Real Friction Points
Manually researched issues reported by actual users. Not AI-generated.
Klaviyo
Klaviyo's 2025 pricing restructure moved to active-profile-based billing, meaning your monthly cost scales automatically as your list grows — even inactive contacts who haven't opened an email in a year count as 'active profiles' unless suppressed. Trustpilot users report jumping from $39/month to over $200/month overnight. The free plan is tiny at 250 contacts/500 sends, and customer support response times are consistently slow, often taking hours per request.
Mailchimp
Mailchimp's e-commerce features are significantly weaker than Klaviyo's — no built-in product recommendations, limited Shopify integration depth (Mailchimp broke with Shopify for years), and basic segmentation compared to Klaviyo's behavioral e-commerce targeting. The free plan dropped to 250 contacts in January 2026 with automation removed. Reddit users report $45/month for 1,000 contacts with broken automation features.
The Verdict
Klaviyo is the clear winner for e-commerce stores, especially Shopify merchants — its deep product data integration, AI-powered recommendations, and multi-touch revenue attribution are leagues ahead of Mailchimp. However, Klaviyo costs 30-50% more at every tier. Choose Mailchimp only if you are not an e-commerce business or if budget is your primary constraint; for any serious online store, Klaviyo pays for itself in recovered revenue.
