설명
This plugin integrates with the Dilli Email Validation API (DEVA) to block fake or incorrectly formatted email addresses at form submission, ensuring higher-quality leads and significantly reducing spam.
This plugin requires an API Key which can be obtained for FREE by signing up here. Learn more about Dilli Email Validation API here.
This plugin hooks directly into the WordPress core email validation function (is_email()), which is used by most major form plugins. That means it works out of the box with popular form builders like:
- Contact Form 7
- WPForms
- Gravity Forms
- Ninja Forms
- Jetpack/Grunion contact forms
- WordPress registration forms
- and many others.
No need to modify your forms — just install and activate the plugin.
