Our 4-Step validation process identifies harmful records
Email Validation Statuses
Spam Trap– These emails are unsafe to send in bulk and are either a known complainer or not associated with a real person.
Valid– These emails are associated with a real person and have been confirmed by the recipient’s email server.
Invalid– These emails are either malformed, the domain doesn’t accept email, or the recipient’s email server reports the email address is bad.
Catch All– These email addresses cannot be validated, just the domain, because the recipient’s server returns no credible deliverability information.
Deterministic – These are Catch All email addresses but we add a layer of confidence that the email was once delivered successfully.
Unknown – Not enough information was given to validate this email address. It could be the server wasn’t taking requests or taking too long to respond.
