Klaviyo

Email and SMS for ecommerce, now with a serious AI layer.

8.9/10Best ecommerce CRMUpdated September 12, 2026

The Aiacent take

Klaviyo is not 'an AI tool.' It is the ecommerce CRM that added AI in the places that matter: segments, subject lines, product recommendations, and (carefully) content. That is why it leads our ecommerce ranking. The brands making money on owned channels already live here; the AI features are leverage, not the reason the category exists.

If a vendor pitches you an 'AI email tool' for your store and they are not integrating with this customer graph, you are buying a sidequest.

Pros

  • Still the default marketing OS for serious ecommerce
  • AI helps with segments, content, and predictions — on top of a real platform
  • SMS, email, and reviews in one customer graph

Cons

  • Bills grow with your success, which feels like a tax
  • You can over-message if you turn every AI suggestion on
  • B2B / non-commerce CRM use is a stretch

Who it's for

  • DTC and ecommerce teams on Shopify, BigCommerce, and similar
  • Retention marketers who think in flows, not blasts

Who should skip it

  • B2B SaaS — use a product-led lifecycle tool
  • Stores that have not fixed their product catalog or tracking

What matters in the product

Flows and segmentation

The product. AI can suggest; your offer and cadence still decide whether you are a brand or an inbox pest.

AI content and predictions

Useful for variants and likely-to-buy audiences. Review everything that sounds like a person wrote it, because customers can tell.

Verdict

The ecommerce marketing platform to beat. Adopt its AI features after the flows are right, not instead of them.
