Migrate from SMTP / Nodemailer to Notify

Leave SMTP and Nodemailer transport for a single HTTPS send call.

SMTP is fine plumbing. For app email, an HTTPS API is usually simpler to deploy (no open ports, no SMTP credential sprawl, easier observability). Nodemailer can speak SMTP or other transports — Notify replaces the transport with one POST.

What changes

| | SMTP / Nodemailer | Notify | | --- | --- | --- | | Protocol | SMTP (often 587/465) | HTTPS JSON | | Auth | SMTP user/pass | x-api-key | | Body | html / text fields | message | | Ops | Relays, IP reputation DIY, firewall rules | Domain verify + API key |

Before / after

Nodemailer + SMTP

await transporter.sendMail({
  from: 'noreply@acme.com',
  to: 'user@example.com',
  subject: 'Welcome',
  html: '<h1>Welcome</h1>'
});

Notify

await fetch('https://notify.cx/api/email/send', {
  method: 'POST',
  headers: {
    'x-api-key': process.env.NOTIFY_API_KEY!,
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    from: 'noreply@acme.com',
    to: 'user@example.com',
    subject: 'Welcome',
    message: '<h1>Welcome</h1>'
  })
});

Migration checklist

  1. Add NOTIFY_API_KEY and remove SMTP secrets from app config where possible
  2. Verify your domain in Notify
  3. Swap sendMail helpers for a small sendEmail() wrapper around Notify
  4. Use logs instead of scraping SMTP transcripts
  5. Add webhooks on Pro/Scale for bounces
