Your Klaviyo flows are either generating 25 to 40 percent of your total revenue automatically, or you have a serious leak in your retention system. There is no in-between. This is the complete playbook for every flow a D2C brand should have running, what each should look like, and what performance numbers to expect from each.
Why Flows Beat Campaigns Every Time
Campaigns are one-to-many. You write them once, send them once, and move on. Flows are one-to-one, triggered by specific customer behaviour, and run 24 hours a day without any ongoing effort after setup.
The math: a single abandoned cart flow email typically generates $5 to $8 in revenue per recipient. A campaign email to your full list generates $0.10 to $0.30 per recipient. Flows win because they are sent at the moment of highest purchase intent. That timing is everything.
Top-performing D2C brands generate 30 to 40 percent of total email revenue from automated flows. If yours is generating under 20 percent, this guide will change that.
The Welcome Series: Your Highest-ROI Flow
The welcome series triggers the moment someone joins your list, typically from a pop-up offering 10 to 15 percent off. Open rates average 45 to 55 percent on email one, making it the most-read email you will ever send. Use it well.
A five-email welcome series structure that converts: Email 1 (immediate): deliver the discount, establish the brand story in one paragraph, and show the top three products. Email 2 (day 2): tell the founding story. Not the brand story, the founder story. Why did this specific person start this company? What problem were they solving for themselves? Email 3 (day 4): social proof heavy. Lead with a customer result, show reviews from real people on specific products, and feature UGC if you have it. Email 4 (day 7): urgency on the discount expiring, objection handling, and a FAQ section covering the top three reasons people do not buy. Email 5 (day 10): last chance, softer tone, offer an alternative product if the original is not right for them.
Benchmark performance: 45 to 55 percent open rate on email 1, 25 to 35 percent on emails 2 and 3, 15 to 25 percent on emails 4 and 5. Conversion rate from welcome series to first purchase: 12 to 20 percent of new subscribers. If you are below 10 percent, start with the offer and the subject line on email 1.
Abandoned Cart Flow: Recovering Your Biggest Revenue Leak
70 percent of people who add to cart do not complete checkout. Abandoned cart flows recover 5 to 15 percent of them. At scale, this single flow can add six figures annually to a $1M plus brand.
Three-email abandoned cart sequence: Email 1 at 1 to 4 hours after abandonment: no discount, just a simple reminder showing exactly what they left behind. Include the product image prominently, the price, and one line of social proof (star rating and review count). Email 2 at 24 hours: add a question. "Still deciding?" opens a loop. Address the most common objection for your category. For supplements, this is often safety or efficacy. For fashion, it is sizing. For premium goods, it is price. Tackle the real objection directly. Email 3 at 48 to 72 hours: offer a discount (5 to 10 percent or free shipping), create urgency if inventory allows it, and make the CTA unmistakably clear.
Benchmark performance: Email 1 should achieve 40 to 50 percent open rate and 5 to 10 percent click rate. Email 2 around 35 to 45 percent open rate. Email 3 around 25 to 35 percent open rate with a slight CVR boost from the offer. Total abandoned cart recovery rate: 5 to 15 percent of abandoners.
Post-Purchase Flow: Turning One-Time Buyers Into Lifetime Customers
The post-purchase flow starts after the first order and runs for 45 to 60 days. Its job is to educate, delight, and generate a second purchase. This is where LTV is built.
A six-email post-purchase structure: Email 1 (order confirmation, immediate): this is transactional and expected. Add one branded element, a personal note from the founder, and set expectations for delivery time. Email 2 (day 2 after delivery confirmation): product usage guide. How to get the most out of what they bought. For supplements: when to take, how to stack, what to expect in the first 30 days. For fashion: care instructions, styling ideas, how to size your next purchase. Email 3 (day 5): social proof plus community. Show customer results, invite them to follow your social accounts, share your brand hashtag. Email 4 (day 10): review request. Keep it simple. One tap star rating, then a text box. Offer 5 percent off their next order for leaving a review. Email 5 (day 21): cross-sell or upsell. Based on what they bought, recommend the logical next product. Do not recommend the same product they just bought. Recommend what customers who bought that product also love. Email 6 (day 45): replenishment prompt if your product has a predictable use cycle. For a 30-day supplement supply, send this at day 25, not day 45.
Benchmark: Post-purchase flows should drive a 25 to 35 percent second purchase rate within 60 days. Below 20 percent means either the product experience is poor or the email content is not addressing the right motivations.
Browse Abandonment: The Underused Flow Worth Serious Revenue
Browse abandonment triggers when someone views a product page but does not add to cart. The audience is 10 times larger than abandoned cart (far more people browse than add to cart), but converts at a lower rate (0.5 to 2 percent versus 5 to 15 percent for cart abandonment). The volume makes it worth building.
A two-email browse abandonment sequence: Email 1 at 2 to 4 hours: show the product they viewed with a hero image, the product name, and three key benefits. No discount yet. Email 2 at 24 hours: a soft offer (free shipping or a small discount) and two or three alternative products in case this specific item is not right.
Do not send browse abandonment emails to people who just purchased. Filter out purchasers from the trigger condition.
Win-Back Flow: Reactivating Lapsed Customers
Customers who purchased once and have not returned in 90 to 120 days need a win-back campaign. They already know and trust your brand. Reactivating them costs 60 to 80 percent less than acquiring a new customer.
A four-email win-back sequence: Email 1 (90 days after last purchase): no offer, just a check-in. "We noticed you have not visited recently." Show new products or bestsellers. Email 2 (7 days later): 10 percent off, framed as an exclusive offer for valued past customers. Email 3 (14 days later): 20 percent off, stronger urgency language. Final email 4 (21 days later): last chance offer, then suppress them from regular campaigns if they do not open or click this email. Sending to chronically disengaged subscribers destroys your sender reputation.
VIP Flow: Treating Your Best Customers Differently
VIP customers, defined as those in the top 10 percent by lifetime spend or with 3 plus orders, should receive different treatment. A VIP trigger fires when a customer crosses a spend threshold (for example, $300 lifetime spend) or completes a certain number of orders.
VIP flow content: recognition (explicitly thank them for their loyalty), an exclusive offer not available to the general list, early access to new products, and a personal touch such as a handwritten thank-you note with their next order. VIP customers typically have 3 to 5 times the LTV of average customers. Treating them as such compounds that advantage.
Klaviyo Flow Setup Mistakes to Avoid
Setting incorrect trigger filters is the most common and costly mistake. Your abandoned cart flow should not trigger for people who just purchased. Your win-back flow should not trigger for recent purchasers. Your welcome series should suppress once someone buys. Check every flow's filter conditions before activating.
Not suppressing unengaged subscribers from flows. Subscribers who have not opened an email in 180 plus days should be suppressed from most flows. They drag down your engagement metrics and hurt your sender reputation.
Making flows too long. Six emails in a post-purchase flow is a guideline, not a minimum. If your open rate drops below 15 percent by email 4, you have already lost most of your audience. Cut it there and make the remaining emails better, not more.
