The Automated Process:

1. Data Source: Fetches recipient data directly from Google Sheets
2. Validation: Automatically validates email addresses and checks contact history
3. AI Content: GPT-3.5 generates truly personalized emails with recipient's name, custom product introduction, and unique promotional offers
4. Delivery: Sends via SMTP with perfect formatting
5. Record Updating: Marks recipients as contacted in Google Sheets
6. Smart Timing: Implements random delays between emails to appear more natural and avoid spam triggers

The entire process runs automatically once configured, requiring only occasional oversight.
