1. ConvertFlow
Best for: Higher-consideration ecommerce brands that want personalized popups and returning-subscriber messages inside a full, testable funnel.
Starting price: Free to install with powered-by links. Paid plans start at $29/mo for 10k monthly views, $99/mo for 30k views and CRM integrations, and $299/mo+ for 100k+ monthly views.
ConvertFlow personalizes popups, embedded forms and landing pages using visitor segments, Klaviyo data and answers collected in earlier quizzes, plus CRM data on the Pro plan. A popup can ask a question, branch into a quiz funnel that recommends products and bundles, and change what that shopper sees on later visits, including dedicated messages for returning subscribers. ConvertFlow AI drives agentic funnel experimentation across the full funnel, with automated A/B testing for landing pages, popups, quiz funnels and site content.
Strengths
- Personalization by segment, Klaviyo data and quiz answers, plus CRM data on Pro
- Returning-subscriber messages instead of repeat signup popups
- Multi-step popups that branch into quiz funnels with bundles
Limitations
- Full-funnel A/B testing is on the Pro plan (Personal and Prime include funnel variants)
- Full-funnel builds take more setup than a single popup; done-for-you help is available
- Pricing scales with monthly funnel views
