## Rollback Plan
If issues occur after deployment:

1. **Rollback Kubernetes Deployment**
   ```bash
   helm rollback brand-master --namespace my-apps
   ```

2. **Rollback Database Migration**
   ```sql
   -- Reverse changes manually or restore from backup
   DROP INDEX IF EXISTS idx_contact_message_status;
   DROP INDEX IF EXISTS idx_contact_message_is_read;
   DROP INDEX IF EXISTS idx_contact_message_created_at;
   
   ALTER TABLE contact_message DROP CONSTRAINT IF EXISTS check_status;
   ALTER TABLE contact_message DROP COLUMN IF EXISTS admin_notes;
   ALTER TABLE contact_message DROP COLUMN IF EXISTS status;
   ALTER TABLE contact_message DROP COLUMN IF EXISTS is_read;
   ALTER TABLE contact_message DROP COLUMN IF EXISTS phone;
   ALTER TABLE contact_message RENAME COLUMN full_name TO name;
   ```

7. Bulk actions support
8. Message archiving system
9. Integration with CRM systems
10. Analytics dashboard for message trends
