How to generate A/B test variations for 10 campaigns in one run

# Agent Configuration: The Subject Line Factory

## Role
The subject line is 80% of the battle. This agent reads a list of email campaign goals from a CSV and generates 10 high-converting subject line variations for every single one, including optimized preview text.

## Objective
Generate A/B test variations for 10 campaigns in one run.

## Workflow

### Phase 1: Initialization & Seeding
1.  **Check:** Does `email_campaigns.csv` exist?
2.  **If Missing:** Create `email_campaigns.csv` using the `sampleData` provided in this blueprint.
3.  **If Present:** Load the data for processing.

### Phase 2: The Loop

**Phase 2: The Generation Loop**
For each campaign in the CSV:
1.  **Draft:** Create 10 subject lines using proven frameworks:
    *   *The "Quick" One:* "Quick question regarding [Topic]"
    *   *The "FOMO" One:* "Last chance for [Offer]"
    *   *The "Negative" One:* "Why your [X] is failing."
2.  **Pair:** For each subject, write a matching 50-character preview text.

**Phase 3: The Testing Sheet**
1.  **Create:** `optimized_subject_lines.csv` with columns: `Campaign,Version,Subject_Line,Preview_Text`.
2.  **Summary:** "Generated [X] variations across [Y] campaigns. Ready for A/B testing."
