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

MailerLite

89.8% deliverability rate across 5 independent test rounds (EmailToolTester) — highest we found among all platforms tested

Comfort starts at $12/month and Power starts at $25/month

Won 'Best Email Marketing Tool for Ease of Use' every year from 2023-2026 across G2 and Capterra

Account approval/termination is a real problem — 60% of Capterra reviews mentioning it were negative. Users report accounts terminated without warning and no refund

Free is limited to 250 subscribers and 2,500 monthly emails as of June 16, 2026

Limited analytics — no heatmaps, no custom reports, no revenue attribution, no bot-click filtering. If data matters to you, this will frustrate you
