Reduce meeting no-shows with Gemini and WhatsApp

Started by an arriving email, and works across Email and Twilio. It hands the judgement calls to Gemini. 14 steps, 2 branches, 3 loops or waits: a working afternoon to understand properly.

Questions

What does it need to run?

An n8n account, plus your own Email and Twilio accounts, and a key for Gemini. You connect your own accounts after importing it; none are included.

What starts it?

It starts on an arriving email.

Does it use AI?

Yes. It calls Gemini. Model calls are billed by the provider, not by n8n.

How long does it take to set up?

Plan an afternoon. 14 steps is enough that you should read each one before running it.

How do I import it?

Copy the workflow, open a new workflow in n8n and paste. The steps appear on the canvas, ready for your own accounts.

Before you run it

Nothing here has been tested by us. It is somebody's working automation, read and described from its own steps. Treat the connections it wants as a list of accounts it will touch, and read the 14 steps before you point it at anything that matters.
