Final Verdict
Use ActiveCampaign if:
You're B2B or service-based and need deep CRM automation — lead scoring, deal stages, conditional branching based on CRM contact properties. ActiveCampaign's automation builder is unmatched for complex non-e-commerce sequences.
Use Klaviyo if:
You're DTC e-commerce and email directly drives purchase revenue. Klaviyo's vertically segmented infrastructure, Smart Sending, and e-commerce attribution make it the right tool for your use case.
ActiveCampaign wins on CRM automation depth for B2B; Klaviyo wins on e-commerce deliverability infrastructure. Both require the same external monitoring for Gmail reputation, Yahoo complaint data, inbox placement, and bot click filtering.
