1. ConvertFlow
Best for: Higher-AOV Shopify brands that want popups to be one part of a full, testable funnel feeding their email and SMS.
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 builds landing pages, popups, embedded and multi-step forms and quiz funnels in one no-code builder. Instead of sending email and SMS itself, it captures and segments subscribers for Klaviyo or other CRM integrations (Salesforce, HubSpot, Customer.io etc), recommends products and bundles through quiz funnels, and shows returning subscribers personalized offers instead of the same signup popup. ConvertFlow AI drives agentic funnel experimentation across the full funnel, with automated A/B testing for landing pages, popups, quiz funnels and site content.
