Good to know

At time of writing, each Gemini request is billed per token. See [Gemini Pricing](https://ai.google.dev/pricing) for updated details. The workflow uses Gmail labels (e.g., youtube-viewers, sales-inquiry, meeting-request, potential-clients, collaboration-requests) for classification — make sure these exist in your Gmail account.

How it works

Chat Trigger: You interact with the agent via a chat interface (webhook). AI Agent: Gemini-powered assistant interprets your instructions (send, reply, label, delete, fetch emails). Email Actions: Based on your request, the assistant uses Gmail tools to act on emails (Send, Reply, Label, Delete, Get Many). Contact Lookup: If only a name is provided, the agent checks Google Sheets for the matching email address. If not found, it prompts you to add it. Memory: A buffer memory stores chat context so the assistant can maintain continuity across multiple interactions. Labeling: Emails can be auto-labeled for better organization (e.g., client inquiries, meeting requests).
