Klaviyo vs Brevo: Which Is Better for Ecommerce?

By Devyn Pukteris, Head of Email & SMS at Sweat Pants Agency.

If you are choosing between Klaviyo and Brevo, neither is simply better. They bill on opposite models, so the right pick comes down to how you sell and how often you email. Get it wrong and you either overpay to store contacts or outgrow a tool built for a different job. We run Klaviyo daily for the DTC brands we manage, and we have watched founders get blindsided by a bill they never saw coming. This comparison covers pricing, features, ease of use, support, and fit.

What's the Difference Between Klaviyo and Brevo?

Klaviyo is an ecommerce-first email and SMS platform built around Shopify data and predictive analytics. Brevo, formerly Sendinblue, is a broader marketing suite with email, SMS, WhatsApp, and a built-in CRM. The core difference is how they bill: Klaviyo charges by profiles stored, Brevo by emails sent.

That one distinction drives most of the decision, which is why we lead with it, not a price tag. Both can run the same core program; the fundamentals of DTC email do not change with the logo. What changes is the billing and the ecommerce depth.

Which Is Cheaper, Klaviyo or Brevo?

Neither is cheaper across the board, because they bill on different axes. Brevo charges by emails sent per month with high contact limits, so it favors large lists emailed infrequently. Klaviyo charges by active profiles stored, so cost tracks your audience size no matter how often you send.

The detail that trips brands up, and that most comparisons skip, is how Klaviyo defines an active profile. It is any contact Klaviyo can email, including “never subscribed” profiles auto-created when someone reaches checkout, abandons a cart, or views a product, per Klaviyo's own billing docs. A store with 3,000 real subscribers can carry 8,000 billable profiles and pay for all 8,000. That is how brands get blindsided. Half the work when we manage Klaviyo for ecommerce brands is keeping that profile count clean, so you are not paying to store people who never engage. Brevo sidesteps the problem by not billing on contacts at all; you store the list and pay only when you send. Confirm current figures on Brevo's pricing page, since both vendors changed pricing recently.

The table below is illustrative, not exact pricing. Figures are directional as of August 2026, so verify current pricing with each vendor.

Brevo's paid plans start around $9/month for 5,000 emails. Klaviyo does not publish its tier prices, so any specific Klaviyo dollar figure you see comes from community posts, not a price list.

Does Klaviyo Have Better Ecommerce Features Than Brevo?

Yes, for ecommerce specifically. Klaviyo leads on native Shopify depth, predictive analytics, and automation built around store events. Brevo covers the core flows and adds a CRM and multichannel messaging, but its ecommerce reporting and triggers are less specialized than Klaviyo's.

Klaviyo's view: native Shopify sync, predictive metrics like customer lifetime value and churn risk, product review sync, and granular segmentation. Its flows that drive revenue run on store behavior, and its SMS is built into the same ecommerce data.

Brevo's view: a capable drag-and-drop automation builder with cart and ecommerce triggers, plus a sales pipeline CRM that Klaviyo lacks. On G2, the two score nearly level on automation, 8.9 for Klaviyo and 8.8 for Brevo, so the gap is depth, not basic capability.

How Do They Compare on Ease of Use, Deliverability, and Support?

Brevo is the easier platform to learn and gets stronger support marks; deliverability is a near-draw when both are configured well. On G2, Brevo scores 9.0 on ease of use versus Klaviyo's 8.7, and 8.8 on quality of support versus Klaviyo's 8.4.

On ease of use, reviewers describe Brevo as quick to navigate and fast to launch a first campaign. Klaviyo is more powerful and steeper to learn.

On deliverability, both are reliable, and inbox placement depends more on your list hygiene and sending than on the logo. One caveat: Brevo's free and lower tiers send from a Brevo subdomain by default, with a custom domain on higher tiers.

Klaviyo vs Brevo: Pros and Cons

Category by category, this is how they split, with an overall rating for each.

Klaviyo strengths: deep Shopify integration, predictive analytics, advanced segmentation, native ecommerce SMS. Klaviyo tradeoff: cost rises with your profile count, including profiles that never opted in.

Brevo strengths: send-based pricing, high contact limits, built-in CRM, a 300-a-day free plan, easy setup. Brevo tradeoff: shallower ecommerce reporting and SMS depth, plus branding on lower tiers.

Overall: Klaviyo 4.5/5 for ecommerce, Brevo 4/5 for value and multichannel.

Is Brevo a Good Alternative to Klaviyo?

Brevo is a genuine Klaviyo alternative for budget-conscious stores, large infrequent senders, and teams that want a CRM. It is a weaker fit for brands needing deep ecommerce automation, predictive analytics, or native SMS at scale.

Migration reality: moving from Brevo to Klaviyo is a CSV export and import for contacts and consent status, and Klaviyo backfills order history through its native Shopify integration. Email engagement history from Brevo, like past opens and clicks, does not carry over, so plan a short re-warming period.

Brevo is not the only Klaviyo alternative worth weighing. Teams that want a full CRM in the same tool usually end up looking at HubSpot, while stores with simpler needs tend to land on Constant Contact.

Should I Use Klaviyo or Brevo for Ecommerce?

Use Klaviyo if ecommerce is your growth engine and you email often; use Brevo if you are early, budget-first, or email a large list infrequently. The real question is a revenue one: at what point does Klaviyo's premium pay for itself.

In our experience, Klaviyo's premium starts earning its keep once email and SMS drive a real share of revenue, usually once a store is doing roughly $20,000 or more a month and running actual flows rather than the occasional broadcast. Below that, Brevo keeps more margin in your pocket while you build the list.

Choose Klaviyo if

You run a Shopify store, email at least weekly, want predictive analytics and native SMS, and expect flows to drive a real share of revenue. Klaviyo's depth pays off when you use it: for Condition 1, aligning flows and campaigns grew BFCM revenue 679.9%.

Choose Brevo if

You email a large list infrequently, want a built-in CRM, are early or budget-constrained, or value ease of use over ecommerce depth. Do not switch to Klaviyo if your list is full of never-subscribed profiles you would be paying to store, or if you will not use its flows and segmentation. Paying for power you leave idle is the most common Klaviyo regret.

What Third-Party Reviews Say

Both review well, and the split is predictable: Klaviyo praised for ecommerce power, Brevo for value and ease.

Klaviyo: G2 rates it about 4.6/5 across 1,300-plus reviews, and Capterra sits near 4.6/5. Reviewers highlight ecommerce automation, segmentation, and the Shopify integration. The recurring complaint is that cost escalates as the list grows.

Brevo: G2 rates it about 4.5/5 across 2,500-plus reviews, with Trustpilot lower at roughly 4/5 across 7,000-plus reviews. Praise centers on affordability, ease of setup, and the no-contact-billing model. The negatives that repeat are a strict account-approval process and slower ecommerce depth. Brevo's Trustpilot score is the weaker of its marks, and we include it on purpose.
