Label Gmail inbox emails with GPT-4o and store them in Mem0

Who’s it for

This template is for small business owners like contractors, consultants, and agency owners who close deals via email.

How it works

Think of this as a 24/7 personal assistant for your inbox. Every five minutes, the workflow "reads" your new emails. It instantly filters out the junk (like newsletters or internal notifications).

The AI then analyzes the email to figure out what the customer wants. Then automatically puts a label on the email in Gmail (like "Action Required" or "Urgent"). Most importantly, it saves a "memory" of that email.

How to set up

Gmail: Connect your Gmail account using OAuth2 credentials. AI Models: Add your OpenAI API key to the GPT-4o node. JigsawStack: Provide API keys for JigsawStack (the optional fallback classifier) and Mem0.ai in the respective HTTP Header Auth credentials. Domain Filter: In the [Router]: Triage Streams node, update the second rule to match your company's domain (e.g., your-sme-domain.com) to filter out internal emails.

Requirements

n8n version 1.0+ Gmail OAuth2 Credentials OpenAI API Key Mem0.ai Account JigsawStack API Key (Optional but recommended for fallback)

This template as a foundation
