Manual Integration

For forms not automatically detected, add the data-rv-email attribute to any email input field:

<input type="email" 
       name="email" 
       data-rv-email 
       placeholder="Enter your email" />

The plugin will automatically find inputs with this attribute and apply real-time verification.
