Core Problems Addressed
- Manual management of subscription lists is cumbersome and difficult to automate personalized content delivery

Main Process Steps
- Users submit subscription requests via the “Subscribe Form,” providing their email, topics of interest, and preferred delivery frequency.
- The system stores or updates subscription information in the Airtable database.
- A scheduled trigger runs daily at 9 AM, querying Airtable for active subscribers in the “daily,” “weekly,” and “surprise” frequency categories.
- For “surprise” frequency users, a random logic determines whether to send content on that day.
- For eligible subscribers, a sub-workflow is invoked:
- The Groq language model retrieves topic information from Wikipedia and generates unique knowledge factoid text.
- OpenAI generates corresponding illustrations and adjusts image dimensions.
- Email content is assembled, including text, images, and an unsubscribe link, then sent to users via Gmail.
- After sending, the “Last Sent” timestamp is updated in Airtable to ensure frequency control.
- Users can submit unsubscribe requests via the “Unsubscribe Form,” upon which the system marks their status as “inactive” and stops future emails.
- A confirmation email is sent to new subscribers to enhance engagement.
