Platform Overview
Same power level — completely different audiences
ActiveCampaign and Klaviyo are both top-tier automation platforms. The difference isn't quality — it's who they were built for.
AC
ActiveCampaign
Email Automation + CRM for B2B & Services
ActiveCampaign is the deepest automation platform for businesses without a product catalogue — SaaS companies, agencies, consultants, and B2B teams. The CRM is integrated directly into the automation engine, conditional branching is available on all paid plans, and lead scoring drives sophisticated nurturing. No native Shopify sync — built for service and B2B journeys, not product catalogues.
KL
Klaviyo
Email & SMS Automation for E-commerce
Klaviyo was built exclusively for online stores — native Shopify and WooCommerce sync, per-flow revenue attribution, predictive CLV, browse abandonment, and SMS all included. Its automation is excellent for e-commerce flows but less flexible for complex B2B sequences. If you run a store, Klaviyo's data layer is in a different league from any competitor.
💡
Key insight: Both have excellent automation builders — the difference is the data model underneath. Klaviyo's data is product catalogues, purchase events, and cart values. ActiveCampaign's data is deals, lead scores, and CRM pipeline stages. Choose the platform whose data matches your business.

Automation Depth
Both are powerful — for different use cases
The builder quality is high on both platforms. The difference is the data layer underneath each one.
AC
ActiveCampaign — B2B Automation
The benchmark for complex conditional logic
ActiveCampaign's automation builder is the benchmark for B2B and services — unlimited conditional branches, CRM deal stage triggers, contact scoring that feeds back into automation logic, and goal-based automation that adjusts in real time. If your automation involves lead qualification, sales handoff, and multi-step B2B nurturing — nothing competes at this price point.
KL
Klaviyo — E-commerce Automation
Revenue engine for online stores
Klaviyo's flows are optimised around purchase behaviour — browse abandonment, cart abandonment, post-purchase sequences, and win-back flows, all triggered by real product and order data. Revenue attribution shows exactly what each flow earns. Slightly less flexible than ActiveCampaign for pure B2B sequence logic, but the e-commerce data layer makes every trigger more precise and measurable.
💡
Key difference: ActiveCampaign can connect to Shopify via Zapier and build abandoned cart sequences — but it has no native revenue attribution. If measuring email ROI per flow matters to your business, Klaviyo's native data layer is a significant advantage that's hard to replicate.
Pricing
ActiveCampaign is cheaper — Klaviyo has a free plan
Both use contact-based pricing. At comparable list sizes, ActiveCampaign tends to be 15–30% cheaper on email-only plans.

Email + SMSfrom €60/month
💡
The ROI argument: Klaviyo costs slightly more per contact — but revenue attribution lets you measure exactly what you get back. Stores typically attribute 15–30% of revenue to Klaviyo flows within the first 90 days. ActiveCampaign's value in B2B contexts is harder to quantify directly, but the CRM integration often replaces a separate CRM subscription, justifying the cost.

Final Verdict
The clearest platform split we've ever reviewed
If you sell products online — Klaviyo, no contest. The e-commerce data layer, revenue attribution, and native integrations make it the only serious choice for stores. If you're B2B, SaaS, or services — ActiveCampaign. The CRM integration, lead scoring, and automation depth for non-e-commerce journeys are unmatched at this price point.

FAQ
Common questions answered
The most common questions from people deciding between these two platforms.
Does ActiveCampaign work for e-commerce?+
Yes, but with important limitations. ActiveCampaign has e-commerce integrations via Zapier and a native WooCommerce plugin, and you can build abandoned cart sequences. The critical gap is revenue attribution — you can't see what each automation earns natively, and browse abandonment isn't possible without significant workarounds. For a store doing meaningful volume, Klaviyo's native data layer is an advantage that's hard to compensate for.
Does Klaviyo work for B2B or service businesses?+
Klaviyo can send emails to B2B contacts and run sequences, but it has no CRM, no deal pipeline, and no lead scoring — the features that make ActiveCampaign valuable for B2B are simply absent. If your process involves sales handoff, deal tracking, or complex lead qualification, you'd need a separate CRM alongside Klaviyo — eliminating the cost advantage.
Which is easier to set up?+
Klaviyo is faster to get started with for e-commerce — connect Shopify and your customer data is immediately available. Pre-built flow templates let you launch revenue-generating automations within hours. ActiveCampaign's power comes with more setup — especially the CRM, lead scoring, and complex automation sequences for B2B.
Does ActiveCampaign have SMS?+
Yes — ActiveCampaign offers SMS as an add-on, not as a native feature. It works, but it's less integrated than Klaviyo's SMS, where email and SMS flows share the same contact profile and can be triggered by the same e-commerce events. If SMS is a priority, Klaviyo's unified approach is cleaner for e-commerce use cases.
Which has better deliverability?+
Both maintain strong professional deliverability. Klaviyo's deliverability is particularly solid for e-commerce because its segmentation tools make it easy to suppress unengaged contacts. ActiveCampaign's deliverability is excellent for B2B with detailed engagement reporting. In practice, the difference is minimal when both platforms are used correctly.
