## status

* `valid`:  The recipient’s mail server has confirmed that the email address is valid and safe to send to.
* `invalid`: The email address is either incorrect or does not exist, meaning it cannot receive mail.
* `risky`: This email address may have quality issues, potentially leading to bounces or low engagement. Risky categories include Accept All, Disposable, and Role-based addresses.
