Send an Email

// V0 generates this server action for your Next.js app
// Prompt: "add a contact form that sends email"

"use server";

export async function sendContactEmail(formData: FormData) {
  const response = await fetch("https://api.xmit.sh/email/send", {
    method: "POST",
    headers: {
      "Authorization": `Bearer ${process.env.TRANSMIT_API_KEY}`,
      "Content-Type": "application/json",
    },
    body: JSON.stringify({
      from: "Acme <hello@acme.com>",
      to: "team@acme.com",
      subject: "New Contact Form Submission",
      html: `<p>${formData.get("message")}</p>`,
    }),
  });

  return response.json();
}

Common Pitfalls

V0 generates client-side email calls

Ensure the generated code uses a Server Action or API route marked with 'use server' to keep API keys server-side.
