Quick overview
Quick overview This workflow monitors incoming Gmail messages from suppliers, uses Google Gemini to analyze sentiment and relationship risk, generates an engagement strategy for risky emails, sends an alert to Slack, and logs the analysis and recommended response to Google Sheets. How it works Triggers every minute by checking Gmail for new incoming emails. Filters out irrelevant messages (for example newsletters, unsubscribe emails, no-reply senders, and auto-replies) and keeps only valid supplier emails. Extracts the sender, subject, and email snippet into a single text block and waits briefly to buffer processing. Sends the email text to Google Gemini to return a structured JSON analysis with sentiment score/label, intent, urgency, key concern, and deterioration risk, then normalizes these fields and derives a trend. Flags the interaction as high risk based on the deterioration risk value or a low sentiment score and waits briefly before continuing. Uses Google Gemini to generate a concise engagement strategy (recommended action, draft opening message, and follow-up timeline), then parses it and formats a Slack-ready alert. Sends the alert to a selected Slack user and appends the full analysis and strategy to a Google Sheets log for historical tracking. Setup Connect your Gmail OAuth2 credentials and ensure the Gmail Trigger is monitoring the mailbox that receives supplier emails. Add a Google Gemini (Google PaLM) API credential for the two Gemini steps (analysis and strategy generation). Connect your Slack OAuth2 credential and select the user/channel destination for the alert message. Connect your Google Sheets OAuth2 credential and update the target spreadsheet and sheet tab where the workflow appends the interaction log.
