n8n Webhook Triage: OpenAI, Slack, Gmail & Google Sheets

Auto-triage every website inquiry—route leads to Slack & Google Sheets, send support to Gmail, and ignore spam

This n8n Webhook Triage workflow receives your website contact-form submissions, uses OpenAI to classify each message, and automatically routes results to the right place. Sales leads are sent to Slack, logged in Google Sheets, and acknowledged by Gmail—while support requests are forwarded to your support inbox via Gmail. Spam gets no further action.

What this workflow does

• Receives website form submissions via a webhook (POST).
• Normalizes fields like name, email, company, message, and source, and records a timestamp.
• Returns a JSON response immediately to the form submitter to avoid waiting for downstream processing.
• Uses an OpenAI text classifier to label the inquiry as: Sales lead, Support request, or Spam.
• Sales lead routing: posts an alert to a Slack channel, appends lead details to Google Sheets, and sends an acknowledgment email via Gmail.
• Support request routing: forwards the message to your support inbox via Gmail (with the sender set as reply-to).
• Spam handling: takes no further action.

Use cases

• SaaS teams that want instant lead alerts and tracking when users submit contact forms.
• Support teams that need automatic routing of inbound requests to a Gmail inbox.
• Operators who want to reduce manual triage by filtering spam and categorizing inquiries in real time.
