## Best Practices

<Tip>
  **Consider unsubscribing instead of deleting**: If you want to stop sending emails to a subscriber but keep their data for analytics, use the Update Subscriber endpoint to set their status to `unsubscribed` instead of deleting them.

### When to Delete vs Unsubscribe

| Action          | Use Case                                                          |
| --------------- | ----------------------------------------------------------------- |
| **Delete**      | GDPR/data deletion requests, duplicate records, test data cleanup |
| **Unsubscribe** | User opts out, temporary pause, compliance requirements           |
