Reduce spam, fix typos, and capture quality leads. == Description == Stop fake or mistyped email addresses from slipping through your website forms. By integrating the powerful Dilli Email Validation API (DEVA), this plugin ensures only valid, correctly formatted email addresses are accepted—helping you capture real leads and eliminate spam. This plugin requires an API Key which can be obtained for FREE by [signing up here](https://deva.dillilabs.com/register). Learn more about Dilli Email Validation API [here](https://www.dillilabs.com/products/email-validation-api/). 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. = Features = * Validates email address format. Ex: email address `fooAtdillilabs.com` is invalid because of missing '@' * Checks for existence of MX records of the email address domain.
