Brevo
Brevo's Gmail inbox placement sits at just 72%, and June 2023 marked an all-time low of 67.7% overall deliverability per Encharge.io and emailtooltester tracking. Brevo auto-suspends accounts when complaint rates exceed 0.2% — Capterra reviewers report campaigns suspended even while maintaining 25-41% open rates. The free plan is capped at just 300 emails/day (too tight for most active lists), and Trustpilot complaints consistently describe 2-3 day support ticket delays with a meaningful share never getting a response at all.
Klaviyo
Klaviyo pricing scales roughly 20× from 500 to 25,000 contacts ($20/mo → ~$400/mo), and the February 2025 shift to 'active profile' billing means unsubscribed contacts still count toward your bill per sender.net analysis. There is no phone support — live chat routinely refers users to self-help docs, and one G2 reviewer documented emailing success@klaviyo.com 14 times with zero response while trying to scale up usage. A 25% price-increase cap applies to existing customers post-2025, and SMS costs are metered on top of the already-inflated Email+SMS plan tiers.
The Verdict
Choose Klaviyo if you're running an e-commerce store — the revenue attribution, predictive analytics, and Shopify-native flows justify the 3-4× cost difference once you're doing $10K+/mo in sales. Choose Brevo if you're a service or content business where e-commerce features don't apply; you'll pay one-quarter the cost and get better free-tier generosity, just monitor the 72% Gmail placement on every campaign.
