AI Email Subscription Workflow Automation 

AI Email Subscription Workflow Automation 

In this guide, we’ll walk through a real-world AI email subscription use case that sends factoids tailored to each subscriber’s interests. The workflow uses AI to generate fresh text, create custom illustrations, and send emails automatically—without human intervention.

What This AI Email Subscription Workflow Does

This AI email subscription workflow handles the full cycle—subscriber signup, automated content generation, image creation, email delivery, and unsubscribe management—while maintaining accuracy and personalization.

Here’s how it works:

1. Subscription Management

Subscribers join via a simple n8n form:

  • Enter email address
  • Select a topic of interest
  • Choose delivery frequency: Daily, Weekly, or Surprise Me
  • An unsubscribe form is available to instantly stop emails.

2. Scheduled Sending

Every day at 9 AM, the workflow checks Airtable for:

  • Active daily subscribers
  • Weekly subscribers who haven’t received an email in 7+ days
  • Surprise subscribers (selected at random)

3. AI-Powered Content Generation

An AI agent:

  • Creates a fresh, unique factoid on the chosen topic
  • Pulls extra context from Wikipedia if needed
  • Ensures no duplicate factoids are sent

4. AI Image Creation

A second AI model:

  • Generates a child-friendly illustration matching the factoid
  • Resizes the image for perfect email display

5. Email Assembly and Delivery

The workflow:

  • Combines factoid text, illustration, and an unsubscribe link
  • Sends the email via Gmail directly to the subscriber

6. Logging and Updates

After sending, Airtable is updated with:

  • Last sent date
  • Subscriber activity logs

7. Concurrent Email Processing

Using subworkflows:

  • Multiple emails are sent in parallel
  • A failure in one email doesn’t block others
