Review and reply to business emails with Gmail and OpenAI

Started by an arriving email, and works across Email, Gmail, Google Drive and Qdrant. It puts DeepSeek and OpenAI behind a retrieval step, so answers are drawn from documents you supply rather than from the model alone. 22 steps: large, and worth reading before you trust it with anything live.

Questions

What does it need to run?

An n8n account, plus your own Email, Gmail, Google Drive and Qdrant accounts, and a key for DeepSeek and OpenAI. 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 DeepSeek and OpenAI. Its answers draw on documents you give it, not on the model alone. Model calls are billed by the provider, not by n8n.

How long does it take to set up?

Take your time. At 22 steps it is large: read it before trusting it with anything live.

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 22 steps before you point it at anything that matters.
