TL;DR: Track five Klaviyo metrics weekly: revenue per recipient, campaign click rate, spam complaint rate, bounce rate, and flow revenue share. Review list growth, per-flow RPR, and email's share of Shopify revenue monthly. Benchmarks across 183,000+ brands: 31% campaign open rate, 1.69% click rate, 0.16% placed order rate. Treat open rate as directional only, build engaged segments on clicks and purchases, and verify Klaviyo's revenue numbers against Shopify every month.
Klaviyo metrics are the numbers that tell a Shopify operator whether email is making money: across 183,000+ brands, Klaviyo's 2026 benchmarks put the average campaign open rate at 31%, click rate at 1.69%, and placed order rate at 0.16%. Those three numbers are the starting line, not the finish.
Here's the problem. Klaviyo surfaces dozens of stats, and most don't deserve your attention. Some are inflated by Apple's privacy changes. Some measure activity instead of revenue. And a few, ignored for two weeks, can quietly wreck your sender reputation.
This guide covers the Klaviyo metrics that matter, what good looks like for each one, where to find them inside the platform, and (the part most guides skip) what to actually do when a number moves. You'll leave with a five-metric weekly check that takes 15 minutes and catches problems before they cost you a month of revenue.
Which Klaviyo metrics matter?
Nine Klaviyo metrics cover what an operator needs: open rate, click rate, placed order rate, revenue per recipient, attributed revenue, unsubscribe rate, spam complaint rate, bounce rate, and list growth. Five deserve a weekly look. The rest are monthly checks against benchmarks.
The raw data lives under Analytics > Metrics, where every event Klaviyo tracks (Opened Email, Clicked Email, Placed Order) has its own feed. For anything decision-ready, build a Custom Report under Analytics, which lets you pull revenue per recipient by campaign or flow over any date range.
Klaviyo also ships a built-in Benchmarks report that compares your account against roughly 100 companies similar to yours in size and vertical. Use it. A 28% open rate might be weak for a supplement brand and strong for a furniture store, and peer context beats a global average every time.
The rest of this guide goes metric by metric, then covers the part nobody writes about: which of these numbers lie to you, and how to read the ones that don't.
What is a good open rate?
A good Klaviyo campaign open rate is 31% or higher. That's the average across 183,000+ brands in Klaviyo's 2026 email marketing benchmarks, and the top 10% of brands clear 45.1%. Sit below 25% for a month and you're looking at a deliverability problem, not a creative problem.
Across the Shopify stores we manage at CartStrings, the average open rate is 39%, and email drives 32% of total store revenue. The gap between 31% and 39% rarely comes from better subject lines. It comes from cleaner lists, tighter sending segments, and a sender reputation that inboxes trust.
One warning before you celebrate a high open rate: a chunk of your opens aren't real. Apple's Mail Privacy Protection fires opens automatically whether the subscriber looked at your email or not. We'll cover exactly how to handle that in the vanity metrics section below. The short version: watch open rate for sudden drops, not for wins.
What is a good click rate?
A good campaign click rate is 1.69% or better, based on Klaviyo's benchmark data. Klaviyo calculates it as unique clicks divided by emails delivered, not sent. One subscriber clicking five links counts once, and bounced emails are removed from the denominator before the math happens.
That unique-versus-total distinction matters when you compare tools or agencies. Total clicks flatter the report. Unique clicks over delivered, which is Klaviyo's standard per its own help docs, tells you how many actual humans engaged.
Two related numbers sharpen the picture. Click-through-open rate (CTOR) is clicks divided by unique opens; it isolates whether your content converted the people who showed up, which makes it useful for judging design and offer strength. And placed order rate, the share of delivered recipients who bought, averages just 0.16% for campaigns. That sounds tiny until you multiply it across a 50,000-person list every week.
Click rate is the most honest engagement metric you have. It can't be faked by a privacy proxy, and it's the signal Klaviyo's smarter features key off. When we build engaged segments, clicks and purchases define them, never opens.
What is revenue per recipient?
Revenue per recipient (RPR) is attributed revenue divided by the number of people who received the message. It's the single best measure of email quality because it rolls deliverability, engagement, and conversion into one number. Klaviyo's abandoned cart benchmark report puts the average abandoned cart flow at $3.65 RPR, with the top 10% earning $28.89.
The same report puts welcome flows at $2.65 RPR on average, and $21.18 for the top 10%. Those spreads are the most useful numbers in this article. A brand at $3.65 per cart abandoner and a brand at $28.89 are sending to the same trigger. The difference is segmentation, timing, offer, and follow-up depth. The average abandoned cart flow converts 3.33% of recipients into buyers, so there's real money on the table.
Attributed revenue, the input to RPR, is every dollar Klaviyo credits to a specific email or SMS. It's the number your dashboard headline shows, and it comes with a catch we'll get to shortly: Klaviyo's attribution model is generous, and Shopify gets the final word.
Use RPR to rank everything. Campaigns, flows, even individual emails inside a flow. It's the metric that answers "was this message worth sending?"
Flow vs campaign benchmarks
Flows and campaigns are different animals, and judging them on the same scale will mislead you. Klaviyo's benchmark data shows flows average a 5.58% click rate and a 2.11% placed order rate, against 1.69% and 0.16% for campaigns. That's roughly 13x the conversion rate per delivered email.
The reason is intent. A campaign interrupts someone's inbox on your schedule. A flow answers a behavior the subscriber just performed: they signed up, abandoned a cart, or made a purchase. Timing plus relevance is the whole game.
Here's the number that should shape your roadmap: Klaviyo's data shows flows drive about 41% of email revenue from only 5.3% of total sends. Check your own split in a Custom Report. If your flows contribute far less than that 41% mark, your automations are underbuilt, and that's usually the fastest revenue fix available. Building out Klaviyo email automations that cover the full customer lifecycle is how you close that gap.
Track flow revenue share weekly. It's the ratio that tells you whether your email program earns while you sleep or only when you hit send.
List health and deliverability
These four metrics won't show up in a revenue report, but they decide whether your emails reach the inbox at all.
- Unsubscribe rate. Klaviyo's deliverability standard is 0.2% or below per send. Occasional spikes after aggressive campaigns are normal. A sustained climb means your frequency or targeting is off.
- Spam complaint rate. This is the one that can end your program. Google's email sender guidelines require keeping your Postmaster Tools spam rate below 0.10%, and never letting it hit 0.30%, per Google's sender guidelines. At that threshold, Gmail starts filtering you regardless of how good your content is.
- Bounce rate. Hard bounces are dead addresses; Klaviyo suppresses them automatically. Watch for spikes after a list import or a long gap in sending. A bounce spike is a list quality alarm, and it damages sender reputation fast.
- List growth. Measure it net: new subscribers minus unsubscribes and suppressions. A list that grows 2,000 and churns 1,900 isn't growing. If capture is the weak side, your popups and email capture setup is the lever to pull.
Klaviyo's Deliverability Hub grades all of this on a 0 to 100 score, from Poor (0 to 49) to Excellent (90 to 100). If yours sits below 70, fix that before touching anything else; dedicated deliverability work compounds every other metric on this page.
Vanity vs diagnostic metrics
Every Klaviyo metric is one of two things: a scoreboard you brag about, or a diagnostic that tells you what to fix. Operators get in trouble when they treat diagnostics as scoreboards. This section is the framework we use to read a Klaviyo account in minutes.
The diagnostic map
Metrics move together, and the pattern tells you where the problem lives.
- Open rate drops, everything else flat: that's a deliverability and domain reputation signal, not a creative problem. Don't rewrite subject lines. Check spam rate, bounce rate, and your Deliverability Hub score.
- Click rate drops while opens hold: the offer or content is the problem. People showed up and didn't care. Fix the hook, the product focus, or the send segment.
- RPR drops while clicks hold: the email did its job. Look downstream at segmentation, average order value, or the landing page you're sending traffic to.
One glance at which metric moved, and which stayed put, replaces a week of guessing.
Open rates after Apple MPP
Litmus data shows Apple email clients account for about 49.29% of all opens, and Apple's Mail Privacy Protection auto-fires open events whether the reader ever saw the email. Meanwhile Google states it doesn't track open rates at all. So roughly half your opens are machine-generated, and the world's biggest inbox provider ignores the metric entirely.
The operator's response has three parts. Define engaged segments on clicks and purchases, never opens. Treat open rate as directional only; compare it against your own history, not as an absolute truth. And keep it as a deliverability tripwire, because a sudden 10-point drop still reliably signals an inbox placement problem even when the absolute number is inflated.
The attribution sanity check
Klaviyo's conversion metrics use last-touch attribution inside a set window: if someone opened or clicked and then bought within that window, Klaviyo takes credit. That's per Klaviyo's own campaign analytics documentation, and it means Klaviyo-attributed revenue is not the same as Shopify truth. A customer who clicked your email Tuesday and bought through a Google ad Thursday can count in both columns.
So run a monthly sanity check: compare Klaviyo's attributed revenue against Shopify's sales-by-channel report. For context, email at 20 to 30% of total store revenue is typical, 30 to 40% is strong, and 40%+ is elite. If Klaviyo claims 55% and Shopify shows email driving 18%, your attribution window is writing checks your store isn't cashing.
Your weekly metric cadence
Weekly, in about 15 minutes: revenue per recipient on recent campaigns, campaign click rate, spam complaint rate, bounce rate, and flow revenue share. These five catch offer fatigue and deliverability damage while they're still cheap to fix.
Monthly, in under an hour: email's share of Shopify revenue (verified in Shopify, not Klaviyo), net list growth against unsubscribes, and per-flow RPR measured against the benchmarks above. That cadence covers everything without turning you into a full-time analyst.
Klaviyo metrics: next steps
The operators who win with email don't track more numbers. They track truer ones. Rank everything by revenue per recipient, build segments on clicks and purchases, use open rate as a smoke alarm, and let Shopify referee what email actually earned. Five metrics weekly, three checks monthly, and you'll know more about your email program than most brands learn in a year.
If your numbers sit below the benchmarks in this guide and you're not sure which lever to pull first, that's exactly what a Klaviyo audit is for. We'll show you where the revenue is leaking and what it's worth to fix it. Or just book a call with CartStrings and bring your dashboard.
Frequently Asked Questions
What is a good open rate in Klaviyo?
The average campaign open rate is 31% across the 183,000+ brands in Klaviyo's 2026 benchmarks, and the top 10% of brands exceed 45.1%. Treat your open rate as directional rather than exact, because Apple's Mail Privacy Protection auto-fires opens. A sustained drop below your own baseline matters more than the absolute number.
What is a good click rate?
A good Klaviyo campaign click rate is 1.69% or higher, which is the cross-industry average in Klaviyo's benchmark data. Flow emails average 5.58% because they respond to subscriber behavior. Klaviyo calculates click rate as unique clicks divided by delivered emails, so repeat clicks from one person only count once.
What is revenue per recipient?
Revenue per recipient (RPR) is the attributed revenue from an email divided by the number of people who received it. It's the best single measure of email quality because it combines engagement and conversion in one number. Klaviyo's benchmark data puts the average abandoned cart flow at $3.65 RPR, while the top 10% of brands earn $28.89.
Why is my Klaviyo open rate so high?
Apple's Mail Privacy Protection automatically fires open events for subscribers using Apple Mail, whether or not they read the email. Litmus data shows Apple clients account for about 49.29% of opens, so a large share of recorded opens are machine-generated. If your open rate seems inflated, build your engaged segments on clicks and purchases instead.
How does Klaviyo attribute revenue?
Klaviyo uses last-touch attribution within a configurable window: if a subscriber opens or clicks a message and then purchases inside that window, the message gets credit. This means Klaviyo-attributed revenue can overlap with other channels' reporting. Cross-check it against Shopify's sales-by-channel report monthly to see what email truly drove.
