ActiveCampaign vs Klaviyo: Which to Pick in 2026

It depends on list size and tier. On like-for-like entry email plans, ActiveCampaign is cheaper on smaller lists: at 1,000 contacts its Starter plan is about $15/mo billed annually, versus roughly $30/mo for Klaviyo's email plan (as of 2026, per vendor pricing and third-party comparisons). The gap narrows as lists grow — by around 10,000 contacts the two roughly converge (ActiveCampaign Starter ~$149/mo vs Klaviyo email ~$150/mo), and Klaviyo can undercut ActiveCampaign's higher Plus/Pro tiers at that size. Klaviyo bills on active profiles — every emailable contact, with email and SMS counted separately and no annual discount — so model your real profile count and SMS volume before deciding. Pricing is point-in-time.

Klaviyo, in most cases. It offers deep real-time bidirectional Shopify sync, predicted customer lifetime value, and per-message revenue attribution built specifically for e-commerce lifecycle marketing. ActiveCampaign connects to Shopify and WooCommerce too, but it is engineered around B2B automation and a sales CRM rather than store-level product and purchase data.

ActiveCampaign has a native sales CRM with pipelines, deal tracking, and lead scoring, available as a paid add-on on its higher plans (from roughly $68/mo as of 2026). Klaviyo does not offer a B2B sales CRM — it is an e-commerce customer-data platform focused on segmentation, flows, and revenue attribution, not deal management.

Yes. Some companies run Klaviyo for e-commerce lifecycle and ActiveCampaign for B2B or service pipelines, though needing both usually signals an undefined go-to-market motion. Migrating is straightforward via CSV export/import or native connectors; the effort scales with how many automations, flows, and segments you have to rebuild, not the contact count itself.
