Klaviyo vs revenu: email marketing platform or full customer journey system?
8 July 2026 · by Adam Pilakis, founder of revenu
Quick summary
Choose Klaviyo if you run an ecommerce store and email and SMS revenue is the game: abandoned carts, flows, segmentation and predictive analytics are its home turf. Choose revenu if you run a service business where the money moves through phone calls, bookings and follow-up, because an email platform can't answer the phone that's ringing out right now.
- Klaviyo is the ecommerce email and SMS leader, used by more than 169,000 companies, with deep Shopify integration and predictive analytics
- revenu is a full business system: AI receptionist, missed call text-back, CRM, bookings, follow-up, reviews, reactivation and your website, built into your business
- Klaviyo's free plan covers 250 contacts; paid plans scale with your list, and since February 2025 you pay for every reachable contact, emailed or not
- revenu is a flat $599 + GST a month in AUD, with the build done for you
- Fair warning: if you sell products from a cart, Klaviyo is probably your answer, not revenu. This article says so plainly
Your business might not need more software. It might need fewer leaks.
This is the cleanest category split in the whole comparison series. Klaviyo and revenu barely compete, because they're built for two different kinds of business, and the fastest way to waste money is to buy the one built for the other kind. So let's sort out which business you're running, honestly, in the next two minutes.

What Klaviyo does well
Inside its lane, Klaviyo is about as good as it gets. More than 169,000 companies run it, and for ecommerce brands it's the default answer for a reason: the Shopify and WooCommerce integrations run deep, the segmentation is genuinely sophisticated, and the automation flows, abandoned cart, browse abandonment, post-purchase, win-back, are the revenue engine of half the online stores you've bought from.
The data side is the quiet weapon. Unified customer profiles with full purchase history, predictive analytics like lifetime value and churn risk, AI-generated segments and content, and reporting that ties every send to dollars. SMS and email run from one place on shared flows, and the free plan, 250 active profiles, 500 sends a month, 150 SMS credits, is a genuine no-cost way to start.
If your revenue lives in a cart and a customer list, Klaviyo has earned its crown. I'm not going to pretend otherwise.
03 — The honest limits
Where Klaviyo may not be enough
Start with the billing change everyone's still discovering. On 18 February 2025, Klaviyo switched to charging for active profiles: every contact you can reach, whether you've emailed them in the last year or not. Before that, you paid only for the contacts you actually messaged. The practical effect: a business with 20,000 contacts that emails 8,000 of them now pays at the 20,000 tier until it prunes the list. Klaviyo capped the initial jump at 25% for existing customers, but list hygiene is now a line item, and "why did my bill go up?" became one of the most-asked Klaviyo questions of the past year.
Then the curve. Plans start friendly, around $20 USD a month past the free tier, but scale hard with list size: roughly $150 at 10,000 profiles, $400 at 25,000, $720 at 50,000, with SMS billed separately on credits priced per country, and Reviews sold as its own add-on priced by monthly orders. The features don't change as you climb; only the bill does.
And the category limit, the one that matters most here: Klaviyo works on people already in your list. The tradie's missed call, the clinic's 9pm website enquiry, the quote from last Tuesday that nobody chased, none of those are in any list yet. There's no AI answering your phone, no missed call text-back, no booking calendar, no job pipeline. For a service business, the leaks happen before an email address ever gets captured, which is precisely where an email platform can't reach.
None of that makes Klaviyo overpriced or overrated. It's the shape of the category: brilliant at monetising a list, blind to the phone.
04 — The other side
Where revenu is different
revenu is built for the business where the money rings. The critical moment isn't an abandoned cart at 11pm, it's a missed call at 11am while you're on the tools or with a client, and that's where the system starts.
One login covers the whole connected stack: enquiry capture from your website and socials, missed call text-back within seconds, an AI employee answering calls and messages in your tone, CRM and pipeline, bookings and payments, SMS and email follow-up (yes, revenu sends email campaigns too), database reactivation, review requests, your website and funnels, and reporting. The framework behind the build is the rhythm: plug the holes first, then turn the tap on.
And nobody hands you a flow builder and wishes you luck. I build the system with you, around your process: live after the first 45-minute session, fully built over three sessions inside 14 days, with the build valued at $3,000 to $5,000 included, then support and a monthly showcase call as part of the price.
The one-line version
Klaviyo turns a customer list into revenue. revenu turns a ringing phone into customers.
different leaks, different plumbingPicture the two critical moments side by side. An online store's customer abandons a cart at 11pm; Klaviyo's flow fires overnight and recovers the sale by breakfast. Perfect tool for that job. Now a plumber's phone rings at 11am, mid-job, and rings out; the caller dials the next plumber on Google and books them instead. No email flow on earth fires for that moment, because there's no email address yet. revenu's text-back and AI employee exist for exactly that ten-second window. Same principle, automation catching the leak, aimed at completely different leaks.
05 — The money
Klaviyo pricing vs revenu pricing in Australia
Klaviyo, as listed at July 2026 in USD: free for up to 250 active profiles (500 email sends and 150 SMS credits a month, email support for the first 60 days), then the Email plan from around $20 a month at 500 contacts, scaling with list size to roughly $150 at 10,000, $400 at 25,000 and $720 at 50,000. Email + SMS plans add more, SMS runs on per-country credits, and Reviews bills separately by monthly orders. Since February 2025, every reachable contact counts toward the bill, emailed or not. Check Klaviyo's pricing page for current tiers.
revenu is $599 + GST a month, flat, in Australian dollars, plus a $500 build fee up front (waived when a current client refers you). That includes the full build, an AI employee trained on how you work, your website or funnel, ongoing support and the monthly showcase call. Month to month, no lock-ins. Usage costs apply for calls, SMS, email and AI activity, with live usage pricing in AUD here, and there's an unlimited AI option to keep AI costs predictable.
The pricing shapes tell the story: Klaviyo's bill grows with your list because the list is the asset it monetises. revenu's price stays flat because the asset it protects is every enquiry that was about to leak. Match the pricing shape to where your revenue actually lives.
06 — The decision
Choose Klaviyo if, choose revenu if
Choose Klaviyo if: you run an ecommerce store, revenue moves through carts and a customer list, you or your marketer will own the flow builder, and abandoned cart recovery, segmentation and predictive analytics are the growth levers that matter.
Choose revenu if: you run an Australian service business, enquiries arrive by phone, web form and DM, the leaks happen before anyone's on a list, and you want AI answering in seconds, bookings flowing, and follow-up running, built with you at one flat AUD price.
07 — Final verdict
The verdict
If you sell products from a cart, choose Klaviyo. It's the best in its category and revenu isn't trying to take that crown.
If you sell your time, your trade or your expertise, the leak isn't in your email list, it's at your front door: the calls, the enquiries, the follow-up nobody has time for. That's the system revenu builds. Weighing all-in-one platforms instead? The Keap comparison covers the email-first automation lane, and HubSpot covers the big-platform end of the same decision.

08 — FAQs
Klaviyo vs revenu FAQs
Is Klaviyo free?
Up to a point. Klaviyo's free plan covers 250 active profiles, 500 email sends and 150 SMS credits a month, with email support for the first 60 days, and it stays free as long as you stay under those limits. Cross 250 contacts and you move to paid tiers, starting around $20 USD a month and scaling with list size.
Why did my Klaviyo bill go up?
Most likely the February 2025 billing change. Klaviyo now charges for every active profile, meaning every contact it can reach, whether you've emailed them recently or not. Before, you paid only for contacts you actually messaged. Suppressing contacts who haven't engaged in 6 to 12 months is the main way to bring the bill back down.
Is Klaviyo only for ecommerce?
Not exclusively, but it's built around ecommerce: the deep integrations, abandoned cart flows, predictive lifetime value and revenue reporting all assume a store and a customer list. Service businesses can technically use it for newsletters, but the moments where service businesses leak money, missed calls and unanswered enquiries, sit outside what any email platform does.
What is the best Klaviyo alternative in Australia for service businesses?
If you're a service business looking at Klaviyo, the honest answer is you're probably in the wrong aisle. The leaks in a service business happen before anyone joins an email list: the missed call, the slow reply, the unchased quote. A connected system like revenu, with AI response, AU phone and SMS, bookings and follow-up, fits that job.
Does revenu replace Klaviyo?
For a service business, yes: revenu covers email and SMS campaigns alongside the CRM, AI employee, bookings, reviews and reactivation, in one login. For a genuine ecommerce store, no: Klaviyo's cart flows and store integrations are its home ground, and revenu isn't built to out-Klaviyo Klaviyo there.
Can revenu work with Klaviyo?
Yes. Businesses with both a store and a service arm sometimes keep Klaviyo for ecommerce flows and use revenu for the service side: AI answering enquiries, missed call text-back, bookings and follow-up. We design the split together so each system owns its lane and your customers never get double-messaged.
