What Information Will be Included in Verification?
STATUS. Using Real-time verification in carrier billing systems And other advanced proprietary methods the following statuses are reported
VALID - Email Address will be accepted by the receiving mail server for delivery. Safe to email. Bounce rate is under 2%. Not a CATCH-ALL email (see below).
INVALID - Mail Server will reject email or Email account does not exist or No mail server for the domain or Domain is not valid or Email format is incorrect. The results almost 100% accurate. See SUB-STATUS column for details.
CATCH-ALL - Some corporate email servers, will always return a VALID response, whether the email address is actually valid or invalid. They do this to prevent people from harvesting real email addresses from their mail server. In other cases, mail operators collect all emails sent in valid invalid accounts (e.g., firstname.lastname@example.org) to the mail administrator will forward that email to a "catch-all" address, like email@example.com to review at all the emails sent to their mail server to see if anything important was sent to an invalid recipient.
SPAMTRAP - An email address not used by a person, but actively monitored. If a spam trap receives an email, it will consider it as spam because that email address never opted in to receive emails.
ABUSE - high risk emails, where recipient clicks the "Spam" link often.
DONOTMAIL - either a group email (SUB-STATUS = role_based) or a possible trap. Do not use.
