Klaviyo vs Brevo: Which Is Better for Shopify Stores?

Klaviyo and Brevo solve the same job, marketing email for a Shopify store, in two very different ways. Klaviyo is the premium, ecommerce-native power tool with the deepest Shopify data sync and segmentation in its class. Brevo is the cheapest all-in-one option, and it bills in a fundamentally different way: by how many emails you send, not how many contacts you store.

This comparison is grounded in current pricing and feature research as of June 2026. Pricing scales differently on each tool, so treat the numbers as a guide and confirm live rates before you commit.

Quick verdict

Choose Klaviyo if email is a serious revenue channel, you need surgical segmentation and per-flow revenue attribution tied to actual Shopify orders, and you have a marketer or agency to set it up. The depth and the learning curve are worth it when email drives real money.

Choose Brevo if you want the cheapest all-in-one (email, SMS, WhatsApp, transactional, and a basic CRM in one bill), and especially if you have a large list that you mail infrequently. Because Brevo bills on email volume rather than contacts, a big-but-quiet list can cost far less here than anywhere else.

Quick comparison

All pricing above is indicative and as of June 2026.

The pricing-model difference (this is the whole story)

The single most important thing to understand is how each tool charges you.

• Klaviyo bills on active profiles. Your cost is driven by how many contacts you store, and since February 2025 that includes all active profiles, anyone with an email that could be mailed, including checkout-abandon contacts who never opted in. As your list grows, your bill grows, even if you only send one campaign a month. Klaviyo's Email plan starts around $20/month for 251 to 500 profiles and scales to roughly $100/month at 5,000 and $150/month at 10,000.
• Brevo bills on email volume. Contact storage is effectively unlimited (up to 100,000 stored on the free plan), and you pay for how many emails you send. The Starter plan begins around $9/month for about 5,000 emails and scales to roughly $69/month for 100,000 emails; the Standard plan starts around $18/month and adds automation, A/B testing, and removes Brevo branding.

The practical takeaway: if you have a large list that you mail often, Klaviyo's per-contact model and Brevo's per-email model can land in similar territory. But if you have a large list that you mail infrequently (say 50,000 contacts and two campaigns a month), Brevo is dramatically cheaper because you are not paying to store contacts you rarely touch.

Features

Klaviyo wins decisively on ecommerce depth. Predicted CLV, churn risk, and next-order date sit on every profile, and revenue is tracked at the individual flow level, which makes ROI defensible flow by flow. Brevo wins on breadth for a small team: transactional email, SMS, WhatsApp, and a basic CRM all live under one subscription, which can replace two or three separate tools.

Shopify integration depth

Both install from the Shopify App Store, but the depth differs.

Klaviyo has the deepest Shopify integration of any mid-market email tool: real-time, bidirectional sync of orders, products, cart events, fulfillments, and refunds, plus 350+ integrations and a very large agency ecosystem. That ecosystem matters in practice, because hiring help or switching agencies later is straightforward.

Brevo's integration (available through its Shopify app) is functional but shallower. It syncs customer data, purchase history, and order status, and supports Shopify triggers for abandoned cart, post-purchase, and browse abandonment. Its ecommerce dashboard shows aggregate revenue and retention data but does not match Klaviyo's per-flow, per-campaign attribution granularity.

Who each is for

Klaviyo is for Shopify and DTC stores doing meaningful revenue (a commonly cited benchmark is around $50K+/month GMV) that need precise segmentation and per-flow attribution, and that have a dedicated email marketer or an agency.

Brevo is for budget-conscious stores that want an affordable all-in-one (email, SMS, transactional, and CRM in one place), stores operating across multiple markets that want WhatsApp and multi-language messaging, and especially brands with large lists and moderate send frequency where the email-volume pricing wins outright.

Pros and cons

Klaviyo pros: best-in-class ecommerce segmentation; defensible per-flow revenue tracking; huge ecosystem and talent pool. Klaviyo cons: expensive at scale, and the all-active-profiles billing can inflate costs if list hygiene is poor; steep learning curve; SMS is a separate add-on.

Brevo pros: uniquely cheap for large lists with moderate send frequency; true all-in-one including transactional email and a built-in CRM; beginner-friendly editor and workflow builder. Brevo cons: shallow ecommerce segmentation versus Klaviyo; limited template variety and a basic landing-page builder; some users have reported account-suspension issues tied to list-hygiene enforcement, a risk worth weighing if your revenue depends on email.

Final recommendation

If email is a core revenue channel, you are scaling, and segmentation precision plus per-flow attribution are non-negotiable, Klaviyo earns its price. Visit Klaviyo to get started.

If you want the cheapest credible all-in-one, you mail a large list infrequently, or you want transactional email and a basic CRM bundled in, Brevo is the smarter pick on cost. Visit Brevo to try the free plan.
