## Behavioral notes
- The type uses the library email-validation rules and environment settings to evaluate address validity.
- Public properties expose the stored email address and related state as a contact-info value object.

## Constraints and usage notes
- Validation behavior depends on the configured email-validation service and environment settings.
- Consumers typically use the class as part of higher-level contact-information models.
