The Developer-First SendGrid Alternative

// Legacy SendGrid (@sendgrid/mail)
// Requires heavy npm dependency, async event webhooks to catch drops
import sgMail from '@sendgrid/mail';
sgMail.setApiKey(process.env.SENDGRID_API_KEY);

await sgMail.send({
  to: 'user@example.com',
  from: 'auth@yourdomain.com',
  subject: 'Your Login Code',
  html: '<p>Code: <strong>482910</strong></p>',
});
// ⚠️ Returns HTTP 202 Accepted even if silently suppressed

// Modern SadaSend (Zero Dependencies)
// Native fetch, low-latency dispatch, synchronous validation
const res = await fetch('https://api.sadasend.com/v1/emails', {
  method: 'POST',
  headers: {
    'Authorization': `Bearer ${process.env.SADASEND_API_KEY}`,
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    from: 'auth@yourdomain.com',
    to: 'user@example.com',
    subject: 'Your Login Code',
    html: '<p>Code: <strong>482910</strong></p>',
  }),
});

const data = await res.json();
// ✅ Instant message ID, pre-flight validation, and DLQ tracking
