Klaviyo vs Brevo 2026: Email Platform Guide for Cross-Border Sellers
Two completely different pricing models
The core difference between Klaviyo and Brevo isn’t features. It’s how they charge you, and that determines which one makes economic sense for your business.
Klaviyo charges by contact count. 1,000 contacts costs $20/month. 5,000 contacts is $45/month. 10,000 contacts runs about $150/month, and 50,000 contacts is roughly $700/month. The bill goes up as your list grows, regardless of how many emails you actually send.
Brevo charges by send volume. The free tier lets you send 300 emails per day (around 9,000/month). Paid plans start at $9/month for 5,000 sends to unlimited contacts, $18/month for 20,000 sends, and $25/month for 40,000 sends. Storing a large list costs nothing, as long as you aren’t blasting it constantly.
Put that in concrete terms. Say you have 20,000 contacts but only send twice a month, totaling 40,000 sends. Klaviyo would cost $300+/month at that list size. Brevo would cost $25/month.
Flip the scenario. You have 5,000 active contacts, but you run heavy behavioral automations: cart abandonment, browse abandonment, post-purchase sequences, win-back flows. Your monthly send count climbs past 150,000 easily. At that volume, Brevo’s per-send pricing adds up fast.
The short version: large list, low send frequency = Brevo is significantly cheaper. Small list, high automation trigger volume = the gap narrows, and Klaviyo’s data depth starts to justify the cost.
Shopify integration: a real gap
Klaviyo has the deepest Shopify integration of any email tool on the market. It syncs order history, SKU-level browse behavior, cart contents, time-on-page, refunds, and returns. All of this flows into each contact’s profile in real time, and automations can use any of it as trigger conditions.
To give a specific example: you can set a flow to trigger only when a user has viewed a specific SKU more than three times but hasn’t purchased, and hasn’t placed any order in the past 90 days. You can branch that flow based on the item’s price, current inventory, or product category. That’s the depth of what’s available natively.
Brevo has a Shopify plugin and covers the basics: order completed, cart abandoned, customer registered. But building Klaviyo-style behavioral segmentation in Brevo usually requires configuring webhooks or adding a third-party connector. For sellers without a developer on hand, that’s a meaningful barrier.
If your primary use case is a Shopify store with behavior-triggered flows, cart abandonment recovery, or churn prediction, Klaviyo’s integration depth is a genuine advantage. If you’re selling across multiple platforms or your email program is mostly scheduled campaigns rather than triggered flows, Brevo’s flexibility works better.
AI feature comparison
| AI Feature | Klaviyo | Brevo |
|---|---|---|
| Predicted customer lifetime value (CLV) | ✅ Built in, segmentable | ❌ Not available |
| Churn risk prediction | ✅ Supported, auto-segmentable | ❌ Not available |
| AI audience builder (natural language) | ✅ Added in Spring 2026 Edition | ❌ Not available |
| Send time optimization | ✅ Per-contact | ✅ Supported |
| AI email content / subject line generation | ✅ Supported | ✅ Supported |
| A/B testing automation | ✅ Multivariate | ✅ Supported |
Klaviyo’s predicted CLV is the feature that actually changes how you allocate budget. It estimates each contact’s spending potential over the next 180 days based on purchase frequency, average order value, and recency. You can segment by predicted CLV and, for example, restrict discount codes to high-value segments instead of broadcasting them to everyone.
Brevo doesn’t have predictive analytics. Its AI covers send time optimization and content assistance. If you don’t use predictive modeling in your decision-making, this difference won’t matter much in practice.
SMS support
Both platforms support SMS, but they target different markets. Klaviyo’s SMS is primarily built for the US and Canada, and it integrates cleanly within the same automation flows as email. An abandonment flow can send an email, wait 24 hours, then send a follow-up SMS if the contact doesn’t convert. The cross-channel sequencing feels native.
Brevo’s SMS covers more countries globally, with better reach across Europe, Southeast Asia, and other regions. If your main markets are outside North America, Brevo’s SMS coverage is more practically useful.
Templates and design
Brevo has more templates out of the box. Most promotional scenarios have something ready to adapt: seasonal promotions, new product launches, welcome series, reengagement campaigns. The drag-and-drop editor is straightforward and doesn’t require much setup time.
Klaviyo has fewer starting templates but gives you more control once you’re inside the editor. Dynamic content blocks, conditional sections based on contact attributes, and product recommendation components can all be embedded directly. For sellers with email design experience, Klaviyo’s ceiling is higher. For sellers just getting started, Brevo’s template library gets you to a working email faster.
How to choose
Brevo makes more sense if:
- Your list is over 20,000 contacts but you send infrequently (1-2 campaigns per month)
- Your email program is mostly batch campaigns, not behavioral triggers
- Your primary markets are in Europe or Southeast Asia
- You’re starting out and want a low-cost entry point
Klaviyo makes more sense if:
- You run a Shopify store and want automation built on purchase behavior
- You rely on cart abandonment, churn prediction, or predicted CLV features
- Your list is under 10,000 contacts but you send heavy trigger-based flows
- You’re willing to invest time setting up detailed automation
There’s a middle category worth calling out: mid-sized independent stores with 30,000 to 50,000 contacts that mainly run batch EDMs with occasional triggers. For these sellers, the decision is mostly financial. Run the numbers with Brevo’s send-volume pricing, then run them with Klaviyo’s contact-count pricing. Whichever is cheaper for your actual send pattern is probably fine. At that scale, the feature gap is real but unlikely to swing revenue.
