Klaviyo is worth the premium for Shopify stores doing $50K+/month where email drives significant revenue — the predictive analytics and revenue attribution justify 3-5x higher cost. Brevo is better for SMBs, service businesses, and budget-constrained stores that need email + transactional + SMS in one platform at 60-80% less than Klaviyo. Brevo's per-email billing model makes it dramatically cheaper for businesses with large lists and moderate sending frequency.

The Verdict
Choose Klaviyo if:
- Shopify store doing $50K+/month
- Email drives 20-40% of revenue
- You need predictive analytics and deep revenue attribution
- Willing to pay premium for ecommerce-specific features
Choose Brevo if:
- Budget is a primary concern
- You need email + transactional + SMS in one platform
- Service business, B2B, or early-stage ecommerce
- Large contact list with moderate sending frequency
- Need CRM included without extra cost
Choose Omnisend as middle ground:
- Ecommerce features at 40-60% less than Klaviyo
- More ecommerce-specific than Brevo
- Email + SMS + push in one platform
Practitioner note: The biggest cost trap with Klaviyo: storing unsubscribed profiles. Since Feb 2025, every profile counts toward billing. A 50K-profile Klaviyo account with 15K unsubscribed profiles pays $700/month when $500/month would cover the active profiles. On Brevo, those extra profiles cost nothing. Factor this into the comparison.
