Brevo vs Klaviyo: Best Choice for E-Commerce?

Klaviyo is considered the gold standard of e-commerce email marketing. Brevo is the versatile challenger that's growing rapidly in the e-commerce space. How do they actually compare — and which should you use for your online store?

The Fundamental Positioning Difference

Klaviyo was built specifically for e-commerce. Every feature is designed around purchase data, product recommendations, and revenue attribution. If you're on Shopify or WooCommerce, Klaviyo's native data integrations are deep and powerful.

Brevo is a broader marketing platform that includes solid e-commerce features (via its WooCommerce and Shopify integrations) alongside email, SMS, transactional email, and CRM. It's not purely e-commerce-focused, but it covers e-commerce use cases well.

Pricing: A Major Difference

Klaviyo pricing is contact-based and among the most expensive in the industry. At 10,000 contacts, you're looking at $150/month for email only. Add SMS and the cost increases further.

Brevo pricing is send-based with unlimited contacts. At comparable email volume, Brevo is typically 70–80% cheaper than Klaviyo for mid-sized lists.

For a store with 20,000 contacts sending weekly emails, Klaviyo might cost $250–400/month. Brevo would cost $40–80/month for the same volume.

Winner: Brevo — significantly cheaper at nearly every list size.

E-Commerce Data Integrations

Klaviyo's native Shopify integration is exceptionally deep. It syncs product data, purchase history, browsing behaviour, and customer lifetime value in real time. Out-of-the-box segments like "Predicted High Value Customers" and "Likely to Churn" are powered by Klaviyo's predictive analytics.

For Shopify merchants, Klaviyo has a genuine data advantage. The breadth of purchase-behaviour-based triggers available in Klaviyo automations is more extensive than Brevo's.

Brevo's WooCommerce and Shopify integrations provide purchase data, order history, and cart abandonment triggers — enough to build the core e-commerce automations (welcome, abandon cart, post-purchase, win-back). But Klaviyo's predictive analytics and product-level behavioural tracking are more advanced.

Winner: Klaviyo for Shopify stores that need deep product behavioural data.

Automation: Core E-Commerce Flows

For the standard set of e-commerce automations, both platforms deliver:

• Cart abandonment sequence
• Welcome series for new subscribers
• Post-purchase thank you and review request
• Browse abandonment (visited product page but didn't purchase)
• Win-back for lapsed customers
• VIP customer programme

Klaviyo's automations have more pre-built e-commerce templates and tighter product-level personalisation. Brevo can achieve the same outcomes but may require more manual setup.

Winner: Klaviyo on e-commerce automation templates and personalisation depth.

SMS Marketing

Both platforms offer SMS marketing. Brevo includes SMS as a native feature alongside email in the same workflow builder. Klaviyo's SMS is also natively integrated but is priced separately and can add significant cost for high-volume SMS senders.

Winner: Brevo for SMS cost efficiency.

Transactional Email

Klaviyo does not offer transactional email. Stores using Klaviyo typically need a separate service (like Postmark or Mailgun) for transactional emails, adding cost and complexity.

Brevo includes transactional email (SMTP + API) on all plans — no separate service required.

Winner: Brevo on transactional email.

Ease of Use

Klaviyo has a reputation for being powerful but complex. New users often find the interface dense, and advanced features have a learning curve.

Brevo is generally easier to navigate, especially for non-technical team members.

Winner: Brevo for accessibility.

Revenue Attribution Reporting

Klaviyo's reporting is built around revenue attribution — you can see exactly how much revenue each campaign and automation drove, and track ROI directly. This is one of Klaviyo's strongest features and is genuinely valuable for e-commerce decision-making.

Brevo provides campaign statistics (opens, clicks, revenue from integrations) but without the same depth of revenue attribution reporting.

Winner: Klaviyo on revenue reporting.

Who Should Choose Brevo for E-Commerce?

• WooCommerce stores looking for an affordable, all-in-one solution
• New or growing stores where Klaviyo's pricing is not yet justified
• Stores that need both email marketing and transactional email on one platform
• Multi-channel sellers who want email + SMS in one workflow

Who Should Choose Klaviyo for E-Commerce?

• Established Shopify merchants with large lists and high revenue where ROI justifies the cost
• Stores where predictive analytics and deep product behavioural segmentation are strategic priorities
• Businesses that want the most comprehensive e-commerce-specific automation templates out of the box
