Klaviyo

If you run an e-commerce store on Shopify or WooCommerce, Klaviyo's native purchase data integration, revenue attribution, and SMS channel make it the strongest email platform — no other tool connects email behavior to actual store revenue as precisely.

What it does well
  • Native Shopify/WooCommerce sync brings purchase data, browse history, and CLV predictions into segments automatically
  • Email and SMS in a single platform — one dashboard, unified subscriber profile, no extra tool needed
  • Revenue attribution per campaign and per flow — you can see exactly how much each email earned
Watch out for
  • Free tier is tiny: 250 profiles and 500 emails/mo — you'll hit the paywall quickly if you have any traction
  • Not designed for B2B — there's no CRM pipeline, lead scoring, or sales-stage logic

Frequently Asked Questions

Should I use Klaviyo or ActiveCampaign for my Shopify store? +

Klaviyo — unambiguously. Its native Shopify data model means you can segment by lifetime value, purchase frequency, and product categories without manual syncing. ActiveCampaign requires a third-party connector and doesn't surface store revenue data as natively. For Shopify, Klaviyo is the standard.

Does Klaviyo work for B2B email marketing? +

Klaviyo can technically be used for B2B, but it lacks the CRM pipeline, lead scoring, and multi-step sales-cycle automations that B2B teams need. ActiveCampaign is purpose-built for B2B and will give you significantly better tools for nurturing leads through a longer sales process.

Which platform has better SMS marketing: Klaviyo or ActiveCampaign? +

Klaviyo — it has native SMS built into the same platform with unified subscriber profiles, so you can trigger SMS follow-ups based on email opens or cart abandonment seamlessly. ActiveCampaign requires a Twilio or Postscript integration to send SMS, which adds setup complexity and cost.
