Klaviyo is the dominant email platform for ecommerce brands, and the AI additions have made the gap between it and alternatives wider rather than narrower. The predictive analytics: which customers are likely to purchase again, who's at risk of churning, what someone's predicted lifetime value is: are trained on aggregated data across millions of Klaviyo accounts. That accuracy is hard to replicate in a smaller platform. The Marketing Agent for building flows and segments using natural language is genuinely useful for non-technical marketers.
Pricing is straightforward but scales with your contact count. The email plan starts at $20/month for 500 contacts and reaches $130/month at 10,000 contacts. Moving to Email + SMS adds roughly $15/month at the base tier. If you're serious about ecommerce email marketing and doing more than $500K/year in revenue, Klaviyo's feature depth is worth the price. For smaller operations, Omnisend covers the essentials at lower cost.
