Klaviyo vs Brevo

Klaviyo and Brevo sit at opposite ends of the email marketing pricing spectrum. Klaviyo is the premium ecommerce platform — deep Shopify integration, predictive analytics, AI-powered product recommendations, and revenue attribution that shows exactly which emails drive sales. Brevo is the budget multi-channel platform — unlimited contacts, pay-per-email pricing, and bundled CRM, SMS, WhatsApp, and live chat. At 10,000 contacts, Klaviyo costs approximately $150/month; Brevo Business costs $18/month for 20,000 emails. That's an 8x price difference. Klaviyo justifies it for Shopify stores doing $500K+ where revenue attribution proves ROI. For smaller ecommerce stores or non-ecommerce businesses, Brevo delivers 70% of the functionality at 12% of the cost.

Our pick: Klaviyo (7.5/10 vs 7.3/10)

Klaviyo wins 2 out of 6 categories. Brevo is better for: small businesses that need email, crm, sms, and chat in one affordable platform — especially those with large contact lists but low send volume.

Pros & Cons

Klaviyo

Best-in-class ecommerce segmentation with nested conditions, real-time updates, and predicted metrics — no other ESP matches this for Shopify stores

Revenue attribution that shows clear ROI per campaign and per automation flow — users cite this as what justifies the premium price

Deepest Shopify integration available with real-time data sync, product feeds, and browse/cart abandonment triggers

Gets expensive fast: $150/mo at 10K contacts, $400/mo at 25K, $720/mo at 50K, $1,380/mo at 100K — significantly more than every competitor

February 2025 billing change: now charges for ALL active profiles including unengaged subscribers, spam signups, and abandoned checkout contacts. Widely viewed as a post-IPO revenue grab

Trustpilot rating of 2.1/5 — the worst of any tool we reviewed. Support is slow, no phone option, and declining post-IPO as they chase enterprise clients

Brevo

Pay-per-email pricing is unique and genuinely saves money — store unlimited contacts on every plan including free. A 50,000-contact list that only sends monthly newsletters costs a fraction of what Mailchimp or ActiveCampaign would charge

Most complete all-in-one at this price point: email, SMS, WhatsApp, CRM, transactional email, live chat, and landing pages. No competitor bundles this much under $20/month

Free plan includes unlimited contacts, 300 emails/day, CRM, and basic automation — one of the most generous free tiers available

Account suspensions without explanation are a recurring Trustpilot theme — users report being blocked for as few as 1 unsubscribe out of 488 recipients, told to 'go elsewhere' with no specific reason

Customer support is the #1 complaint across every review platform. Copy-paste responses, 16+ day resolution times, and contradictory information from different agents. Free users get zero support; Starter gets email only

October 2025 plan restructure pushed features up to higher tiers — landing pages and A/B testing now require the Standard plan ($18/mo), previously available on cheaper plans
