+import { getMailer } from '@kit/mailers';
+import { renderAccountDeleteEmail } from '@kit/email-templates';
+
+async function sendSimpleEmail() {
+    // Get mailer instance
+  const mailer = await getMailer();
+
+  // Send simple email
+  await mailer.sendEmail({
+    to: 'user@example.com',
+    from: 'noreply@yourdomain.com', 
+    subject: 'Welcome!',
+    html: '<h1>Welcome!</h1><p>Thank you for joining us.</p>',
+  });
+}
+
+async function sendComplexEmail() {
+  // Send with email template
+  const { html, subject } = await renderAccountDeleteEmail({
+    userDisplayName: user.name,
+    productName: 'My SaaS App',
+  });
+
+  await mailer.sendEmail({
+    to: user.email,
+    from: 'noreply@yourdomain.com',
+    subject,
+    html,
+  });
