Email Webhook to Phone Call: Instant Voice Alerts from Email Events
🔑 Key Takeaways:

Webhooks provide real-time notifications when emails arrive or are sent. An email webhook to phone call integration turns those events into instant voice alerts—perfect for monitoring systems, security incidents, or urgent escalations. Robotalker builds these custom webhook handlers to connect email events with telephony engines and legacy databases for fast, reliable response.
