Send an Email

// Lovable generates backend functions for your app
// Request email functionality in the chat

export async function sendInvoiceEmail(
  to: string,
  invoiceId: string,
  amount: number
) {
  const response = await fetch("https://api.xmit.sh/email/send", {
    method: "POST",
    headers: {
      "Authorization": `Bearer ${process.env.TRANSMIT_API_KEY}`,
      "Content-Type": "application/json",
    },
    body: JSON.stringify({
      from: "Acme <billing@acme.com>",
      to,
      subject: `Invoice #${invoiceId}`,
      html: `<p>Invoice #${invoiceId} for $${amount} is ready.</p>`,
    }),
  });

  return response.json();
}

Common Pitfalls

Lovable places API logic outside the server boundary

Verify that email functions are in a server-only module or edge function, not exposed to the client bundle.

Is there a rate limit for Lovable integration?

Transmit offers high-throughput sending with dynamic scaling. Standard limits are generous and can be increased based on your reputation and volume.
