Das Template wird zuerst gerendert und dann dem htmlBody übergeben
public function sendOfflineAlert(string $mail, string $subject, string $fallback, $order)
{
Craft::$app->getView()->setTemplateMode(View::TEMPLATE_MODE_SITE);
$html = Craft::$app->getView()->renderTemplate('_emails/offlinePaymentAlert.twig', [ 'order' => $order]);
$mailer = Craft::$app->getMailer();
$mailer->htmlLayout = false;
$mailer->textLayout = false;
$mailer->compose()
->setTo($mail)
->setSubject($subject)
->setHtmlBody($html)
->send();
}
