Ugly whitespace at the end of message

Hi,

I am using a HTML E-Mail template and also your plugin. Unfortunally, the tracking image adds an ugly vertical whitespace before the mail footer appears. Is it possible to add “display:none” to the following function without breaking things? I realized that the mail looks totally fine after adding the display:none property and mail open logs still seem to work fine…

public function get_track_code( $email_id ) {

return “<img style=’display:none;’ src=\”” . esc_url( get_home_url() . $this->rw_url_email_open . $email_id . ‘/track-log’ ) . “\” alt=\”track\” />”;

}
