Send AI-Generated Emails via Telegram with GPT-4o-mini & Gmail

This beginner-friendly n8n workflow turns your Telegram bot into a personal AI-powered email agent. Users send a message to the bot, and it uses GPT-4o-mini to automatically generate structured email content—including recipient, subject, and body—then sends it via Gmail, with confirmations replied back in Telegram.

The workflow flow is straightforward: A Telegram Trigger captures incoming messages. An AI Agent powered by OpenAI processes the natural language input into email format, supported by a Memory Node for short-term conversation context per user chat ID. The Gmail Node dispatches the email, and a final Telegram Node provides status updates, creating a seamless ChatGPT-like experience within Telegram.

Benefits include massive time savings for mobile email drafting without opening Gmail apps, integration of AI for intelligent content generation, and easy setup for productivity boosts. Use cases: Professionals dictating emails on the go, virtual assistants for teams, or automating responses in customer support—perfect for anyone wanting AI-enhanced messaging without complex tools.

Setup is simple: Create a Telegram bot via BotFather, add OpenAI API key (GPT-4o-mini recommended), configure Gmail OAuth, activate the workflow, and start chatting with your bot.
