The 4 Klaviyo Flows That Drive 80% of Email Revenue (Setup + Benchmarks) (With Examples)
If you only build four Klaviyo flows for your Shopify store, build these four. Across our client base and the data we see at scale, these are the flows responsible for roughly 80% of all email-attributed revenue.
This post is the full breakdown — what each flow is, the timing structure that works, what to put in each email, the benchmarks to hit, and where most brands get this wrong. For broader context on email's role in Shopify growth, see how to grow Shopify sales with all-in-one marketing.

Key Takeaways
| Point | Details |
|---|---|
| The Pareto | Welcome + abandoned cart + browse abandonment + post-purchase ≈ 80% of email revenue. |
| Welcome series | 5–6 emails, first email within 5 min, conversion rate target: 8–12%. |
| Abandoned cart | 7 emails over 7 days, recovery rate target: 10–15% of carts. |
| Browse abandonment | 3 emails, lighter incentive, recovers warm intent that never made it to cart. |
| Post-purchase | 4 emails, drives second-order rate, the most underbuilt flow at most Shopify brands. |
Why These Four Flows
Klaviyo's own benchmark reports consistently show that the highest-revenue flows for ecommerce brands are the same ones year after year: welcome, abandoned cart, browse abandonment, and post-purchase. These four cover the buyer's full journey:
- Welcome — they just opted in. Highest intent of their life.
- Abandoned cart — they almost bought. Recovery is pure profit.
- Browse abandonment — they showed interest but didn't add to cart. Warm intent, untapped.
- Post-purchase — they bought once. Getting them to buy again is 5–10x cheaper than acquiring them new.
Campaigns matter too — but flows are evergreen revenue. Built once, they earn forever. Most brands have flows live but underbuilt; that's where the easy revenue is.
Flow 1: Welcome Series
The welcome series fires when someone subscribes (popup signup, footer signup, lead magnet, etc.). It's the highest-converting flow you'll ever own.
Structure: 5 emails over 7 days
| # | Send | Subject Pattern | Job |
|---|---|---|---|
| 1 | 5 min after opt-in | "Your code's inside →" | Deliver the welcome offer |
| 2 | +24 hr | "Why we exist" | Brand story, founder voice |
| 3 | +48 hr | "Our top sellers" | Product social proof |
| 4 | +96 hr | "Real customers, real reviews" | Trust signal |
| 5 | +6 days | "Your code expires tonight" | Urgency / last call |
What goes in each email
Email 1 (the conversion driver): Single CTA. The promo code or offer. Big, clean, no distractions. This email alone often drives 60% of welcome flow revenue.
Email 2 (founder voice): Why the brand exists. Don't sell here — build connection. Plain-text or lightly designed.
Email 3 (product proof): Top 3–5 sellers with one-line "why people love it" descriptions. Direct CTA back to the site.
Email 4 (social proof): 3 customer reviews + a UGC photo if you have one. The job is reducing risk before they spend.
Email 5 (urgency): The offer expires. Single CTA. Often the second-highest converting email in the flow after email 1.
Benchmarks
- Open rate: 50–65% (welcome flow gets the highest opens of any flow)
- Click rate: 8–14%
- Conversion rate (email → purchase): 8–12%
- Revenue per recipient (RPR): $1.50–$4.00 depending on AOV
What most brands get wrong
A single email saying "thanks for subscribing, here's 10% off." That's leaving 70% of welcome-series revenue on the table. The 5-email structure exists because most subscribers don't convert on email 1 — they convert on email 3, 4, or 5 once trust builds.
Flow 2: Abandoned Cart
The abandoned cart flow is your single most profitable automation. According to Baymard Institute's checkout abandonment research, the average ecommerce cart abandonment rate is around 70%. Recovering even 10% of those is enormous revenue.
We covered the full 7-email structure in the Shopify abandoned cart 7-email flow, but here's the short version:
Structure: 7 emails over 7 days
| # | Send | Job |
|---|---|---|
| 1 | +1 hour | Friendly reminder |
| 2 | +12 hours | Address concerns / offer help |
| 3 | +24 hours | Social proof / reviews |
| 4 | +48 hours | Soft incentive (free shipping) |
| 5 | +72 hours | Stronger incentive (10–15% off) |
| 6 | +5 days | FOMO / scarcity ("only X left") |
| 7 | +7 days | Final call / strongest incentive |
Benchmarks
- Open rate: 45–55%
- Click rate: 8–12%
- Cart recovery rate: 10–15% of abandoned carts
- Revenue per cart: 2–4x the cart value times recovery rate
What most brands get wrong
Stopping at 3 emails. The 4th–7th emails are where 40% of total flow revenue comes from. People don't buy on first reminder; they buy when life calms down or the incentive overcomes hesitation. See the full 7-email breakdown.
Flow 3: Browse Abandonment
Browse abandonment fires when someone views a product but doesn't add to cart. It's the most underbuilt of the four flows because it requires more setup — you need Klaviyo's web tracking installed and the "viewed product" trigger configured.
Structure: 3 emails over 5 days
| # | Send | Job |
|---|---|---|
| 1 | +4 hours | "Still thinking about [Product]?" — gentle nudge with product details |
| 2 | +48 hours | Social proof — reviews of the viewed product |
| 3 | +5 days | Soft offer + urgency on the specific product |
Benchmarks
- Open rate: 35–45%
- Click rate: 5–9%
- Conversion rate: 2–4%
- Revenue per recipient: $0.50–$1.50
Why it's worth building
Browse intent without cart-add is warm but quiet. These customers showed enough interest to view a product page but had a friction point before checkout — pricing, shipping, doubt. A 3-email gentle sequence often recovers 2–4% of these visits as orders, which compounds across thousands of monthly sessions.
Flow 4: Post-Purchase
The post-purchase flow is where most Shopify brands leave the most money on the table. The customer just bought. They like you. They're warm. And most brands send them a generic "thank you" email and then nothing for 30 days.
Structure: 4 emails over 30 days
| # | Send | Job |
|---|---|---|
| 1 | +1 hour | Warm thank-you, set delivery expectations |
| 2 | +5 days (after delivery) | Educational content — how to use / care for product |
| 3 | +14 days | Review request + UGC ask |
| 4 | +25 days | Cross-sell / second purchase incentive |
What goes in each email
Email 1: Genuinely warm tone. Confirm what they bought, when it'll arrive, who to contact for help. Plant a seed for the relationship.
Email 2: Practical value. How to use the product, care instructions, styling tips, recipes — whatever fits. The job is making them feel smart for buying.
Email 3: Review request. Add a UGC ask ("share a photo and tag us"). This is also where you build social proof for future customers.
Email 4: The second-purchase nudge. "Customers who bought X often add Y" or "your refill cycle is around now." This is where second-order rate gets unlocked.
Benchmarks
- Open rate: 50–65%
- Click rate: 6–10%
- Second-order rate uplift: 15–30% improvement vs. no flow
- Revenue per recipient: $2–$5 over 30 days
Why this is the highest-leverage flow to build
Acquiring a new customer costs 5–10x more than getting an existing one to buy again (HBR's classic customer retention research). The post-purchase flow is your highest-leverage retention asset. Brands with strong post-purchase flows commonly hit 40%+ repeat purchase rates; brands without them hover at 15–20%.
Sequencing: What Triggers What
The four flows interact. If a subscriber adds to cart while still in the welcome series, the abandoned cart flow needs to take priority. Klaviyo handles this with flow filters, but you need to set them up explicitly:
- Welcome series: filter out anyone who has placed an order
- Abandoned cart: filter out anyone who has placed an order in the last 24 hours
- Browse abandonment: filter out anyone with an active abandoned cart
- Post-purchase: trigger only on first or repeat order, depending on which version
Klaviyo's smart sending feature prevents the same person from getting hammered by multiple flows in a 16-hour window. Turn it on for every flow.
Common Mistakes
Single-email flows. "Thanks for subscribing, here's your code" is not a welcome flow. It's an autoresponder. Build the full 5–7 emails.
No filters between flows. A subscriber who buys in the welcome series shouldn't keep getting "use your welcome offer" emails. Set the filter.
Same incentive in every email. Repeating "10% off" across all emails of a cart flow trains people to wait for the discount. Vary the angle: reminder, social proof, free shipping, soft discount, urgency.
No segmentation. A first-time browser doesn't need the same email a 4x repeat customer gets. Build segment branches inside flows for engaged vs. cold subscribers.
Set and forget. Flows decay. Test new subject lines monthly, refresh creative quarterly, audit performance weekly. We covered this cadence in the Shopify operator stack 2026 edition.
Benchmarks to Hit
Across our client base, here's what "good" looks like for each flow at a Shopify brand doing $20k–$200k/mo:
| Flow | Open Rate | Click Rate | Revenue per Recipient |
|---|---|---|---|
| Welcome | 50–65% | 8–14% | $1.50–$4.00 |
| Abandoned cart | 45–55% | 8–12% | $4–$10 |
| Browse abandonment | 35–45% | 5–9% | $0.50–$1.50 |
| Post-purchase | 50–65% | 6–10% | $2–$5 |
Total email revenue contribution: these four flows alone should drive 25–40% of total Shopify revenue. If you're significantly under that, the issue is either flow quality or list size — not the channel.

Frequently Asked Questions
How many abandoned cart emails should I send?
Three is the standard that works: roughly 1 hour, 24 hours, and 72 hours after abandonment — reminder first, objection-handling second, incentive (if your margin allows) last. Brands with strong volume can extend to a longer sequence; we've broken down the economics of that in the 7-email abandoned cart flow.
I run a small ecommerce brand — how do I build email flows for abandoned cart, welcome, and post-purchase?
Build them in this order: abandoned cart first (highest revenue per hour of setup), welcome second (highest volume), post-purchase third (retention). Each needs only 2–3 emails to start — trigger timing matters more than copy polish on day one. The four flow breakdowns below include triggers, timing, and benchmarks for each.
Why are there only 4 flows on this list?
Because the data says these four drive ~80% of email revenue. Other flows (winback, VIP, replenishment, sunset) matter — but they're rounding error compared to the core four. Build these first, optimize them, then expand.
How long does it take to build all four flows?
A focused team can build and launch the full stack in 10–14 days. A traditional agency typically takes 4–6 weeks. We covered the build velocity question in why we ship in 14 days instead of 90.
Do I need a discount code in every email?
No — and you shouldn't. Discount in every email trains customers to wait. Use discount strategically (welcome email 1, welcome email 5, cart email 5 + 7) and build other emails on social proof, education, urgency, or pure brand voice.
What if my open rates are below the benchmarks?
Most likely a deliverability issue, not a creative one. Check your sender reputation in Google Postmaster Tools, authenticate your domain (SPF/DKIM/DMARC), and clean your list of unengaged subscribers every 90 days. We covered list health in common mistakes new Shopify store owners make.
Should I use AI to write these emails?
Yes — but with brand calibration. AI generates the variants, a human reviews tone and edits before send. We covered this in what an AI marketing agency actually does.
