What are Klaviyo forms?
Klaviyo's built-in signup forms: popups, flyouts, embeds, full-page forms and banners for growing email and SMS lists. They are a good fit for Klaviyo users who want simple, native list-growth forms at no extra cost.
Pricing: Included with Klaviyo (free plan up to 250 profiles; paid email plans from $20/mo).
Where ConvertFlow is different
ConvertFlow adds what Klaviyo forms don't: quiz funnels with product recommendations and bundles, personalized popups for returning subscribers, and full-funnel A/B testing, syncing every answer to Klaviyo profiles for email and SMS. ConvertFlow AI also drives agentic funnel experimentation across the full funnel, with automated A/B testing for landing pages, popups, quiz funnels and site content. Klaviyo is a ConvertFlow integration partner, and many brands use both together.
Which should you choose?
Klaviyo forms are the better fit for Klaviyo users who want simple, native list-growth forms at no extra cost. ConvertFlow is the better fit if you want quiz funnels, popups, landing pages and on-site personalization in one builder, synced to Klaviyo and other CRM integrations (Salesforce, HubSpot, Customer.io etc), with ConvertFlow AI running automated A/B tests across the full funnel.
