n8n Workflow: Triage Gmail Brand Deal Emails w/ OpenAI

Turn unread Gmail brand deal emails into drafts, pricing, and Slack alerts—automatically

This n8n workflow monitors your unread Gmail inbox for potential brand deal opportunities, uses OpenAI to classify and extract deal details, verifies the brand with Tavily, then drafts a negotiated reply and logs everything to Google Sheets with a Slack notification.

What this workflow does

• Polls Gmail every 5 minutes for unread messages in your Inbox.
• Uses OpenAI to detect sponsorship/brand deal emails and extract key terms such as deliverables, offer amount, usage rights, exclusivity, deadlines, and potential scam signals.
• Skips low-confidence or non-deal emails to reduce noise, and applies a dedicated Gmail label to emails identified as brand deals.
• Runs a Tavily search for brand funding/background and prior creator campaigns, then uses OpenAI to generate a concise brand profile and legitimacy assessment.
• Calculates suggested rates and negotiation strategy (including counter-offer amounts) based on your audience metrics, deliverables, and requested terms (usage rights, exclusivity, timeline).
• Drafts an email reply with OpenAI—or sends a verification request for suspicious deals—and saves it as a Gmail draft in the original thread.
• Appends a deal log to Google Sheets and posts a summary (including a Gmail thread link) to a Slack channel.

Use cases

• You receive frequent sponsorship emails and want faster deal triage without manually researching brands.
• You want consistent pricing and negotiation based on deliverables, exclusivity, and timelines.
• You need real-time Slack visibility and a spreadsheet record for every validated opportunity.
