Technical Capabilities

MERU: Purpose-Built for Inbound

// Rich inbound processing capabilities
const address = await meru.addresses.create({
  userId: 'user_123',
  webhookUrl: 'https://your-app.com/webhook',
  ttlHours: 720
});

app.post('/webhook', (req, res) => {
  const event = meru.verifyWebhook(req.body, req.headers);
  
  const email = {
    subject: event.headers.subject,
    from: event.envelope.mailFrom,
    content: event.text || event.html,
    attachments: event.attachments, // Pre-processed
    spam: event.spam.score,
    authentication: event.authResults
  };
  
  processInboundEmail(email);
  res.json({ status: 'received' });
});

ZeptoMail: Limited Inbound Support

// Basic inbound capabilities (if available)
// Primarily designed for outbound transactional
app.post('/zepto-webhook', (req, res) => {
  // Limited inbound webhook support
  // Basic data structure
  // Manual processing required
  res.json({ status: 'ok' });
});
