CallPaywall Web is a WordPress plugin that integrates with Contact Form 7 to screen all form submissions server-side. Real customers are delivered free, sales pitches are held until the sender pays to reach the inbox, and spam is silently dropped. The service requires a CallPaywall account and operates with a fail-open design to ensure legitimate messages are never blocked by outages.
In the Forms, surveys & polls space, CallPaywall Web takes a focused approach. It focuses on receiving too many sales pitches and spam through contact forms while still allowing genuine customer inquiries. It is built as a B2B product for website owners using Contact Form 7. CallPaywall Web follows a freemium model. CallPaywall Web is available on the web, and it can be self-hosted.
Behind CallPaywall Web is callpaywall1, and the product first shipped in 2026. Key capabilities include Form Screening, pay-to-Send, and Spam Filtering. It exposes integrations via a public API.
