Use Klaviyo for ecommerce (Shopify/WooCommerce stores where email drives revenue). Use ActiveCampaign for B2B (lead nurture, sales automation, CRM integration). They're built for different use cases. Klaviyo has deeper ecommerce features (revenue attribution, predicted CLV, purchase-based flows). ActiveCampaign has a more powerful general automation builder and costs less at equivalent list sizes. Don't use Klaviyo for B2B. Don't use ActiveCampaign for serious ecommerce.
Klaviyo vs ActiveCampaign: Ecommerce vs B2B Automation (2026)
Built for Different Jobs
This isn't a "which is better" comparison — it's a "which is right for your use case" decision.
Klaviyo = ecommerce email + SMS platform. Every feature optimizes online store revenue.
ActiveCampaign = marketing automation + CRM platform. Every feature optimizes lead nurture and sales processes.
Using Klaviyo for B2B is like using a Ferrari for grocery runs. Using ActiveCampaign for ecommerce is like using a minivan for racing. Both drive. Neither is optimal for the wrong purpose.
Pricing (March 2026)
| Contacts | Klaviyo (Email) | ActiveCampaign (Plus) |

| 10,000 | $150/mo | $99/mo |
| 25,000 | $400/mo | $186/mo |
| 50,000 | $700/mo | $339/mo |
ActiveCampaign is cheaper at 5K+ contacts. Klaviyo's pricing premium is justified if ecommerce-specific features drive measurable revenue.

The Verdict
| Your Business | Use |
|---|---|
| Shopify store, email drives 20%+ revenue | Klaviyo |
| Shopify store, tight budget | Omnisend (Klaviyo alternative) |
| B2B company, lead nurture focus | ActiveCampaign |
| B2B company, need full CRM | HubSpot |
| Agency managing B2B clients | ActiveCampaign |
| Agency managing ecommerce clients | Klaviyo per client |
| Service business with simple needs | ActiveCampaign or MailerLite |
Practitioner note: When a client says "I need Klaviyo" and they're a B2B SaaS company, I redirect them to ActiveCampaign. When they say "I need ActiveCampaign" and they run a Shopify store doing $200K/month, I redirect them to Klaviyo. Matching the platform to the business model matters more than any individual feature.
Practitioner note: Both platforms changed their billing in 2025 to charge for all contacts (including unsubscribed). On both, clean your list monthly. Read our full Klaviyo review and ActiveCampaign review for in-depth analysis of each platform. The billing change makes list hygiene a direct cost management tool, not just a deliverability practice.

Frequently Asked Questions
Which is cheaper?
ActiveCampaign at every tier. At 5K contacts: ActiveCampaign Plus $49/mo vs Klaviyo $100/mo. At 25K: ActiveCampaign $186/mo vs Klaviyo $400/mo. The gap widens with list size. But Klaviyo's ecommerce ROI often justifies the premium for stores where email drives significant revenue.
Can I use ActiveCampaign for ecommerce?
For basic ecommerce email: yes. ActiveCampaign has Shopify and WooCommerce integrations. For serious ecommerce with revenue attribution, predicted CLV, and advanced product-based segmentation: Klaviyo is significantly better. ActiveCampaign's ecommerce features are adequate but not deep.
Can I use Klaviyo for B2B?
Technically yes, but Klaviyo is built for ecommerce. It lacks CRM pipeline features, lead scoring comparable to ActiveCampaign, and B2B-specific automation triggers. For B2B, you'd be paying a premium for ecommerce features you'll never use.
Which has better automation?
Depends on type. Klaviyo has better ecommerce-specific automation (abandoned cart, product recommendations, purchase-based flows). ActiveCampaign has a more powerful general-purpose automation builder with complex branching, CRM triggers, and lead scoring. For non-ecommerce automation, ActiveCampaign wins.
Which has better deliverability?
Comparable. Both support custom domain authentication, both maintain shared IP pools, both offer engagement-based features. Klaviyo's Smart Sending and ActiveCampaign's engagement management both improve deliverability. Choose based on use case, not deliverability.
