After a team is successfully registered in Supabase, Carnero.Dev dispatches a confirmation email via the Resend API. The email is sent from registro@carnero-dev.tech and includes the team’s full registration details rendered inside a styled HTML template. Email dispatch is a best-effort operation — a failure does not roll back the database record and the POST /api/register endpoint still returns 200 with email_sent: false.

​
Sending an Email

Once the Supabase insert succeeds, the handler resolves the RESEND_API_KEY from Astro’s import.meta.env with a process.env fallback. A new Resend instance is created per request, and resend.emails.send() is called with both the html and text fields. The return value is destructured to check mailResult.error; a non-null error is logged and reflected in the response body without aborting the 200 return. 
const resend = new Resend(resendApiKey);

const mailResult = await resend.emails.send({
  from: 'Carnero.Dev <registro@carnero-dev.tech>',
  to: repEmail,
  subject: 'Tu registro para Carnero.Dev fue confirmado',
  text: emailText,
  html: emailHtml
});

if (mailResult.error) {
  console.error('[RESEND_EMAIL_ERROR]', mailResult.error);
}

​
Email Content

The HTML template is a table-based layout optimized for Gmail, Outlook, Yahoo Mail, and mobile screens. It is composed of three main sections:
  • Header — Burgundy banner (#4a0e17) with the <Carnero.Dev/> logo in monospace type and the “Build The Future” tagline in gold (#d9a441), separated from the body by a gold bottom border.
  • Body — Personalized greeting addressing the representative by name, followed by a monospace data table with a left gold border containing five rows:
    • EQUIPO — team name
    • REPRESENTANTE — representative’s full name
    • CORREO — representative’s email address
    • INTEGRANTES — member count
    • CATEGORÍA — fixed value: Build The Future
    Below the table, a paragraph reminds recipients of the event date: “El hackathon comenzará el Viernes 16 de Octubre”, followed by a gold CTA button linking to https://carnero-dev.tech.
  • Footer — Dark panel (#050508) with the automated-message disclaimer and the sender attribution: “ITR Roque • Departamento de TICs”.

​
Plain Text Fallback

A text field is always included alongside html to improve deliverability and pass spam filters that penalize HTML-only messages. The plain text template mirrors the essential data from the HTML version: 
Hola ${repName},

Tu registro para Carnero.Dev fue confirmado exitosamente.

Equipo: ${teamName}
Representante: ${repName}
Integrantes: ${membersCount}

Nos vemos en el hackathon.
Build The Future.

​
Error Handling

Email dispatch has three distinct failure modes, all of which are handled without interrupting the successful registration response: 1. Missing or placeholder RESEND_API_KEY If import.meta.env.RESEND_API_KEY (and the process.env fallback) is either undefined or equals the literal string re_your_resend_api_key_placeholder, the server logs a warning and skips the entire Resend block: 
[RESEND_WARNING]: RESEND_API_KEY no configurado o mantiene valor por defecto. Saltando envío de correo.
The registration is still committed to Supabase. The 200 response body will contain email_sent: false and email_error: "Servicio de correo temporalmente desconectado.". 2. Resend API returns an error If resend.emails.send() resolves successfully but mailResult.error is non-null, the server logs the error object: 
[RESEND_EMAIL_ERROR] { ... }
The response body reflects this with email_sent: false and email_error set to mailResult.error.message. 3. Network or runtime exception If resend.emails.send() throws (network timeout, DNS failure, unexpected runtime error), the catch block logs the exception: 
[RESEND_EMAIL_EXCEPTION] { ... }
The caught error message is forwarded to email_error in the response. The registration remains saved in Supabase.
Email failures do not roll back the Supabase registration. Teams that report not receiving a confirmation email have still been registered — their data is in the database. Verify their record in the Supabase dashboard before asking them to re-submit the form.
Test email delivery locally by setting RESEND_API_KEY to a real Resend test key. Resend’s sandbox mode allows sending to your own verified email address without requiring a custom domain to be configured.
