Comment (by DvanKooten):

 @swissspidy The current code only uses the returned array values if they
 are actually set. Otherwise, it will use the passed arguments.

 {{{#!php
 if ( isset( $atts['to'] ) ) {
         $to = $atts['to'];
 }

 if ( isset( $atts['subject'] ) ) {
         $subject = $atts['subject'];
 }

 if ( isset( $atts['message'] ) ) {
         $message = $atts['message'];
 }

 if ( isset( $atts['headers'] ) ) {
         $headers = $atts['headers'];
 }

 if ( isset( $atts['attachments'] ) ) {
         $attachments = $atts['attachments'];
 }
 }}}

 So emails can be disabled by emptying the `to` or `message` field but that
 will still run the entire function, setting up the `PHPMailer` object etc.
