The Bottom Line
For e-commerce businesses, Klaviyo is the clear market leader. Its native understanding of e-commerce data, combined with powerful segmentation and automation, translates directly to revenue growth.

Alternatives to Klaviyo
Frequently Asked Questions
No, Klaviyo works with many e-commerce platforms including WooCommerce, BigCommerce, Magento, and custom stores via API. However, Shopify is its strongest integration as a Shopify Plus preferred partner. The platform syncs real-time data from any supported store, including products, orders, browsing behavior, and customer profiles. Non-e-commerce businesses can use Klaviyo, but they won't benefit from its strongest features.
Klaviyo is typically 2-3x more expensive than Mailchimp at the same contact count. For example, 10,000 contacts costs approximately $150/month on Klaviyo vs $100/month on Mailchimp. However, Klaviyo includes full features on all plans, advanced e-commerce segmentation, and SMS marketing, whereas Mailchimp charges extra for advanced features. For e-commerce businesses, Klaviyo's higher ROI through better automation and personalization often justifies the price difference.
Flows are Klaviyo's automated email and SMS sequences triggered by customer actions. Popular flows include abandoned cart reminders (triggered when items are left in cart), welcome series (triggered by email signup), post-purchase follow-ups (triggered by order completion), browse abandonment (triggered by product viewing without purchase), and win-back campaigns (triggered by inactivity). Klaviyo offers 61+ pre-built flow templates that can be activated with a few clicks.
