Klaviyo AI

Klaviyo is the email and SMS platform most Shopify brands run on. The AI layer adds three useful features.

Predictive Sending learns each subscriber's best open time and delivers their email at that individual moment, instead of blasting at a fixed schedule. AI Subject Lines suggests variants for your sends and predicts open rates for each. AI Segments builds audience filters from plain English (something like "customers who bought in 30 days but haven't opened our last 3 emails").

The integration with Shopify is the closest of any ESP. Customer data, order history, browsing behavior, and abandon-cart events sync automatically and trigger flows in Klaviyo without any setup work. Predictive features typically lift open rates 5-15 percent over scheduled sends.

Tiered subscription priced by contact count, with email and SMS included in most plans. AI features are bundled into the standard pricing rather than charged separately.

Best for ecommerce brands running email and SMS at scale on Shopify. For non-ecommerce marketing automation, alternatives like HubSpot offer broader functionality across other industries.
