Klaviyo vs Brevo

Pros & Cons

Klaviyo

Market-leading 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 1.9/5 from 348 reviews — 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 actually 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
