This n8n workflow automates the process of sending personalized daily, weekly, or surprise factoid emails to subscribers, integrating Airtable, Gmail, and AI content generation. The process begins with user subscriptions through a form, storing preferences in Airtable. A scheduled trigger runs daily at 9 AM, searching for subscribers based on their interval preferences. For each subscriber, an AI agent generates a unique factoid related to their chosen topic, and an image is created to complement the factoid. An email is then composed and sent with the AI-generated content, along with an unsubscribe link. The workflow also handles unsubscriptions and logs the last sent date in Airtable for tracking. This setup is ideal for content creators, educational services, or community managers aiming to engage their audience with automated, personalized learning content.
