Brevo vs Klaviyo: Best Email Tool for Ecommerce?

Klaviyo has dominated ecommerce email marketing for years. Its deep Shopify integration, revenue-focused analytics, and powerful behavioural segmentation made it the default choice for serious ecommerce brands. But Klaviyo's pricing has scaled dramatically as brands grow, and Brevo has built a compelling alternative that handles ecommerce use cases at a significantly lower cost. This comparison breaks down where each platform excels.

The Core Positioning

Klaviyo is purpose-built for ecommerce. Every feature — from its revenue dashboards to its pre-built Shopify flows — is designed with product-focused businesses in mind. It excels at connecting email behaviour to purchase data.

Brevo is a general-purpose marketing platform with strong ecommerce capabilities added through integrations and automation. It handles ecommerce workflows well, but without the same native depth as Klaviyo.

Pricing: Where Brevo Wins Decisively

Klaviyo's pricing is based on contact count and scales aggressively. As your list grows, your bill grows — even if you do not increase your sending frequency.

Klaviyo pricing examples:

• 0-500 contacts: $20/month (Email)
• 1,001-1,500 contacts: $45/month
• 5,001-10,000 contacts: $150/month
• 25,001-50,000 contacts: $400/month
• 100,000+ contacts: $700+/month

Brevo pricing:

• Free: 300 emails/day, unlimited contacts
• Starter: From $9/month, 5,000 emails
• Business: From $18/month, 20,000 emails

An ecommerce brand with 25,000 contacts pays $400/month with Klaviyo. The same brand on Brevo's Business plan, sending 20,000 emails/month, pays $18/month. Even at higher send volumes, Brevo's cost is a fraction of Klaviyo's.

Verdict on pricing: Brevo wins — the savings are substantial at any meaningful list size.

Shopify Integration

Klaviyo's Shopify integration is best-in-class. The native integration syncs product catalogues, order histories, cart data, customer lifetime value, and browsing behaviour in real time. Building a flow that triggers when a customer browses a specific product category or purchases from a specific collection is straightforward.

Brevo's Shopify integration (available through the Brevo Shopify app) syncs order data, customer information, and basic ecommerce events. Abandoned cart flows, post-purchase sequences, and product recommendation emails are all possible. The integration is reliable but not as deeply featured as Klaviyo's.

Winner: Klaviyo for depth of Shopify integration. Brevo works well but requires more setup for complex product-specific targeting.

Ecommerce Automation Flows

Both platforms support the core ecommerce automation flows:

• Abandoned cart recovery
• Post-purchase thank you + upsell
• Browse abandonment
• Win-back campaign for lapsed customers
• New customer welcome series
• VIP customer identification and rewards

Klaviyo's flow builder is optimised for ecommerce. Pre-built flow templates for Shopify are ready to use with minimal customisation. Conditional logic based on real-time purchase data (has bought product X, has not bought product Y) is seamless.

Brevo's automation builder handles all these flows but requires more manual setup for product-specific triggers. The automation interface is powerful but not ecommerce-first in its presentation.

Winner: Klaviyo for out-of-the-box ecommerce flow setup. Brevo for more flexible, lower-cost automation once configured.

Segmentation

Klaviyo's segmentation is among the most powerful in the industry for ecommerce. You can segment by: product purchased, category browsed, predicted lifetime value, predictive churn risk, purchase frequency, average order value, days since last purchase, and dozens more ecommerce-specific attributes. Predictive analytics (AI-driven churn prediction, LTV prediction) are included on paid plans.

Brevo's segmentation is based on contact attributes, list membership, and email engagement. For ecommerce-specific segmentation (product-level purchase history, AOV tiers), you need to pass this data to Brevo as custom contact attributes via the API or Shopify integration.

Winner: Klaviyo for native ecommerce segmentation depth. Brevo is capable but requires more data architecture work.

SMS Marketing

Klaviyo includes SMS marketing as part of its platform. SMS is tightly integrated with email flows — you can add an SMS step to any email automation sequence. Klaviyo's SMS pricing is additional (per message), but the unified inbox and shared contact database makes cross-channel marketing straightforward.

Brevo also includes SMS marketing, and it is more deeply integrated into its automation platform than Klaviyo's. SMS steps can be added to any email workflow. Brevo's SMS pricing is competitive on a per-message basis.

Winner: Tie. Both platforms handle email + SMS automation well.

Revenue and Analytics Reporting

Klaviyo's reporting is revenue-focused by design. Every dashboard leads with revenue attributed to email. You can see revenue per flow, revenue per campaign, predicted 90-day customer value, and year-over-year performance. If you run an ecommerce business, Klaviyo's analytics speak your language.

Brevo's reporting covers standard email metrics (open rate, click rate, bounce rate) plus basic conversion tracking via website script. Revenue attribution requires UTM parameters and external analytics. It is functional but not as immediately ecommerce-centric as Klaviyo's.

Winner: Klaviyo for revenue-first analytics. Brevo for standard email marketing metrics.

Customer Support

Klaviyo offers email support on all plans, with live chat on plans above $45/month. Response quality is generally high, though response times can be slow during peak periods.

Brevo offers email and phone support on paid plans, with live chat on Business plans. Phone support at lower plan tiers gives Brevo an edge for businesses that prefer direct human assistance.

Winner: Brevo for support accessibility.

Who Should Choose Brevo?

• Cost-conscious ecommerce brands that need professional email marketing without $400+/month bills
• Businesses with large contact lists where Klaviyo's pricing becomes prohibitive
• Non-ecommerce businesses that want a capable general-purpose platform
• Teams that need email + SMS + CRM in one affordable package
• Ecommerce brands that are comfortable configuring custom attributes for advanced segmentation

Who Should Choose Klaviyo?

• Shopify-first ecommerce brands where native product-level integration matters
• High-volume ecommerce businesses where revenue attribution reporting drives strategic decisions
• Brands that want predictive analytics (churn risk, LTV prediction) without custom development
• Teams that want ecommerce-specific flow templates ready to use with minimal setup
