Klaviyo
Email and SMS platform for e-commerce that automates customer retention with AI
Overview
Klaviyo is the reference for marketing automation in e-commerce. The platform unifies email, SMS, and mobile push in one tool, with ultra-precise behavioral segments based on purchase, browsing, and cart data. AI generates customer lifetime value predictions, optimal send times, and content suggestions.
Klaviyo's strength lies in its native connection to Shopify data: every cart abandonment, purchase, and visit is automatically actionable. The free plan covers up to 250 contacts with 500 emails/month, letting you test seriously before moving to paid.
Our verdict
Klaviyo is the #1 choice for a Shopify merchant that wants data-driven growth. Be aware: costs rise quickly as your contact base grows (billing by active profiles since 2025), and the learning curve for advanced automation takes a few weeks. Avoid if your list is under 500 contacts and you don't have email sequences to automate: Shopify Email will suffice.
