What it does
How it works: This n8n workflow automates communication with meeting invitees to decrease no-show rates by sending timely email and WhatsApp reminders, and a clarification request if more information is needed to prepare the meeting. Step-by-step: The workflow is triggered by an incoming email notification from Calendly about a newly scheduled meeting. - It uses AI to extract key meeting data from the email content. - It checks if the invitee didn't provide sufficient information, and, if there is a need for more information, sends a clarification request email. - It calculates the waiting time required for the 24-hour and 1-hour reminders. - It uses an If node to determine the correct waiting path based on the meeting time. - It uses Wait nodes for timing the reminders correctly. - Finally, it sends a reminder email and a WhatsApp reminder before the meeting. Customization Options: - Replace Google Gemini with your preferred LLM model (though Gemini works on the free tier). - Tailor email and WhatsApp messages to speak your brand's language. - Replace Twillio node to WhatsApp node to be a completly free usage flow.
