If you run a Shopify store, Klaviyo is the tool most of your peers are using — and for good reason. It treats ecommerce data as a first-class citizen: orders, products, carts, and browsing behavior flow in natively, and the pre-built flows (abandoned cart, browse abandonment, post-purchase, win-back) work on day one with revenue attribution baked in.
On the AI side, Klaviyo has invested heavily. K:AI spans generative content, Smart Send Time, predictive analytics, and conversational segment building, plus newer agentic features (a Marketing Agent that drafts ready-to-launch campaigns from your website, and a Customer Agent for support). Notably, the core AI features are available across plan tiers rather than locked behind an enterprise SKU.
The main trade-off is cost as you scale: contact-based pricing means the bill grows with your list, and SMS is billed separately. For brands where email is the primary revenue channel, most consider that a fair trade for the ecosystem and the out-of-the-box flows.
Strengths
