Auto-Follow-Up for Canceled Calendly Meetings with GPT-4, Loom & Asana

This n8n workflow automatically detects canceled meetings from Calendly, uses GPT to write a friendly follow-up message, and sends it via Gmail, complete with a personalized Loom video link. It also creates an Asana task to remind your team to follow up manually if needed.

Ideal for B2B consultants, agencies, and sales teams who want to salvage missed opportunities and stay top-of-mind with prospects after no-shows.

How it works / What it does A Calendly Webhook triggers the flow when a meeting is canceled. Edit Fields extracts the meeting details (who canceled, when, and why). A GPT-4 node writes a personalized follow-up email based on the meeting context. You manually paste in your Loom video link. A Merge node combines the AI-written message, user info, and video link. Gmail sends the follow-up message automatically to the contact. An Asana task is created for your team to track the missed call and optionally follow up manually.

How to customize the workflow

Update the GPT prompt to change the tone or add context based on your business. Replace Loom with a Vidyard, Tella, or custom-hosted video link. Add a Slack notification node to alert your sales team when a call is missed. Link with a CRM or Google Sheets to track follow-up activity across your pipeline.

This modular workflow helps you turn no-shows into new opportunities, while keeping your team organized and your leads engaged.
