Use case overview

An n8n workflow pulls the day's Google Calendar appointments, places automated voice calls via Retell AI, then sends follow-up SMS through Twilio.

Reported experience

  1. What they did

    The author built an n8n workflow that runs on a schedule each morning. It reads that day's appointments from Google Calendar and has Retell AI place an automated voice call to each customer as a reminder. After a short delay it sends a personalized follow-up text through Twilio. The post describes no manual steps once the workflow is running.

  2. How it went

    The post claims the workflow saves time and keeps reminders consistent without human involvement. It gives no numbers, no results from real use, and no account of failures.

  3. Worth knowing

    The post is a brief overview with a screenshot. It gives no setup details, such as the call script, the delay length, or how phone numbers are pulled from calendar events.
