Why Klaviyo Post-Purchase Flows Are a Game-Changer – and How to Set Them Up Properly

When someone buys from your online shop, it’s easy to think the job’s done. The sale’s in, they’ve got what they came for, and you’re off the hook – right? Not quite. That moment after someone makes a purchase is actually one of the best opportunities to build loyalty, drive repeat orders, and turn a customer into a raving fan. That’s where Klaviyo’s post-purchase flows come in.

Whether you’re running a small Shopify store or a fast-growing ecommerce brand, getting your post-purchase emails sorted is a no-brainer. They're automated, easy to personalise, and once they’re set up right, they just tick along quietly in the background – doing a lot of the heavy lifting for you.

Let’s take a proper look at why Klaviyo’s post-purchase flows are worth your time, how to set them up, and what different ways you can use them to your advantage.

Why Post-Purchase Flows Matter

Think of a post-purchase flow like a well-timed follow-up after a good night out. You wouldn’t ghost your mate after a great evening, and you shouldn’t ghost your customer after they’ve trusted you with their money. It's about respect – and about keeping that relationship going.

Post-purchase flows:

• Improve customer experience – Customers like to be kept in the loop. A well-written order confirmation, shipping update or thank-you email goes a long way.

• Reduce buyer’s remorse – A reassuring email straight after a purchase helps calm any post-checkout nerves. Show the customer they made a smart decision.

• Encourage repeat purchases – Once someone’s bought from you, they’re way more likely to do it again – if you stay in touch and give them a reason.

• Gather useful feedback – Ask for a review, a rating, or a quick reply. It's pure gold for improving your products and proving social proof to new buyers.

• Upsell and cross-sell – Done right, you can gently suggest complementary items without being pushy or annoying.

And the best part? It’s all automated. You set it up once, and it keeps working 24/7.

How to Set Up a Klaviyo Post-Purchase Flow

Right, let’s get practical. Setting up a post-purchase flow in Klaviyo is straightforward, but it works best when you actually think about why you’re sending each email, not just what it says.

1. Start With the Trigger

In Klaviyo, your flow starts with a trigger. For post-purchase, that’s usually something like:

• “Placed Order” – the moment someone completes checkout.

• “Fulfilled Order” – when the order is packed and sent.

• “Delivered Order” – if you’ve got delivery tracking integrated.

Pick the one that suits the moment you want to reach out.

2. Map Out the Journey

Instead of just one email, think in terms of a sequence. A good post-purchase flow might include:

• Order confirmation email – Immediate, reassuring, includes order details.

• Shipping confirmation – Update with tracking link.

• Thank-you email – Warm, friendly, and maybe even a wee personal message.

• Product usage tips – If it’s something that needs explaining, give them a hand.

• Review request – Wait until they’ve had time to use it, then ask for feedback.

• Upsell/cross-sell email – Suggest another product that complements what they bought.

• Loyalty or referral programme – Introduce any rewards or discounts for sharing.

You don’t have to use all of these, but even 1 or 2 can make a huge difference.

3. Segment Your Audience

Not all customers are the same, so don’t send them the same emails. You can set up conditional splits based on:

• What they bought

• First-time buyer vs repeat

• Order value

• Location

• Subscription status

For example, if someone bought skincare, you might send usage tips. But if they bought a candle, maybe you share care instructions or suggest a matching scent.

4. Add Personal Touches

Use dynamic content blocks in Klaviyo to personalise emails with their name, order details, or even a recommended product based on their last purchase.

If you’re from a smaller brand or more boutique setup, don’t be afraid to sound human too. Add a sign-off with your name like “Mike from Your Brand” – it helps people connect with your business.

Ways You Can Use Post-Purchase Flows Creatively

It’s not just about confirmations and receipts. Here are a few more creative ways to use post-purchase flows:

• “How did we do?” surveys – Gather insights while the experience is still fresh.

• Content emails – Link to blog posts, how-to guides, or community stories.

• Anniversary emails – “One year since your first order!” – simple, effective.

• Birthday clubs – Collect dates and send a little something each year.

• Returns guidance – Ease post-purchase anxiety by clearly explaining returns.

The key is to help and delight the customer, not just sell to them.

Final Thoughts

If you’re serious about growing your digital presence, don’t overlook your post-purchase flows. They’re not just about sending emails – they’re about keeping promises, building trust, and creating moments that bring people back.
