Formidable Forms
Advanced WordPress form builder with data display — build pricing calculators and ROI tools as interactive lead capture.
The original WordPress contact form plugin — free, simple, and used on 5 million sites.
Contact Form 7 is the oldest and most installed WordPress form plugin, with over 5 million active installations. It provides a simple shortcode-based contact form with email notification support and basic CAPTCHA. Contact Form 7 is deliberately minimal — it handles the core mechanics of a contact form without additional features or a drag-and-drop builder. While it lacks the CRM integrations, conditional logic, and templates of modern form plugins, its simplicity and zero cost make it a viable choice for B2B sites that need a single basic contact form without any form management overhead. Extensions from third-party developers add CRM integrations, file uploads, and conditional logic.
Small B2B sites managed by solo founders or small teams with minimal technical overhead benefit from Contact Form 7's zero-cost simplicity. A basic contact form that delivers email notifications on submission is sufficient for B2B sites in the early stages, where CRM automation is not yet a priority. Its widespread use means virtually every WordPress developer and theme is compatible with it, reducing integration risk.
