Customer Feedback Loop Analyzer (n8n Automated Workflow)
Customer Feedback Loop Analyzer (n8n Automated Workflow) This workflow automates the process of collecting customer feedback from forms and emails, analyzes it using AI, classifies it by category and sentiment, logs it into Google Sheets, and routes it to the right communication channels like Slack or email. It closes the feedback loop efficiently by ensuring every review is categorized, tracked, and acted upon. Who’s it for Product managers wanting structured customer insights Customer support teams needing fast issue routing Engineering teams who want to be alerted to bugs quickly Growth & UX teams tracking feature requests and usability feedback Any business managing customer feedback at scale How it works Form submission trigger captures reviews submitted via customer review forms. Gmail trigger listens for new feedback emails. Extract details (Code node) parses sender details and extracts the actual review text. AI node (LLM) summarizes the feedback, determines sentiment, and classifies it (Bug, Feature Request, UX Issue, Other). Google Gemini (optional) provides advanced classification/summarization. Google Sheets node logs all structured feedback for historical tracking. Switch node routes feedback into separate flows by category. Slack node instantly notifies the team of critical feedback (e.g., Bugs). Email node sends reports to relevant stakeholders (e.g., Feature Requests to product managers). How to set up Import the workflow JSON into your n8n instance. Connect credentials for: Gmail (for receiving/sending feedback) Google Sheets (for logging reviews) Slack (for real-time team alerts) Configure your Google Sheet (columns for Date, Reviewer, Sentiment, Category, Feedback).

Requirements n8n (cloud or self-hosted) Gmail API access (OAuth2 connected in n8n) Google Sheets API access Slack webhook or OAuth connection (Optional) Google Gemini or another LLM integration How to customize Modify the AI prompt to classify into different categories (e.g., “Support Issue”, “Billing Problem”). Extend the Google Sheet schema to include product version, tags, or priority scores. Add a translation step if feedback is multilingual. Replace Slack notifications with Teams/Discord if needed. Connect to Jira or Trello to auto-create tasks for certain categories. Add-ons Sentiment-based alerts**: Trigger Slack notifications only if sentiment is negative.
