You can add following code in your theme’s (child theme’s if you are using) functions.php

add_filter( 'fep_filter_message_before_send', function( $message ) {
	// The @ symbol must be surrounded by character on both sides
	$message['message_content'] = preg_replace( '/[^@\s]*@[^@\s]*\.[^@\s]*/', '[EMAIL]', $message['message_content'] ); # for emails
	
	// Take any string that contains only numbers, spaces and dashes,
	// Can optionally have a + before it.
	$message['message_content'] = preg_replace( '/\+?[0-9\-]{5,}/', '[PHONE]', $message['message_content'] ); # for phone numbers
	
	return $message;
});

It will work most of the time.
