Call and text appointment reminders every morning
An n8n workflow pulls the day's Google Calendar appointments, places automated voice calls via Retell AI, then sends follow-up SMS through Twilio.
Done with n8n
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.
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.
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.
Try it yourself with n8n
Build an n8n workflow that runs every morning at [time], pulls today's appointments from my Google Calendar [calendar name], calls each client with a Retell AI voice agent to confirm, and then texts a follow-up through Twilio. Use this script: [reminder wording]. Before the first live run, pause and show me the full list of people it will call and text, and test it only on my own number first.
