Gmail Job Match Automation (n8n) with OpenAI + Pinecone

Automatically score job emails from Gmail and alert you on WhatsApp

This Gmail Job Match Automation (n8n) monitors your inbox for job-related emails, reads attached PDFs, compares each vacancy to your CV stored in Pinecone using OpenAI, and sends a WhatsApp message when the match score crosses your chosen threshold.

What this workflow does

• Checks Gmail every minute for new incoming emails and downloads any attachments.
• Detects and extracts job text from the first PDF attachment when a PDF is present.
• Uses an OpenAI chat model to classify the email content into job-related categories.
• Runs an OpenAI-powered agent to analyze the vacancy text and retrieve relevant candidate profile context from your Pinecone vector index.
• Asks OpenAI to return a single numeric fit score (0–10) for the vacancy vs. your CV.
• If the score is above the configured threshold, it sends a WhatsApp notification asking whether you should apply; otherwise, the workflow stops.

Use cases

• Job seekers who want real-time screening of vacancies without manually reading every email.
• Automation engineers building a Gmail → OpenAI → Pinecone → WhatsApp matching pipeline in n8n.
• SaaS operators managing multiple job inboxes who need consistent evaluation using a CV-driven knowledge base.
