LeadTrail

With LeadTrail, you are able to collect leads from multiple form plugins such as Elementor Forms, Contact Form 7, Gravity Forms, Ninja Forms, and WP Forms. As leads come in, you can group them, categorize them, assign qualities, and price them based on each of these. LeadTrail allows you to sell leads once or multiple times to registered buyers of your WordPress website.
