function email_post_type() {
	$labels = array(
		'name'                  => _x( 'Emails', 'Post Type General Name', 'redpishi_com' ),
		'singular_name'         => _x( 'Email', 'Post Type Singular Name', 'redpishi_com' ),
		'menu_name'             => __( 'Emails', 'redpishi_com' ),
		'name_admin_bar'        => __( 'Email', 'redpishi_com' ),
		'search_items'          => __( 'Search Emails', 'redpishi_com' ),
	);
	$args = array(
		'label'                 => __( 'Email', 'redpishi_com' ),
		'description'           => __( 'Email information page.', 'redpishi_com' ),
		'labels'                => $labels,
		'supports'              => array( 'title', 'editor'),		
		'public'                => false,
		'show_ui'               => true,
		'show_in_menu'          => true,
		'menu_position'         => 5,
		'menu_icon'             => 'dashicons-email-alt2',
		'show_in_admin_bar'     => false,
		'exclude_from_search'   => true,
		'publicly_queryable'    => false,
		'map_meta_cap'     	    => true,
		'capability_type'       => 'page',
		'capabilities' 			=> ['create_posts'       => false,],	
	);
	register_post_type( 'email', $args );
}
add_action( 'init', 'email_post_type', 0 );





/*
 * Save emails that failed to send 
 * */
add_action( 'wp_mail_failed', function ( $wp_error ) {
	$subject = $wp_error->error_data["wp_mail_failed"]["subject"] .' - Failed';
	$message = $wp_error->error_data["wp_mail_failed"]["message"];	
	$post_data = array(
		'post_title' => $subject,
		'post_content' => $message,	
		'post_status' => 'publish',
		'post_type'	 => 'email',
	);
	$post_id = wp_insert_post( $post_data );
} , 10, 1 );  



/*
 * Save emails that have been sent successfully
 * */
add_action( 'wp_mail_succeeded', function ( $mail_data ) {
	$subject = $mail_data["subject"] .' - Succeeded';
	$message = $mail_data["message"];
	$post_data = array(
		'post_title' => $subject,
		'post_content' => $message,	
		'post_status' => 'publish',
		'post_type'	 => 'email',
	);
	$post_id = wp_insert_post( $post_data );
} );

After activating the above code, an additional option of “Email” will be added to the WordPress dashboard, and from now on, all sent emails will be visible there.

Next to the title of emails that have been successfully sent, the word “Succeeded” is written. And next to the title of emails that have failed to be sent, the word “Failed” is written.

If you don’t want the successfully sent emails to be stored in the database, you can find the following section in the code and delete it:

/*
 * Save emails that have been sent successfully
 * */
add_action( 'wp_mail_succeeded', function ( $mail_data ) {
	$subject = $mail_data["subject"] .' - Succeeded';
	$message = $mail_data["message"];
	$post_data = array(
		'post_title' => $subject,
		'post_content' => $message,	
		'post_status' => 'publish',
		'post_type'	 => 'email',
	);
	$post_id = wp_insert_post( $post_data );
} );
