n8n Workflow: Triage Gmail Feedback to Deduped Linear Issues

Turn unread Gmail feedback into deduplicated Linear issues—automatically

This n8n workflow watches your Gmail inbox for unread customer feedback, uses OpenAI to triage and deduplicate against your existing Linear issues, then creates a new issue or updates the right one—without double-triaging.

What this workflow does

• Runs continuously and on schedule: triggers every minute for new unread Gmail messages, and also runs every Monday morning.
• Cleans incoming emails: removes replies/quotes and ignores auto-replies, newsletters, mailing lists, plus configured sender/subject patterns (and skips the workflow’s own outgoing messages).
• Loads Linear context: retrieves the team’s open Linear issues (including comments) and avoids reprocessing if the email was already filed using a stored message marker.
• Uses OpenAI for triage + deduping: applies an OpenAI chat model with a structured output schema and a Linear search tool to classify each email as: a new issue, a match to an existing open issue, or unclear.
• Validates the decision: checks confidence thresholds and only then performs the selected action.
• Handles the outcome: creates a new Linear issue, adds a comment to a matched issue, or asks the customer for clarification when the email is unclear. It embeds the email marker for future deduplication.
• Closes the loop via Gmail: sends a thank-you or follow-up question, and marks emails as read after handling. If triage is held due to Linear/API or AI issues, it emails the team.
• Weekly ranking report: on Mondays, ranks open Linear issues by the number of customer-request markers they contain and emails the top results to the team.

Use cases

• Convert customer feature requests and bug reports from Gmail into accurate, deduplicated Linear issues.
• Prevent duplicate issues by matching new feedback to existing open items and commenting instead of creating duplicates.
• Get a weekly view of which Linear issues are being requested most by customers.

Technical details
