Based on published reviews and hands-on use across common tasks, not a single synthetic score.
Brevo vs Klaviyo is a choice that looks small on paper and turns out to be a big one once your list starts growing. Both platforms send email and SMS, both automate follow-ups, and both have free plans. But they charge you in completely different ways, and that single difference can move your monthly bill by hundreds of dollars.
So here’s what this guide covers: what each tool actually does, how the pricing really works, where each one is strong, and who should pick which. No hype, just the trade-offs that matter.
Here’s the quick comparison before we get into details.

If your store lives and dies by email revenue, Klaviyo is built for you. If you want solid tools at a lower and more predictable cost, Brevo is usually the smarter start.
A lot of people land here asking what is Klaviyo, so let’s clear it up. Klaviyo is a marketing automation platform built mainly for online stores. It connects to your shop, such as Shopify or WooCommerce, and pulls in real customer data: what people viewed, what they added to their cart, what they bought, and when.
Then it lets you act on that data. What does Klaviyo do with it? It sends targeted emails and text messages, runs automated flows like abandoned cart reminders and welcome series, splits your audience into very specific segments, and shows you how much revenue each message earned. That revenue tracking is a big reason stores love it, because you can see which emails actually made money instead of guessing. The trade-off is that all this depth comes with a learning curve and a price tag that rises with the size of your list. Klaviyo rewards stores that use it heavily, and it can feel like overkill if you only send the occasional newsletter.
Brevo, which used to be called Sendinblue, takes a broader and simpler approach. It’s an all-in-one platform with email marketing, SMS, WhatsApp campaigns, a built-in CRM, and transactional email for things like receipts and password resets. It isn’t aimed only at stores, so it fits blogs, service businesses, and agencies just as well.
The Brevo plans are easy to follow. There’s a free plan, then Starter, Standard, and Professional tiers, plus custom Enterprise pricing. Prices start at roughly $9 a month for Starter and about $18 for Standard, and the Professional plan sits around $499 a month for very high send volumes. These numbers change, so double-check the current Brevo plans on the official Brevo site before you commit.
Yes, and it’s one of the better free plans around. Brevo lets you send up to 300 emails a day, which is roughly 9,000 a month, and it doesn’t punish you for having a large contact list. Klaviyo’s free plan is far tighter, capping you at 250 profiles and 500 emails a month. If you’re just starting out or building a list, that gap matters. The catch with Brevo’s free plan is the daily send limit and Brevo branding on your emails, which you can remove on a paid plan.
This is where the Brevo vs Klaviyo decision usually gets made. Brevo charges based on how many emails you send each month, and contacts are cheap or free to store. Klaviyo charges based on how many active profiles you have, no matter how often you email them. Picture a list of 50,000 people that you email twice a month. On Brevo, that’s a modest bill, often somewhere around $80 a month by some estimates.
On Klaviyo, the same list can run roughly $700 or more a month. Flip the situation, though, and the story changes. If you email a small list constantly and rely on deep ecommerce segmentation, Klaviyo’s price starts to feel more reasonable because you’re using what you pay for. The honest takeaway is simple. Big list and low send volume favors Brevo. Small list, heavy sending, and a store that earns real revenue from email favors Klaviyo. Always run the math on your own numbers, because both companies adjust their pricing from time to time.
On everyday features, the two are closer than you’d think. Both offer drag-and-drop email builders, templates, automation flows, segmentation, A/B testing, and SMS.
Where they split is focus. Klaviyo goes deeper on ecommerce: product-level data, predictive analytics, and tight store integrations that let you build very precise campaigns. Brevo goes wider: it adds WhatsApp, push notifications, a full CRM, and transactional email in one place, which is handy if you want everything under a single login.
If you’re looking for a Brevo alternative, Klaviyo makes sense mainly when you run an online store and want that extra ecommerce muscle. If you’re not an ecommerce brand, other tools may suit you better than either one.
Most people find Brevo easier to pick up. The interface is simpler, and you can get a first campaign out quickly. Klaviyo asks for more setup, though the payoff is stronger targeting later.
On ratings, both score well. On Capterra, each sits at about 4.6 out of 5, with Brevo having far more reviews than Klaviyo. If you read Klaviyo reviews and Brevo reviews, a few themes repeat. Users praise Brevo’s generous free plan and simple tools, but a few mention that its spam filtering can be strict. Klaviyo gets praise for its ecommerce power, while complaints often center on rising costs and support that some users find slow. Reviews are personal, so use them as a guide and not a verdict.
Automation is where Klaviyo earns its reputation. Its flows can react to what a shopper did a few minutes ago, such as viewing a product, leaving a cart, or buying for the third time, and then send a message built around that exact moment. Brevo’s automations are easier to set up and cover the common needs well: welcome emails, follow-ups, and simple triggers based on contact activity or website behavior. They’re less detailed on product-level data, but most small businesses never miss it.
Integrations are strong on both sides. Klaviyo plugs deeply into Shopify and other store platforms, while Brevo connects with WordPress, WooCommerce, and a wide range of other tools. In the Brevo vs Klaviyo matchup, the question isn’t who has more integrations, but whether the ones you need work well with your setup.
Keep it simple when you make the Brevo vs Klaviyo call:
Yes. Brevo has a free plan that lets you send up to 300 emails per day with a generous contact allowance. It includes basic email and automation tools, with limits on daily sends and Brevo branding that you can remove on a paid plan.
Klaviyo is a marketing automation platform, mostly for ecommerce. It connects to your store, uses customer behavior data to send targeted emails and SMS, runs automated flows like abandoned cart messages, and reports how much revenue each campaign earned.
For most people, Brevo is cheaper, especially with a large list and low send volume, because it charges by emails sent. Klaviyo charges by profiles, so costs climb as your list grows. Check both pricing pages for current numbers.
Klaviyo is generally the stronger fit for Shopify stores that rely on email for sales, thanks to its deep store integration and revenue tracking. A smaller store on a tight budget may still do fine with Brevo.
The Brevo vs Klaviyo choice comes down to your business, not a winner’s trophy. Brevo gives you more for less and keeps things simple. Klaviyo costs more but rewards serious ecommerce brands with deeper data. Try the free plan on each, send a real campaign, and let your own results decide.
