Send AI-Summarized Unread Email Alerts to Slack using GPT-4o and Gmail

Who is this for?

If you’re overwhelmed with incoming emails but only want to be notified about the essentials, this workflow is for you. Perfect for busy professionals who want a short AI summary of new emails delivered directly to Slack.

What does it solve?

Reading every email wastes time. This workflow filters out the noise by:

• Automatically summarizing each unread Gmail email using AI
• Sending you just the sender and a short summary to Slack
• Helping you stay focused without missing key information

How it works

• Every minute, the workflow checks Gmail for unread emails
• When it finds one, it:
  • Extracts the email content
  • Sends it to OpenAI’s GPT model for a 250-character summary
  • Delivers the message directly to Slack

How to setup?

1. Connect your accounts:
   • Gmail (OAuth2)
   • OpenAI (API key or connected account)
   • Slack (OAuth2)
2. Edit the Slack node:
   • Choose the Slack user/channel to send alerts to
3. Optional: Adjust the AI prompt in the “AI Agent” node to modify the summary style
4. Optional: Change polling frequency in the Gmail Trigger node

How to customize this workflow to your needs

• Edit the AI prompt to:
  • Highlight urgency
  • Include specific keywords
  • Extend or reduce summary length
• Modify the Slack message format (add emojis, tags, or links)
