Contact forms can negatively affect the INP (Interaction to Next Paint) metric if their scripts are loaded on every page of the site. To follow this, it is recommended to disable the global loading of the plugin's resources.
To disable the loading of scripts and styles on all pages except the contact page, add the following code to the functions.php file of your theme:
// Disable global loading of Contact Form 7 JS and CSS
add_filter( 'wpcf7_load_js', '__return_false' );
add_filter( 'wpcf7_load_css', '__return_false' );
// Conditional loading only on the contact page (upload 'contacts' with your slug)
add_action( 'wp_enqueue_scripts', 'custom_load_cf7_assets' );
function custom_load_cf7_assets() {
if ( is_page( 'contacts' ) ) {
if ( function_exists( 'wpcf7_enqueue_scripts' ) ) {
wpcf7_enqueue_scripts();
}

wpcf7_enqueue_styles();
}
}
}

Typical problems and how to reflect them
Emails do not reach the recipient
The most large reason is the use of the standard PHP mail function, which is blocked by many hosting providers. Solution: configure SMTP authentication via the Postman plugin or a similar service.
The form constantly flags messages as spam
Check your Akismet settings and utilize that the form contains mandatory name and email fields. It is also recommended to add a honeypot field via third-party add-ons.
404 Not Found error upon submission
This error occurs due to a permalink conflict. Solution: go to Settings, then Permalinks, and simply click the Save Changes button to update the .htaccess file structure.
