The leading email and SMS marketing platform for e-commerce — deep Shopify integration, AI-powered segmentation, flows and revenue attribution built for online stores
💰 Free up to 250 contacts · From $20/mo · 🆓 Yes — free plan · 👥 E-commerce brands and Shopify stores
Klaviyo is the leading email and SMS marketing platform for e-commerce — used by over 150,000 Shopify and WooCommerce stores to drive revenue through highly personalised, behaviour-triggered campaigns. Its deep integration with e-commerce platforms means Klaviyo knows what customers browse, add to cart, purchase and return — enabling automated flows like abandoned cart sequences, post-purchase follow-ups and win-back campaigns that consistently outperform generic email marketing. Klaviyo attributes over $3.7 billion in revenue to its platform annually.
Who is it for?
E-commerce businesses on Shopify, WooCommerce, BigCommerce and Magento who want to maximise revenue from their email and SMS marketing. Klaviyo is overkill for non-e-commerce businesses — general businesses are better served by ActiveCampaign or Mailchimp.

Klaviyo is the clear winner for Shopify stores — its native integration is deeper, its e-commerce flows are more sophisticated and its revenue attribution gives genuine insight into email ROI. Mailchimp is better for businesses with broader marketing needs beyond e-commerce email.
