Steps

  1. Enable Event Webhook with a public HTTPS URL
  2. Turn on Signed Event Webhook; verify the ECDSA signature (X-Twilio-Email-Event-Webhook-Signature + Timestamp headers) with the public key
  3. Events arrive as a JSON array — process each element (delivered, open, bounce, dropped...)
  4. Return 2xx fast; SendGrid retries with backoff for ~24h on failure
