What checks are performed to verify an email?

No Más Rebotes runs four main types of email checks without actually sending an email:

1. Syntax: confirms the format is valid (for example, name@domain.com).
2. Domain: checks that the domain exists and is registered correctly.
3. Mailbox: pings the mail server to confirm the mailbox is active and can receive emails.
4. Risky email detection: identifies the types of emails that are less likely to be delivered or carry a higher risk of spam complaints (for example, disposable emails and catch-all domains).
