Shopify Platinum Partner · Klaviyo tech partner · Last reviewed August 2026
Klaviyo's own 2026 benchmark data, drawn from more than 183,000 brands, shows automated flows generate roughly 41% of email revenue from just 5.3% of sends, with revenue per recipient about 18 times higher than one-off campaigns. Most Shopify brands have this backwards: they send campaigns and underbuild flows. The fix is a build order, not more sending.
| Flows share of revenue | Share of sends | Flow RPR vs campaign | Flows most brands have | Top performers |
|---|---|---|---|---|
| ~41% | 5.3% | ~18x | 4 to 6 | 12 to 16 |
What Klaviyo does that Shopify Email does not
Klaviyo adds revenue attribution, purchase-behaviour segmentation and predictive analytics that Shopify Email does not have. It ties each order back to the specific email or flow that earned it, segments on what customers browsed and bought rather than what they opened, and predicts lifetime value, churn risk and next order date. Shopify Email handles campaigns and basic automations. Klaviyo handles multi-step flows and SMS.
Revenue attribution is the actual dividing line, and most comparisons skip it. Without it you see opens and clicks, then guess at which emails made money. Klaviyo's Shopify integration passes event-level order data, so a flow's revenue per recipient is measurable and you decide what to build next from evidence. Every other difference between the two tools follows from that one.
To be accurate about Shopify Email, since a lot of coverage is not: it does include marketing automations, among them abandoned checkout and welcome sequences. It is not purely a broadcast tool. What it lacks is per-email revenue attribution, conditional multi-step logic, and prediction.
| Shopify Email | Klaviyo | |
|---|---|---|
| Campaigns | Yes | Yes |
| Basic automations | Yes | Yes |
| Multi-step conditional flows | No | Yes |
| Revenue attribution per email | No | Yes |
| Purchase-behaviour segmentation | Limited | Yes |
| Predicted CLV, churn risk, next order date | No | Yes |
| SMS | Separate | Built in |
| Cost | Free allowance, then per email | Free to 250 profiles, then subscription |
When to switch. Klaviyo starts paying for itself once email-attributed revenue clears roughly $0.50 per subscriber per month. Below that you are paying for capability you are not using, and Shopify Email or Klaviyo's free tier up to 250 profiles is the more sensible answer. Most sources put the crossover for Shopify brands above roughly $30,000 to $50,000 in monthly revenue.
Which Klaviyo flows should I build first?
Build five flows in this order: abandoned cart, welcome series, post-purchase, browse abandonment, then winback. Those five cover roughly 80% of Klaviyo-attributed revenue for a typical Shopify store. The order matters because abandoned cart carries the highest revenue per recipient of any flow, so it compounds fastest while the others are still being built.
- Abandoned cart. Highest revenue per recipient of any flow, reported around $3.65 on average, and a three-email sequence rather than one reportedly multiplies it several times over. Build this first, always. If you build nothing else, build this.
- Welcome series. Highest engagement rates in the whole account. Klaviyo's benchmark data puts welcome flow open rates at 40% to 60% against 18% to 25% for campaigns. This is also where you set expectations about send frequency, which pays off in deliverability later.
- Post-purchase. The cheapest repeat purchase you will ever buy. Someone who just bought is the most likely person to buy again, and most brands say nothing to them until the next campaign.
- Browse abandonment. Lower revenue per recipient than cart abandonment, roughly $0.50 to $1.50, but a much larger audience, so the absolute revenue is meaningful. Worth building once you are above roughly 5,000 monthly product page visitors.
- Winback. Triggered at 90 to 180 days without a purchase. Two emails: one without a discount, one with. Recovers customers who would otherwise churn silently.
Everything after these five is refinement. Build them in this order, get each one earning, then extend.
The gap nobody measures: How many Klaviyo flows should I have?
Top-performing brands run flows for 12 to 16 distinct customer actions. Most brands cover 4 to 6. Every uncovered action is a moment where a customer did something meaningful and heard nothing back, which is leaked revenue rather than a missed optimisation.
Work through your own list and mark which have a flow. Cart abandoned. Checkout started but not completed. Product viewed repeatedly. Back in stock. Price dropped. First order placed. Second order placed. Review requested. Subscription renewal upcoming. Subscription paused. Loyalty threshold reached. Birthday. Ninety days silent. Six months silent.
Counting the gaps is a five-minute exercise and it usually explains the revenue shortfall better than any campaign audit.
Why do Klaviyo flows outperform campaigns?
Relevance and timing beat frequency. Klaviyo's 2026 data shows flows deliver a 5.58% click rate against 1.69% for campaigns, roughly 13 times the placed order rate, and about 18 times the revenue per recipient. Nearly 48% of flow revenue comes from first-time buyers, against about 16% for campaigns.
| Flows | Campaigns | |
|---|---|---|
| Share of send volume | 5.3% | 94.7% |
| Share of email revenue | ~41% | ~59% |
| Click rate | 5.58% | 1.69% |
| Placed order rate | ~13x higher | baseline |
| Revenue from new buyers | ~48% | ~16% |
That last row is the one worth sitting with. Flows are not only a retention tool. They convert first purchases too, which is why welcome, browse and abandonment sequences matter more than most brands assume.
These are vendor-compiled figures and are not independently audited, so treat them as directional. The pattern holds across independent datasets, which is enough to act on.
How much does Klaviyo cost for a Shopify store?
Klaviyo is free up to 250 active profiles, then roughly $20 per month at 500 contacts, $150 at 10,000 and $2,315 at 200,000 on email-only plans, as reported in April 2026. SMS is a separate add-on with per-message fees. Since a February 2025 billing change, all active profiles count toward billing, including people who have unsubscribed.
That billing change is the part almost nobody flags. A profile that will never receive another email from you is still billable unless it is suppressed. Quarterly profile cleanup is therefore the largest cost-control lever in Klaviyo, and it improves deliverability at the same time, because you stop sending to addresses that never engage.
Reported tiers, April 2026: free to 250 profiles, then approximately $20 at 500, $45 at 1,000, $60 at 2,500, $100 at 5,000, $150 at 10,000, $400 at 25,000, $720 at 50,000, $1,380 at 100,000 and $2,315 at 200,000. Confirm current figures at klaviyo.com/pricing before forecasting, because these tiers move and every number here is third-party reported rather than published by Klaviyo directly.
What percentage of revenue should come from email?
Twenty to thirty percent of total ecommerce revenue from email and SMS combined is a reasonable target. If you are well below that with a healthy list, the usual cause is underbuilt flows rather than insufficient campaign volume, since flows produce roughly 41% of email revenue from 5.3% of sends.
| Metric | Target |
|---|---|
| Email and SMS share of total revenue | 20% to 30% |
| Campaign open rate | ~31%, top performers 45%+ |
| Welcome flow open rate | 40% to 60% |
| Flow click rate | ~5.5% |
| Inbox placement | 95%+ |
| Bounce rate | Below 0.5% |
| Spam complaint rate | Below 0.08% |
One caution on open rates. Apple's Mail Privacy Protection inflates them, so a 35% to 42% open rate may not mean what it appears to. Click rate, placed order rate and revenue per recipient are the metrics that survive contact with reality.
Why are my Klaviyo emails not reaching the inbox?
Usually authentication or list hygiene. Check SPF, DKIM and DMARC on a dedicated sending domain first, then check whether you are sending to profiles that have not engaged in a year. Klaviyo's inbox placement runs roughly 92% to 96% for properly authenticated senders, which means authentication is your responsibility rather than the platform's.
Deliverability breaks silently. Platform dashboards will not tell you until the problem is severe, so monitor placement with an external tool rather than trusting the in-platform view.
Warm a new sending domain gradually rather than sending to your whole list on day one. If you are migrating from another platform, run a two-week pilot on your own domain before switching everything across. Target 95% inbox placement, bounce below 0.5% and spam complaints below 0.08%.
What is a Klaviyo audit?
A Klaviyo audit reviews four things: which lifecycle actions have flows and which do not, whether existing flows are earning or merely running, list and deliverability health, and whether you are paying for profiles that should be suppressed. It produces a ranked list of what to fix, and the profile cleanup alone often covers the cost of the audit.
Ours runs as a 10-hour block at $1,500, with findings in five working days. Several of the fixes are configuration your own team can do, and those get handed over rather than billed.
When Klaviyo is the wrong choice
Below 250 subscribers, below roughly $0.50 of email-attributed revenue per subscriber per month, or where more than half your revenue is B2B. Klaviyo is built for consumer behaviour, so wholesale buyers do not respond to browse abandonment flows and account-level pricing belongs in your ERP rather than your email platform.
We are a Klaviyo technology partner, so weigh this accordingly.
- You are just starting. Use the free tier or Shopify Email, and come back when there is a list to work with.
- Email revenue is below the threshold. You are paying for capability you are not using.
- You are majority B2B. See Shopify B2B development for how wholesale pricing and buyer communication are usually handled instead.
- Nobody will own it. Klaviyo rewards ongoing attention. An account nobody touches decays: flows go stale, lists get dirty, deliverability slides. If there is no owner, a simpler tool is the honest answer.
Klaviyo work we have delivered
Klaviyo is one of our named technology partners, alongside Attentive, Sendlane, Stay.ai, ReCharge, Yotpo, Smile.io and Loyalty Lion. A Klaviyo specialist sits on every project team we staff, rather than retention being handed to a generalist after launch.
Food and beverage brands with subscription programmes typically see email and SMS at the upper end of the 20% to 30% range, because replenishment flows carry the load. Wild Planet's programme spans Smartrr subscriptions and Klaviyo retention.
What we build
- Flow architecture. The five core flows in build order, then extension toward the 12 to 16 actions top performers cover.
- Shopify integration and event data. The native Klaviyo app takes minutes to connect. Getting the event data clean, and making sure custom actions on your storefront actually fire, is the part that needs engineering. Where a storefront event does not exist yet, that becomes custom app work.
- Segmentation and predictive use. Predicted lifetime value and next order date applied to real send decisions rather than sitting unused in the dashboard.
- Deliverability setup. Dedicated domain, authentication, warm-up, and monitoring.
- Signup form performance. Popups and embedded forms are a common cause of layout shift, which affects Core Web Vitals and therefore conversion. We build them so they do not cost you the visitor they were meant to capture. See Shopify speed optimization.
- Customer data alignment. Klaviyo should receive customer records, not author them. Where a CRM or ERP holds the master record, that direction matters, and our Shopify ERP integration page covers which system should own what.
- Reporting. One dashboard covering email and SMS revenue as a share of total, flow versus campaign split, top flows by revenue, deliverability health, and repeat purchase rate by 30, 60 and 90 day cohorts.
Klaviyo during a replatform
If you are migrating to Shopify, retention setup belongs inside that project. Rebuilding flows after launch means a gap where abandoned carts go unrecovered, and that gap is expensive. Phase 5 of our free 100-point migration checklist covers where retention sits in the sequence, and Shopify Plus migration services covers the wider project.
What it costs
Klaviyo licensing is paid directly to Klaviyo. Our work on it runs at $150 per hour, with hour blocks from 10 hours at $1,500 and retainers from 20 hours or $3,000 per month. A flow build across the core five typically fits a first month of retainer. Full rates: Shopify Plus cost.
Retention work suits a retainer better than a project, because flows need iteration against real data rather than a single build and handoff.
Frequently asked questions
What does a Klaviyo agency actually do?
A Klaviyo agency builds and maintains your automated flows, sets up segmentation and deliverability, connects Klaviyo properly to your Shopify event data, and reports on what each flow earns. The build is the small part. Most of the value is in iterating flows against real revenue data over months, which is why this work suits a retainer rather than a one-off project.
How do I choose a Shopify email marketing agency?
Ask three questions. First, how many flows do they build as standard, and in what order? An agency that cannot name a build order does not have one. Second, what do they report on? If the answer is opens and clicks rather than revenue per recipient and flow-versus-campaign split, they are measuring the wrong things. Third, who owns deliverability? If nobody claims it, it will not get done.
Which agency handles Klaviyo migrations?
Any competent Klaviyo partner can move lists and rebuild flows. The part that separates them is sender reputation. Ask whether they run a pilot on your own domain before switching, how they warm a new sending domain, and how they handle the transition period when both platforms are live. An agency that treats a migration as a data export has not done many.
What is a Klaviyo audit?
A Klaviyo audit reviews four things: which lifecycle actions have flows and which do not, whether existing flows are earning or just running, list and deliverability health, and whether you are paying for profiles that should be suppressed. It produces a ranked list of what to fix, and the profile cleanup alone often pays for the audit.
How many Klaviyo flows should I have?
Five to start, in this order: abandoned cart, welcome, post-purchase, browse abandonment, winback. Those cover roughly 80% of Klaviyo-attributed revenue for a typical Shopify store. Top-performing brands eventually run flows for 12 to 16 customer actions, while most cover 4 to 6.
How much does Klaviyo cost for a Shopify store?
Free up to 250 active profiles, then roughly $20 per month at 500 contacts rising to about $720 at 50,000 and $2,315 at 200,000 on email-only plans. SMS is priced separately. Since February 2025 all active profiles count toward billing, including unsubscribed ones, so quarterly profile cleanup is the biggest cost lever available to you.
Is Klaviyo better than Shopify Email?
For any store where email is a real revenue channel, yes. The difference is revenue attribution, purchase-behaviour segmentation and predictive analytics, none of which Shopify Email offers. Below roughly $0.50 of email-attributed revenue per subscriber per month, Shopify Email or Klaviyo's free tier is the more sensible answer.
What percentage of revenue should come from email?
Twenty to thirty percent of total ecommerce revenue from email and SMS combined is a reasonable target. If you are well below that with a healthy list, the usual cause is underbuilt flows rather than insufficient campaign volume.
Why are my Klaviyo emails not reaching the inbox?
Usually authentication or list hygiene. Check SPF, DKIM and DMARC on a dedicated sending domain first. Then check whether you are sending to profiles that have not engaged in a year, which damages reputation for everyone else on your list. Target 95% inbox placement, bounce below 0.5% and spam complaints below 0.08%.
