Klaviyo charges for active profiles — every contact you could still reach — whether you email them or not. That single mechanic drives the entire bill. A store holding 25,000 profiles pays roughly $400 a month even if it only mails 5,000 of them, which makes deleting unengaged contacts one of the highest-return things an ecommerce marketer can do.
- What it is: The leading ecommerce marketing automation platform, combining email, SMS, and customer data.
- Best for: Shopify and ecommerce stores where email and SMS drive meaningful revenue.
- Pricing: Free to 250 profiles. Reported at ~$20 at 500 contacts, $100 at 5,000, $400 at 25,000. SMS billed separately.
- The honest catch: The steepest step is in the middle — reportedly $150 to $400 between 10,000 and 25,000 profiles.
What Is Klaviyo?
Klaviyo is the default answer for ecommerce email and SMS, and its dominance rests on data rather than sending. It ingests every event a store generates — products viewed, carts abandoned, orders placed, refunds issued — and makes them addressable in segments and flows. The result is automation that knows what someone bought, when, and what they looked at afterwards.
That depth is why it wins against general email tools for stores. Abandoned cart, browse abandonment, post-purchase, replenishment, and win-back flows all work better when the platform holds the commerce data natively rather than syncing it. Revenue attribution per flow follows from the same foundation, and it is what makes Klaviyo defensible at its price.
The platform has broadened considerably. Alongside Marketing, the pricing page now lists Data + Analytics, Service, Composer, and Customer Agent as separately priced products — so Klaviyo in 2026 is a suite you assemble rather than a single subscription.
How Klaviyo Works
- Billed on active profiles. Contacts you can still reach, regardless of whether you send to them.
- Email and SMS priced separately. SMS is an additional line on top of the email plan.
- A genuinely free tier. 250 profiles, 500 emails a month, and $5 of mobile messages.
- Deep commerce integration. Native connections to Shopify and other platforms, ingesting events rather than just contacts.
- Revenue attribution per flow. The reporting that justifies the cost to a finance team.
- Multiple priced products. Marketing, Data + Analytics, Service, Composer, and Customer Agent assemble into one total.
Klaviyo Pricing
The free plan is published; paid pricing sits behind a calculator. Figures below are third-party reported for July 2026.
| Active profiles | Reported email cost |
|---|---|
| 250 | Free (500 sends/month) |
| 500 | ~$20/month |
| 1,000 | ~$30/month |
| 5,000 | ~$100/month |
| 10,000 | ~$150/month |
| 25,000 | ~$400/month |
What actually determines your bill:
- You pay for reachable contacts, not activity. This is the mechanic everything else follows from. A profile that has not opened an email in two years costs the same as your best customer. Pruning unengaged profiles is a direct, immediate cost reduction — and usually improves deliverability at the same time, which makes it the rare optimisation with no downside.
- The middle of the curve is where it hurts. Reported pricing moves from about $150 at 10,000 profiles to $400 at 25,000 — a 167% increase for 150% more contacts. Growth costs more than proportionally exactly where most successful stores are heading.
- SMS is a separate bill. Roughly $45 for 5,000 US messages on top of the email plan, so a 10,000-profile store running both is nearer $195 than $150.
- The free tier is real but tiny. 250 profiles and 500 monthly sends is enough to build flows and validate the integration, not to run a store.
- The platform is now modular. Data + Analytics, Service, Composer, and Customer Agent are priced separately, so “what does Klaviyo cost” increasingly depends on which products you assemble.
- Paid pricing is calculator-only. There is no published table, so comparison requires configuring your own scenario.
Who Should Use Klaviyo
- Ecommerce stores with real revenue. The clearest case. Where flows drive meaningful sales, Klaviyo’s data depth pays for itself.
- Shopify merchants. The integration is the deepest in the category and the reason Klaviyo became the default.
- Teams running email and SMS together. Unified profiles across both channels genuinely help.
- Anyone who needs revenue attribution. Per-flow revenue reporting is what justifies the spend internally.
It fits poorly for newsletters and content businesses, where Kit costs far less and fits better; for large, rarely-mailed lists, where profile-based billing is the worst possible model; and for stores just starting out, where Omnisend offers similar capability with a more forgiving free tier.
Honest Pros and Cons
Strengths
- The best ecommerce data model in the category. Events, not just contacts.
- Excellent revenue attribution. Per-flow reporting that answers the commercial question.
- Deep Shopify integration. The strongest native connection available.
- Email and SMS on unified profiles. Genuinely useful rather than two products bolted together.
- A real free tier. 250 profiles is small, but permanent and functional.
- Category-leading flows. Abandoned cart and post-purchase automation are the benchmark.
Limitations
- You pay for contacts you never email. Profile-based billing punishes large dormant lists.
- Steep mid-curve escalation. Reportedly 167% more between 10,000 and 25,000 profiles.
- SMS costs extra. A separate and meaningful line item.
- No published price table. Paid pricing requires the calculator.
- Increasingly modular. Five separately priced products complicate the total.
- Expensive against general email tools. Justified only if you use the commerce depth.
Klaviyo Alternatives and How It Compares
- Omnisend is the closest ecommerce competitor, generally cheaper with a more generous free tier.
- Drip offers ecommerce automation with no feature gating at all, at a flat $39 entry.
- Kit is far better for creators and newsletters, free to 10,000 subscribers.
- ActiveCampaign goes deeper on B2B and complex behavioural automation.
- MailerLite and Brevo cost a fraction for straightforward email, without the commerce data layer.

The Verdict
Klaviyo earns its position. For an ecommerce store, the difference between an email tool that holds contacts and one that holds every purchase, view, and cart event is the difference between sending campaigns and running automation that knows what someone actually did. The Shopify integration is the deepest available, the flows are the category benchmark, and per-flow revenue attribution answers the only question that matters when someone asks whether the tool is worth its cost.
The thing to internalise before committing is what you are being charged for. Klaviyo bills on active profiles — every contact you could still reach — regardless of whether you email them. A dormant subscriber from three years ago costs exactly what your best repeat customer costs. That makes list hygiene a genuine financial lever rather than a housekeeping chore: deleting profiles you will never successfully re-engage reduces the bill immediately and usually improves deliverability, which is an unusually clean win. Do it before every renewal.
Watch the middle of the curve especially. Reported pricing rises from around $150 at 10,000 profiles to $400 at 25,000 — steeper than proportional, and precisely the range a growing store passes through. Add SMS as a separate bill on top, and the total for a 10,000-profile store running both channels is closer to $195 than $150. None of that makes Klaviyo bad value if the flows are producing revenue; it does mean you should model your cost at the list size you expect in a year rather than the one you have, and check whether Omnisend or Drip cover your actual use case for less.
FAQ
How much does Klaviyo cost?
The free plan covers 250 active profiles, 500 email sends per month, and $5 of mobile messages. Paid pricing sits behind a calculator rather than a published table; third-party sources report roughly $20 per month at 500 profiles, $30 at 1,000, $100 at 5,000, $150 at 10,000, and $400 at 25,000. SMS is billed separately, at roughly $45 for 5,000 US messages.
What is an “active profile” in Klaviyo?
A contact you can still reach — someone who has not unsubscribed or bounced permanently. Klaviyo bills on this count regardless of whether you actually email them, so a subscriber who has ignored you for years costs the same as an active customer. This is the single most important thing to understand about Klaviyo’s pricing, and it makes deleting unengaged profiles a direct cost saving.
Where does Klaviyo’s pricing get expensive?
In the mid-range. Reported figures rise from about $150 per month at 10,000 profiles to $400 at 25,000 — a 167% increase for 150% more contacts, so cost grows faster than list size exactly where most growing stores are heading. Adding SMS increases it further, since that is billed separately on top of the email plan.
Is Klaviyo’s free plan enough to start with?
To build and validate, yes; to operate, no. It covers 250 active profiles and 500 email sends a month, which is enough to connect your store, construct flows, and confirm the integration works properly before paying. Any store with real traffic will exceed 250 profiles quickly. Omnisend’s free tier is more generous if you need longer at zero cost.
What is Klaviyo best for?
Ecommerce stores — particularly on Shopify — where email and SMS drive measurable revenue and flows are built on purchase and browsing behaviour. Its data model and revenue attribution are the best in the category. It is a poor fit for newsletters and creator businesses, for large lists that are rarely emailed, and for stores that only need broadcast campaigns.

HONEST. This company is HONEST. They don't try to catch you into a contract, they don't over sell you, they are helpful, they provide documentation for everything. My company has a dedicated account manager and she is the greatest asset to me, my team and in turn, the company I work for.
When my developers refuse to read all the blatantly easy to understand documents that Klaviyo provides - and come back to me asking for more information. Nothing.
We are able to launch so many different types of marketing campaigns that we weren't able to do with our previous CRM platform.
Ease of use, the simple interface and the multitude of things you can do. I love the super easy segmentation, drag'n'drop editor, Facebook integration and much more
I really would like workflows to be more advanced. Right now they only trigger email activity - but it would be nice to have workflows operate internal maintenance on customer properties etc. Like "Property A is set to XY - then set Property Z to XY" or similar
Super simple email follow ups, campaigns, tracking etc for an ecommerce store selling wine.
Everything is easy to use, you can segment lists.
nothing, the klaviyo team always goes above and beyond especially in customer service
list segmentation
Seamlessly integrates with Shopify and allows you to target emails based on specific customer behavior. Intuitive to use.
Once, the software had a bug where it deployed a message on the wrong day - although it was scheduled for a date weeks in the future.
All of the brands I work with are able to test which messaging their customers respond to best, and they're able to win back lapsed customers, even on items that you wouldn't buy often.
Klaivyo E-Mail Marketing is designed to keep your stress levels down, value up, and make you look like a marketing genius in the process. As an agency powering 100's of client accounts, our responsibility is to consult our clients on the best eco-system of marketing tools, processes, and platforms. Klaviyo fits into this eco-system as a 'No Brainer' component that any SMB or Mid-Market Company can use successfully from Day 1. The learning curve is tiny, while the features and capabilities are almost endless.
Truth be told, this is one area where normally I can list about a dozen or so issues on any system or platform we own licenses for. In the case of Klaviyo, there literally are no 'Cons' to speak of. So I guess I'm going to write about being a fan of hamburgers or something because there's really no other use for this box other than that. Klaviyo is literally THAT GOOD!
As an agency, our ecosystem of SMB and Mid-Marketing clients are always looking for consulting on 3rd Party Applications, Systems, and Demand Generation Processes that provide a high-yield ROI. Klaviyo delivers each and every time. The system essentially sells itself, while making the agency team look good in the process. Exceptionally strong, powerful, intuitive, and simple.
Klaviyo has really grown on us over time. We sell products on our shopify store and Klaviyo integrates directly with them. This allows you to get up and running within minutes. It also allows them to obtain crucial data such as revenue and customers details. This is then used to show you the revenue per email (one of my favorite features) so you know the ROI ont hese. It also has many new features such as sending emails basd on shopping conditions (a lot of email providers won't have this because their not designed for ecommerce) i.e. if they browsed for a product, they get a series of emails about that product. This is very advanced stuff!
At first I thought the price was a bit high, but I think it's worth it for what you get with them. They have really great customer support and they have a ton of features.
One of the big problems we have is that most people are buying our product only once, and our cheapest product. Therefore we have a need to increase the LTV of the customer. Email marketing helps us offer more upsells, increase engagement and understand our customers better. Klaviyo helps us do that with all their features.
The dashboard is great at giving you an overall glance of how well our campaigns are performing.
Email template builder is a bit limited.
Email marketing ROI - determining which campaigns are working and having a clear understanding of ROI.
I love that the software can act like a CRM AND as an ESP. It integrates with Shopify seamlessly and allows you to be in contact with your customers through their lifecycle (pre-purchase, post-purchase, lapsed, etc) automatically without your continued effort.
The out of the box templates were not as great as I needed (we transitioned from Mailchimp), so we ended up using our graphic designers to design the emails and hired email developers to write the code for the emails. Klaviyo has a lot of very powerful variables, and can be confusing for a beginner or non-email tech like myself, so again, we hired professionals to handle the workload of setting up the email flows and getting the technical details correct.
14% of our monthly revenue is due to a robust automated email marketing program via klaviyo flows. As I mentioned above Klaviyo allows us to be in contact with our leads and customers wherever they may in the customer lifecycle.
Built from the ground up for e-commerce. Everything else I used before doesn't make sense anymore.
Email templates builder could be better. Interface lacks basic functionality. Undo would be nice for starters.
Klaviyo is allowing us to create incredibly specific segments based on our e-commerce customer data including behaviour on the site.
It is super easy to use, the automated flows are amazing, and we've received amazing support every step of the way.
Can't think of anything I don't like. We haven't had any issues.
The automation aspect is great, it makes it very easy and our conversion rate has already gone up in just the first month of use.
We used another email client for a while before using Klaviyo and the difference is night and day. I love the way I can immediately see how well my account is doing and the power of the segmentation is amazing.
Honestly I don't really have a any dislikes - Its a powerful email tool that has far exceeded our return on investment
We needed a more robust and easier email service that just worked and increased our ROI for every email sent and that's what Klaviyo has done for us
It integrates very nicely and easily with Shopify, including the ability to pull some analytics for customer segmentation and an 'abandoned' email recovery cart feature. Also love the different flows you can set up depending on different parameters. Email support has also been relatively good and responsive.
Price - once you've sent out over 100 or 200 test emails (if I recall correctly), you'll have to start paying to send out more test emails for your future campaign even if you haven't reached the 500 email list threshold for the next pricing tier.
We need a robust email system that integrates easily with Shopify to market and communicate with our customers. Ease-of-use and efficiency is key. Klaviyo has enabled us to do all of the above.
I love that the options are endless. You can create any flow you can think up!
Nothing. We love the software! We recommend them to anyone
Speaking to our customers as individuals not as a crowd.
This program has almost limitless abilities for customization, timing, and safety features to ensure the customers are treated in a courteous manner. Amazing metrics for analyzing customer behaviors.
It is not the most intuitive software. It takes a bit of time to learn it, but once you get the hang of it there are an amazing amount of marketing possibilities provided to you.
This is helping us understand the demographic and interests of our customers. We are able to use this information to target our marketing to the appropriate groups of people, thus saving money and making our advertising more effective.
Klaviyo is awesome, particularly for ecommerce companies. I especially like how you can set up automated drip campaigns. Setting up rules around automated emails is intuitive and easy. I've used both Mailchimp & Marketo - Klaviyo wins hands down. The platform has a lot of pre-built integrations and is great if you run your ecommerce store on Shopify. Another cool feature is the ability to see individual profile activity.
The email template builder needs some love. It's not as robust as the Mailchimp email builder but it's still pretty easy to use as long as you can live with some limitations.
The way the platform is built around individual profiles helps a lot with attribution.
Their deep integration with Shopify is the main attraction for us to use their software, as well as we saw a few very successful brands already using them.
Could use tagging, and in-email click triggers that allow for further segmenting/tagging.
This really helped us simplify our email automations, from thank you's, upsells, autoresponder series to educate interested parties, abandoned cart emails, surveys and feedback from customers... and more.
I love that it integrates with our Big Commerce store and gives us transactional information, which we didn't get from Mailchimp. I also appreciate how easy it is to set up the different flows, and that they have out of the box templates to build off of.
I wish they had a chat feature for customer service. It's a bit delayed having to wait for email responses. Having a phone option would be great too. I realize that a dedicated account manager is available once our account hits a certain number, but options other than email would be great until that time. I also wish they had emojis for subject lines on campaigns.
We wanted to have a better understanding of what our customers were doing/buying on our site, which Klaviyo has helped with tremendously. Our campaigns & flows increased our web sales by 30% in 2017. The segmentations have been the most helpful, especially allowing us the market to customers for both endurance product and lifestyle product.
I love being able to send segments directly to Facebook custom audiences.
There isn't really anything I dislike about Klaviyo.
We are using Klaviyo for Email marketing for ecommerce. It allows us to segment buyers and send specific emails to those groups we customize.
Klaviyo is by far the best email marketing platform I have come across! From day one it puts your business in a place to start seeing immediate ROI. Started with MailChimp and I am so glad I made the switch!! We currently do about 15% of our online sales via referrals from Klaviyo emails.
Klaviyo is great. Any question I have had as been answered within 24 hours by their awesome support team.
We are growing an e-commerce business and the ability to keep constant contact with our customers is incredibly beneficial. The built-in analytics allow you to directly assess what works, what doesn't, and where to invest your time and energy.
It's very easy to customize and make professional without having to write the code.
I do not like the way the buttons look - especially on mobile.
How to attractively send emails to customers - receipts, sales, news, etc.
Klaviyo's customer service rocks! Jason walked me through the process so I didn't have to think about the technical aspects of my email fundraising at all. And the integration with our fundraising platform, Funraise, makes everything run smoothly.
When your list gets big, it's a bit expensive.
It's too early to tell, but we're segmenting our lists and customizing our communication.
I love the reporting! I like to see what the return is for the marketing.
Template options are not great. Would like some extra options
Utilization of marketing materials
I like the ability to build flows and the easy integration into our e-commerce website.
I'm unable to send text messages via the platform.
We've sold more event tickets and seen a 15% increase in online sales from email campaigns.
I feel Klaviyo is an extension of our retail store and content site. Before we had iContact and it felt so tired and old, but with Klaviyo all our campaigns sync easily with our promotions (we can see how much a single email created in revenue, orders placed, etc) and the flows (autoresponders) are easily linked based on on-site activity. It's so nice to have everything linked together.
Nothing. Klaviyo offers great customer support, the UI is easy and nice to look at, and like I said has awesome functionality.
Before our ESP (iContact) worked independent of our retail store and web-site activity, but now with Klaviyo we can link them together. This helped us solve massive problems of sending people emails that were irrelevant to where they were in the funnel process; but now with Klaviyo our users can skip emails as they progress through the funnel on their own and only receive emails that support their journey.
The long list of integrations allow my company to track the entire lifespan of a consumer with important details listed every step of the way.
I'd like there to be better pre-built email capture options. ie: newsletter pop-ups with numerous field options. I also wish there was an easier way to setup subscription frequency options. ie: daily, weekly, monthly emails.
The ability to better understand a consumer's interaction with my brand, and using those insights to lead to conversions further down the road.
I really like the ability to segment customers and customer lists by what the customer has done or bought so that I can give my customers the most relevant information and promotions.
The WYSIWYG editor can be a bit testy at times, but overall works well
We've been able to easily see customers that had once been loyal long time customers that have not purchased in a while and try to bring them back. We have also been able to create the most relevant campaigns for our customers based on what they like and what they purchase.
Ease of use. I could get up to speed using it in a short period of time.
There is nothing about it that I dislike at this time.
Follow-up and post selling to our retail customers
The versatility of Klaviyo is awesome. There is nothing Klaviyo cannot do for your business as it relates to email campaigns and daily, transactional emails that are needed. I think one of the values of Klaviyo that is understated is the UI. The user interface is quote easy once you get your head wrapped around the buttons and clicks. I wish more freelancers learned Klaviyo more so I can have Klaviyo working for us in ways we haven't imagined yet
They need to certify independent service companies so they can provide managed services to business owners
Our Abandoned cart issue was huge. Klaviyo solve that issue and then-some. Our abandoned cart % dropped by 40%. We also had an issue with capturing shoppers' data that were just browsing. We installed an exit pop up, used Klaviyo to capture email data and now we're building our customer database
Easy to see ROI and conduct testing, clean reporting, streamlined setup
Cannot manage multiple Shopify stores from a single account
Manage campaigns and flows in one place, integrate with Shopify and other platforms.
ability to track and implement personalized marketing campaigns based off user acquisition and behavior
