Valid email addresses should conform to established IETF standards. We check for this via a syntactic email validation engine.
Email addresses used for business purposes are more likely to be branded and include a company's name.
Chances are disposable email service providers do not supply valid email addresses. Mostly users with short-term needs use temporary email addresses.
Valid email addresses should have a corresponding domain name with configured MX records. If not, these addresses might be inaccurate.
A valid email address should be able to receive messages. Our email verification products check for mailbox existence via email-sending emulation and SMTP connection checks.
It’s unlikely for valid email addresses to be catch-all ones since these are not designed to reach a designated person.
