Klaviyo

Klaviyo is purpose-built for online stores. It combines email and SMS marketing automation with native connectors to Shopify, WooCommerce, and other cart platforms, so customer behavior syncs automatically. The platform tracks revenue attributed to each campaign, letting you see exactly which emails drove sales.

Automated flows handle cart abandonment, post-purchase follow-ups, and win-back sequences. If you sell online and need marketing that ties directly to your store's transactions, Klaviyo removes the friction of manual data imports.
