If you are running an ecommerce store and still sending every email by hand, you are working harder than you need to and leaving serious money behind. Automated Klaviyo flows generate up to 30x more revenue per recipient than one-off campaigns, pulling in an average of £3.65 per recipient compared to just £0.11 from manual sends. That is not a rounding error. That is the difference between email being a side channel and email being your most profitable acquisition tool.

‍

At VXTX, a Brighton-based performance marketing agency, we set up Klaviyo for every ecommerce client before we touch a single ad account. Why? Because properly configured flows generate 30-40% of total email revenue on autopilot. The five automations in this guide are the exact flows we build first for every brand we work with. They are simple enough for a complete beginner to follow and powerful enough to add five figures in monthly revenue within 60 days.

Why Automated Flows Beat Manual Campaigns Every Time

‍

Before we get into the five flows, it is worth understanding why automations outperform campaigns so dramatically. A manual campaign goes out to your entire list at once, regardless of where each subscriber is in their buying journey. An automated flow triggers at exactly the right moment based on what a customer just did: signed up, abandoned a cart, made a purchase or stopped engaging.

‍

That behavioural trigger is what drives the numbers. Flows generate up to 30x more revenue per recipient because they reach people when intent is highest. A campaign email hits an inbox alongside dozens of others. A flow email arrives seconds after someone showed genuine interest in your product. The timing alone is worth the setup.

‍

The average ecommerce store we onboard at VXTX sees £20,000 to £48,000 in additional monthly revenue after implementing a complete Klaviyo automation stack. That figure is not aspirational. It is what happens when you stop treating email as a broadcast tool and start treating it as a revenue engine.

‍

Flow 1: The Welcome Series (3-5 Emails)

‍

Your welcome series is the single most important flow you will ever build. It is the first conversation you have with a new subscriber, and it sets the tone for the entire relationship. Get it right and you are looking at 45-50% open rates and 8-12% conversion rates, numbers that no campaign will ever touch.

‍

Trigger and Timing

‍

The flow triggers the moment someone joins your email list, whether that is through a pop-up, a footer form or a landing page opt-in. In Klaviyo, you set the trigger to "Subscribed to List" and select your main newsletter list.

‍

Here is the timing we use at VXTX for every client:

‍

Email 1 (Immediately): Welcome and deliver the incentive. If you promised 10% off, hand it over straight away. Include your brand story in two to three sentences and a clear call to action pointing to your bestsellers.

‍

Email 2 (Day 2): Social proof and trust building. Feature customer reviews, press mentions or user-generated content. Show new subscribers that real people buy from you and love the product.

‍

Email 3 (Day 4): Education and value. Teach the subscriber something useful about your product category. A skincare brand might share a routine guide. A coffee brand might explain brewing methods. Position yourself as the expert.

‍

Email 4 (Day 6): Urgency on the discount. If the welcome offer has not been redeemed, remind them it is expiring. Add a countdown or a specific deadline.

‍

Email 5 (Day 8): Final push with a bestseller spotlight. Highlight your top three products, include social proof for each and make the discount code prominent one last time.

‍

Add a conditional split after Email 1 so anyone who purchases is removed from the rest of the series and moved into your post-purchase flow instead. This stops you from offering a discount to someone who has already converted.

‍

Flow 2: Abandoned Cart Recovery (3 Emails)

‍

The abandoned cart flow is where email automation pays for itself fastest. If you only set up one flow, make it this one. Abandoned cart emails see 35-40% open rates and 15-20% conversion rates, with an average revenue per recipient of £3.65. But the real story is in the sequence length.

‍

A 3-email abandoned cart sequence generates 6.5x more revenue than a single email. The data backs this up clearly: brands running three-email sequences pulled in £24.9 million compared to £3.8 million from single-email setups. Sending one reminder and calling it done is leaving the vast majority of recoverable revenue on the table.

‍

The 3-Email Sequence We Build

‍

Email 1 (1 hour after abandonment): A simple, clean reminder. Show the exact products left in the cart with images and prices. No discount yet. The subject line should be direct: "You left something behind" or "Still thinking it over?" Keep the copy short and the CTA obvious.

‍

Email 2 (24 hours after abandonment): Social proof and objection handling. Include customer reviews for the abandoned products. Address common objections like shipping costs, returns policy or product quality. Still no discount in most cases, though this depends on your margin.

‍

Email 3 (48 hours after abandonment): Final reminder with urgency. This is where you can introduce a small incentive if your margins allow it: free shipping, 5-10% off or a bundled offer. Make it clear this is the last reminder. The scarcity is real because you will not be emailing them about this cart again.

‍

In Klaviyo, set the trigger to "Started Checkout" and add a filter that excludes anyone who has completed a purchase since the event fired. This prevents the embarrassing mistake of chasing someone who already bought.

‍

Flow 3: Browse Abandonment (2 Emails)

‍

Browse abandonment catches the shoppers who looked at products but never added anything to their cart. It is a wider net than abandoned cart, which means higher volume but lower intent. Expect 30-35% open rates and 3-5% conversion rates, which is still strong for what is essentially a "we noticed you looking" message.

‍

How Browse Abandonment Differs From Abandoned Cart

‍

The key difference is intent level. Someone who added to cart was one click from buying. Someone who browsed a product page might have been casually scrolling. Your messaging needs to reflect that. Browse abandonment emails should feel helpful and suggestive rather than urgent and recovery-focused.

‍

Email 1 (2 hours after browsing): "We thought you might like this." Show the product they viewed alongside two or three similar items. This is a recommendation email, not a recovery email. Keep the tone light and the layout visual.

‍

Email 2 (24 hours after browsing): Category-level recommendations. If they looked at running shoes, show your top-selling running shoes. Add a customer review or two and a soft CTA. No discount needed at this stage.

‍

Set the trigger to "Viewed Product" in Klaviyo with a filter that excludes anyone who started checkout or placed an order within the same window. You do not want browse abandonment emails going to people who are already in your cart flow. Also add a frequency cap so the same person does not receive this flow more than once every seven to fourteen days.

‍

Flow 4: Post-Purchase Thank You (2-3 Emails)

‍

Most brands focus all their energy on acquiring new customers and forget about the people who already handed over their money. The post-purchase flow fixes that. It builds loyalty, drives reviews and sets up the next sale. Post-purchase emails hit 40-45% open rates with a 10-15% repeat purchase rate.

‍

As the best performance marketing agency for ecommerce retention, we see post-purchase flows as the foundation of customer lifetime value. A first-time buyer who gets the right follow-up sequence is significantly more likely to buy again within 90 days.

‍

Email 1 (Immediately after purchase): Order confirmation and thank you. This is not your transactional receipt from Shopify. This is a branded email that reinforces the buying decision. Include order details, expected delivery time and a genuine thank you. Share a tip about the product if relevant.

‍

Email 2 (5-7 days after purchase / after delivery): Review request. Time this to land a day or two after the product arrives. Ask for a review and make it easy with a direct link. If you use a platform like Okendo, Yotpo or Judge.me, Klaviyo integrates directly so you can trigger based on delivery events.

‍

Email 3 (14 days after purchase): Cross-sell or replenishment. Recommend complementary products based on what they bought. A customer who purchased a face moisturiser might need a serum. Someone who bought coffee beans will need more in three to four weeks. If you sell consumables, this email can run on a replenishment cycle instead.

‍

The trigger in Klaviyo is "Placed Order." Add a conditional split based on first-time buyer vs. repeat buyer so you can adjust the messaging. A returning customer does not need the same brand introduction that a new buyer does.

‍

Flow 5: Sunset and Winback (2-3 Emails)

‍

Every list has subscribers who go quiet. The sunset and winback flow gives them one last reason to re-engage before you clean them off your list. This matters for deliverability as much as revenue. Sending to a list full of inactive contacts tanks your sender reputation, which hurts open rates across every flow and campaign you run.

‍

When to Trigger the Winback

‍

The general rule is 1.5x your average purchase cycle. If your average customer buys every 60 days, trigger the winback at 90 days of inactivity. If it is every 30 days, trigger at 45. Klaviyo makes this easy with engagement-based segments that track last open, last click and last purchase date.

‍

Email 1 (At trigger point): "We miss you" with a direct incentive. Offer something meaningful: 15-20% off, free shipping or an exclusive bundle. The subject line should create curiosity or nostalgia. Include a clear CTA and remind them what they are missing.

‍

Email 2 (5 days later): Last chance. Reiterate the offer and add urgency with a genuine deadline. Show what is new since they last engaged: new products, new reviews, anything that gives them a reason to come back.

‍

Email 3 (10 days later): The breakup email. Let them know you are about to stop emailing them. Give them one final link to stay subscribed. If they do not click, suppress them from your active list. This is list hygiene, and it is just as important as any revenue email you send.

‍

Cleaning your list regularly keeps your deliverability strong, which means every other flow performs better. Think of it as maintenance that protects the revenue from your other four automations.

‍

Getting the Technical Setup Right

‍

All five flows are built inside Klaviyo's flow builder using a drag-and-drop interface. You do not need a developer. But there are a few technical points that trip beginners up:

‍

Flow filters vs. trigger filters: Trigger filters determine who enters the flow. Flow filters check conditions before each email sends. Use both. For example, your abandoned cart flow should have a trigger filter for "Started Checkout" and a flow filter before each email that checks "Has not placed order since starting this flow."

‍

Smart sending: Klaviyo's smart sending feature prevents a subscriber from receiving multiple flow emails within a set window (default is 16 hours). Leave this on for most flows. Turn it off for time-sensitive ones like abandoned cart if you want tighter timing.

‍

UTM tracking: Tag every flow email with proper UTM parameters so you can track performance in Google Analytics. Klaviyo auto-adds UTMs, but customise them so you can distinguish between flows. Use utm_source=klaviyo, utm_medium=email and utm_campaign=flow-name for clean attribution.

‍

What to Expect After Setup

‍

Once all five flows are live and your store is generating consistent traffic, here is what we typically see across our client base at VXTX:

‍

Welcome series captures and converts new subscribers at scale. Abandoned cart recovers 15-20% of lost checkouts. Browse abandonment picks up the casual browsers. Post-purchase builds loyalty and drives repeat orders. Sunset keeps your list healthy so every other email performs at its peak.

‍

Combined, these five flows typically account for 30-40% of a brand's total email revenue. For a store doing £100,000 a month, that is an extra £30,000 to £40,000 running on autopilot with no ongoing campaign work required.

‍

The key is getting them set up properly from the start. Poor timing, weak copy or missing filters will undercut the results. If you are not confident in your setup, working with a performance marketing agency that specialises in Klaviyo and ecommerce retention will save you months of trial and error.

‍

The Bottom Line

‍

You do not need dozens of flows to start seeing results from Klaviyo. These five automations cover the full customer lifecycle from first visit to lapsed buyer, and they are responsible for the bulk of automated email revenue across every ecommerce brand we work with.

‍

Set them up in order: welcome series first, then abandoned cart, browse abandonment, post-purchase and finally sunset. Each one builds on the last, and together they create a system that turns traffic into revenue around the clock without you touching a thing.
