Klaviyo vs Brevo for Ecommerce: Which Fits Your Store?

Quick verdict: if your store has meaningful order volume and you want AI that predicts what a specific customer will do next, Klaviyo's deeper, purchase-history-driven personalization is worth the higher price. If you want email, SMS, and basic CRM bundled into one low-cost plan — especially if your list is large but you don't email it constantly — Brevo is the more budget-friendly fit for most small and mid-size stores. Here's how the two actually compare for running ecommerce email.
Klaviyo was built ecommerce-first from day one. Brevo, formerly known as Sendinblue, started as a broader marketing and transactional-email platform and added ecommerce features on top — a different starting point that shows up in pricing structure, AI depth, and how deeply either tool reads your Shopify data.

Round 1: pricing and how it scales
This is where Brevo's model genuinely diverges from most ecommerce ESPs. Several of its plans bill primarily by how many emails you send per month, not by contact-list size — so a store with a large list it only emails occasionally (say, a win-back segment contacted a few times a year) can end up paying meaningfully less than it would on a platform that charges by profile count. Klaviyo prices the opposite way: by contacts, which climbs quickly as your list grows regardless of how often you actually email it. For a store sending frequent campaigns to an engaged list, that difference narrows; for one with a big, quiet list, Brevo's structure can be the cheaper path by a wide margin.
Round 2: AI and personalization depth
Klaviyo's AI reads your store's actual purchase history to flag predicted customer lifetime value, score churn risk on individual subscribers, and assemble product-recommendation blocks pulled live from your catalog — insights that plug straight into automated flows like a win-back email that only fires for customers the model actually flags as at risk. Brevo's AI tools are narrower: content generation for subject lines and email copy, plus send-time optimization based on engagement data, without an equivalent to Klaviyo's predictive, order-history-driven modeling. If predictive targeting is the specific reason you're comparing AI email tools, this round goes clearly to Klaviyo.
Round 3: ecommerce data depth and platform scope
Klaviyo's Shopify integration is deep because ecommerce is the entire reason the platform exists — order history, product catalog, and customer segments feed its AI directly. Brevo's Shopify connection covers the fundamentals (order sync, abandoned-cart triggers, segment data) competently, but it's one integration among many for a platform that also serves non-ecommerce marketers and includes transactional email and a basic CRM. That broader scope is a feature if you want one tool for more than just store marketing — but it means Brevo's AI and automation aren't purpose-built around Shopify order data the way Klaviyo's are.
Round 4: what each plan actually includes
Brevo's free tier is genuinely usable — enough to run real campaigns and basic automation with a daily send cap, which makes it a reasonable way to test the platform before paying anything. Its paid plans, starting roughly in the $9–$25/month range depending on volume and feature tier, also bundle in SMS and a lightweight CRM that most dedicated ecommerce ESPs don't include at that price. Klaviyo's free plan caps at 250 profiles rather than a send volume, and its paid tiers focus tightly on email and SMS marketing without the general-CRM extras — a narrower but deeper toolset for the one job of turning store data into revenue.
Which should you pick?
- You have real order volume and want AI that predicts customer behavior: Klaviyo. The predictive analytics and catalog-aware recommendations justify the steeper price curve.
- You're budget-conscious, have a large list you email selectively, or want basic CRM bundled in: Brevo. Its volume-based pricing and free tier make it the lower-risk starting point.
- You're not sure yet: start on Brevo's free plan to get automation running cheaply, and move to Klaviyo once order volume and list engagement are high enough that predictive personalization would meaningfully change your results. Our best AI email marketing tools for ecommerce roundup covers where both sit alongside Omnisend and Mailchimp if neither is quite the right fit on its own, and our Klaviyo vs Omnisend comparison breaks down that other budget-leaning matchup in more depth.
Whichever platform you pick, the AI drafts around whatever offer or story you give it — it doesn't invent a reason for someone to buy. If cart abandonment is the specific problem you're solving, our best AI tools for Shopify abandoned cart recovery guide compares both platforms alongside dedicated recovery tools, and since unsolicited commercial email carries real legal obligations regardless of which platform sends it, the FTC's CAN-SPAM compliance guide is worth reading before your first automated send goes out. Try Klaviyo or Try Brevo — both offer a free plan, so testing either against your own list costs nothing but setup time.
Frequently asked questions
Is Brevo good enough for a Shopify store, or is it really built for something else?
Brevo (formerly Sendinblue) started as a general marketing and transactional-email platform rather than an ecommerce-first tool, and that history still shows: its Shopify integration covers the essentials — order sync, abandoned-cart triggers, basic segmentation — competently, but without the predictive, catalog-aware depth Klaviyo builds specifically for ecommerce. For straightforward campaigns and automation on a budget, it's genuinely good enough; for a store leaning hard on AI-driven personalization, it's the shallower of the two.
Why does Brevo charge by email volume instead of contact count?
Several of Brevo's plans price primarily by how many emails you send per month rather than by the size of your contact list, which is the opposite of how Klaviyo and most ecommerce ESPs price. That structure favors a store with a large list it emails selectively — say, a big win-back segment contacted a few times a year — over one that sends frequent campaigns to its whole list, where a per-send model can actually cost more than a per-profile one.
Does Brevo have the same predictive AI features as Klaviyo?
Not at the same depth. Klaviyo's AI runs on your store's order history to flag predicted customer lifetime value and churn risk and to assemble catalog-aware product recommendations. Brevo's AI tools lean toward content generation — subject lines, email copy — and send-time optimization based on engagement patterns, without an equivalent to Klaviyo's purchase-history-driven prediction models.
Can I migrate from Brevo to Klaviyo later without losing my list?
Yes. Both platforms support standard CSV export and import for contacts, tags, and segment data, so the list itself isn't the hard part of switching. The real cost is rebuilding your automation flows — welcome series, cart recovery, post-purchase sequences — inside Klaviyo's flow builder, which takes real setup time regardless of how clean the data migration is.
