To begin with, you should have separate tables for different types of data:
1. Customer Table: This should include fields like CustomerID, Name, Email, Subscription Status, and Preferences. 2. Email Campaign Table: Fields could include CampaignID, Subject Line, Content, and Send Date. 3. Interaction Table: This table should log interactions like opens, clicks, and unsubscribes. Fields might include InteractionID, CustomerID, CampaignID, and Interaction Type.
Properly structuring these tables allows for efficient querying and reporting, crucial for performance metrics and A/B testing.
