted price immediately. No code to remember, no field to find.

Full attribution. Every click on a checkout link is tracked. You can see which Klaviyo flow generated which sales, down to the individual link. No UTM guesswork.

One-click checkout. Returning customers with Shop Pay or accelerated checkout enabled can complete their purchase in a single tap. The cart is pre-filled, the discount is applied, and their payment info is saved. That's a conversion path measured in seconds, not minutes.

5 Klaviyo Flows That Convert Better With Checkout Links

You can use checkout links in any Klaviyo email. But these five flows see the biggest improvement because they target customers who already have intent — they just need the friction removed.

1. Abandoned Cart Recovery

Standard abandoned cart emails say "you left something behind" and link to the store. The customer has to find the product again, add it to cart again, and check out.

With Checkout Links, the abandoned cart email contains a link that restores the exact cart they left behind. Same products, same variants, same quantities. Add a 10% discount to sweeten the deal and it's pre-applied — no code entry. The customer clicks once and they're back at checkout, ready to pay.

Checkout Links has a dedicated abandoned cart setup flow. Connect Klaviyo, and the app generates dynamic cart-recovery links that sync with your existing Klaviyo abandoned cart flow.

2. Post-Purchase Cross-Sell

A customer buys running shoes. Three days later, they get a Klaviyo email with a checkout link for running socks and insoles — pre-loaded at a 15% bundle discount.

This works because you're not asking them to browse. You're not asking them to decide. You're handing them a curated offer that complements what they already bought. The checkout link skips every step between "that looks good" and "purchased."

3. Win-Back Campaign

A customer hasn't ordered in 90 days. Your win-back flow sends an email with a checkout link to their most-purchased product, plus a 20% "we miss you" discount baked in.

Generic win-back emails send customers to your homepage and hope they remember what they liked. A checkout link sends them straight to a pre-filled checkout with the product they actually want. That's the difference between a 2% and a 10% re-engagement rate.

4. VIP Exclusive Access

Segment your top 10% of customers in Klaviyo. Send them a checkout link to a new product before it goes live on your store — with a VIP-only price applied automatically.

This turns email into a private sales channel. The checkout link is the storefront. No landing page needed, no early access password, no coupon code. Just a link that gives your best customers first access at a better price.

5. Welcome Series First-Purchase Offer

New subscriber signs up. Your Klaviyo welcome flow sends a checkout link with your best-selling product and a first-purchase discount pre-loaded.

Most welcome emails send people to the homepage and pray. A checkout link removes the entire discovery step. The new subscriber gets a curated offer with a discount already applied. They tap and buy. That's how you turn a 2% welcome flow conversion rate into something worth measuring.

How to Set It Up

You need a Checkout Links subscription ($25/mo) and a Klaviyo account. Setup takes about 10 minutes.

Step 1: Connect Klaviyo

In the Checkout Links app, go to Settings and click Connect Klaviyo. You'll authorize the connection through Klaviyo's OAuth flow — just click Allow. No API keys, no manual configuration. The integration syncs automatically.

Step 2: Create a Checkout Link

Go to your Checkout Links dashboard and create a new link. Add the products, variants, and quantities you want in the cart. Set a discount if you're running a promotion. Choose between percentage off, fixed amount, or free shipping.

Give the link a descriptive name like "Win-Back — 20% Off Best Sellers" so you can find it later.

Step 3: Copy the Link URL

Every checkout link has a short URL. Copy it. This is the URL you'll paste into your Klaviyo email.

Step 4: Add the Link to Your Klaviyo Email

In Klaviyo, open the flow or campaign email you want to edit. Select the CTA button (or add one). Paste your checkout link URL as the button destination.

That's it. When a customer clicks that button, they land on a Shopify checkout page with products and discounts already loaded.

Step 5: Test It

Send yourself a test email from Klaviyo. Click the checkout link. Verify the cart shows the correct products, quantities, and discount. Complete a test order if you want to confirm the full flow.

Pricing: Checkout Links vs Alternatives

Checkout Links is $25/month flat. No percentage fees, no revenue share, no per-link limits. Every feature included.

The real comparison isn't other apps — it's the manual alternative. Without checkout links, you create discount codes, paste them into emails, hope customers remember to enter them, and lose 30-40% of your conversions at the code entry step. Checkout Links eliminates that step entirely.

What Merchants Actually See

The numbers vary by store, but the pattern is consistent:

Higher email conversion rates. When you remove the steps between "click email" and "complete purchase," more people complete the purchase. Merchants using checkout links in Klaviyo flows typically see 2-3x higher conversion rates compared to standard product page links.

Fewer abandoned carts from email traffic. The irony of abandoned cart emails is that they often create new abandoned carts. Customer clicks the email, adds to cart, gets distracted, leaves. A checkout link skips the "add to cart" step entirely — the cart is pre-filled on arrival.

Cleaner attribution. Every checkout link has its own analytics. You can see exactly how many clicks, checkouts, and sales each link generated. Compare that to UTM parameters that break when customers copy-paste URLs or switch devices.

Higher average order value. Pre-loaded carts with complementary products convert better than "you might also like" recommendations. When the bundle is already in the cart with a discount applied, customers buy the bundle.

Get Started

Checkout Links integrates natively with Klaviyo. Connect your account, create a link, paste it into an email. The whole setup takes 10 minutes and the impact shows up in your next Klaviyo flow report.

If you're already sending Klaviyo emails to your Shopify customers — and you should be — checkout links turn those emails from "go browse our store" into "buy this right now." That's not a small difference. That's the difference between email marketing that costs money and email marketing that makes money.
