Summarize Gmail Support Emails with Gemini and Post to Slack

This workflow automatically checks your Gmail inbox for new support emails, summarizes them using Google Gemini and posts concise summaries directly into Slack. Instead of manually reading long support emails, your team can stay updated with short, actionable insights in real-time.

Who’s it for

• Customer Support Teams – to stay on top of support tickets without reading lengthy emails.
• Operations Managers – who need quick insights on issues raised by customers.
• Engineering Teams – who want alerts and summaries of support escalations in Slack.
• Founders/Execs – who prefer high-level summaries rather than full email threads.

How it works

1. Gmail Trigger – Check Support Emails

   • The workflow runs every minute to detect new incoming emails in your support inbox.

2. Forward Email to Gemini for Summarization

   • Extracts the email body and prepares it for the LLM model.

3. Gemini – Summarize Support Email

   • Google Gemini condenses the email into a short, clear summary.

4. Slack – Post Summary to Channel

   • The summarized text is sent to your chosen Slack channel for instant visibility.

How to set up

1. Connect your Gmail account in n8n.
2. Configure the Gmail Trigger to check emails from your support inbox (or apply filters like subject = “Support” or label = “Support”).
3. Add your Google Gemini API credentials in n8n.
4. Configure Gemini with a summarization prompt (e.g., “Summarize this email in 3 bullet points”).
5. Connect your Slack account and select the target channel.
6. Save and activate the workflow.

Requirements

• n8n instance (self-hosted or cloud).
• Google Account with Gmail API enabled.
• Google Gemini API access (API key).
• Slack workspace with a bot token and permission to post messages.

How to customize

• Change the email filters in the Gmail Trigger (e.g., only unread emails, only with label Support).
• Modify the summarization style in Gemini (bullet points, short paragraph, etc.).
• Choose a different Slack channel for posting (e.g., #support, #alerts, #dev-team).
• Add additional nodes for logging into Google Sheets or creating Jira tickets.

Add-ons

• Save original emails + summaries into Google Sheets for tracking.
• Create Jira or Trello tasks automatically for high-priority issues.
• Add a translation step if support emails arrive in multiple languages.
• Integrate with Zendesk or Freshdesk if you also use those tools.
• Integrate OpenAI LLM models.

Use Case Examples

• Customer sends a bug report → Gemini summarizes key points → Slack post alerts dev team instantly.
• Support email with long back-and-forth conversation → condensed into a 3-line summary in Slack.
• Team lead checks Slack daily instead of logging into Gmail to stay informed.
