n8n Workflow: Gmail Competitor Newsletters to Telegram Alerts

Get competitor newsletter signals in Telegram—only when they’re worth acting on

This n8n workflow monitors your Gmail competitor newsletters, uses Google Gemini 3.5 Flash-Lite to score and classify commercial signals, and then sends a formatted Telegram alert only when the message meets your configured alert threshold. No noise—just the competitor insights that matter.

What this workflow does

• Polls Gmail every minute for new emails matching label:Competitors.
• Builds an analysis prompt using the email sender, subject, and body, along with your configured importance threshold.
• Calls Google Gemini to extract a structured result (e.g., competitor, signal type, importance, evidence, and whether the item should trigger an alert).
• Filters results to alert only when the message is flagged as actionable and the importance score is >= your threshold.
• Formats a safe HTML message for Telegram and sends it to your specified chat.

Use cases

• SaaS competitive monitoring: Turn competitor newsletter mentions into actionable Telegram alerts.
• Product & growth teams: Detect signals like pricing changes, feature announcements, or market moves and route only high-importance items.
• Ops/automation engineers: Keep a lightweight, reliable pipeline from Gmail → Gemini → Telegram without manual triage.
