Sendinblue (now known as Brevo) and Klaviyo pursue fundamentally different strategies — in pricing, automation, and e-commerce focus.
Klaviyo

Sendinblue / Brevo
Budget-friendly with EU data protection
Sendinblue stands out with a volume-based pricing model that pays off during seasonal swings. EU data centers, ISO certification, and a low entry barrier make it attractive for smaller teams.

Pricing: Scaling vs. simplicity
Klaviyo
Contact-based pricing: free up to 250 contacts and 500 emails, then roughly $150/month for 10,000 contacts. Suited for businesses with steady growth and a data-driven approach.
Sendinblue
Volume-based model: unlimited contacts, payment based on emails sent. Free plan: 300 emails/day. Paid plans from roughly $25/month for 10,000 emails — an advantage during seasonal swings.
Automation: Basic vs. high-end
Klaviyo
- Advanced flow builder with complex conditions
- Behavior-based segmentation and personalization
- AI predictions for the optimal purchase moment
- Multi-channel automation (email + SMS combined)
Sendinblue
- Visual drag-and-drop automation builder
- Basic flows (welcome series, cart abandonment, birthday emails)
- Limited complexity in conditional branching
Integrations: Breadth vs. depth
Klaviyo
300+ native integrations with deep real-time data sync for e-commerce platforms. Supports BI tools (Looker, Tableau, Segment), loyalty programs, and affiliate tracking — valuable for complex e-commerce operations.
Sendinblue
Around 60 integrations including Shopify, WooCommerce, Magento, WordPress, and Zapier with REST API. Sufficient for simpler setups, but less depth on e-commerce-specific data points.
Data protection: EU hosting vs. US storage
Klaviyo
US-based data storage, GDPR-compliant via the Trans-Atlantic Data Privacy Framework (TADPF) and standard contractual clauses (SCC). Sufficient for most DACH companies — but worth checking with strict data protection requirements.
Sendinblue
EU data centers in Paris, ISO-certified German data centers, full GDPR compliance without US data transfer. A clear advantage for DACH companies with strict data protection requirements.
