Below is a list of category definitions mailfloss uses to identify email addresses.
Invalid
These emails fail syntax checking and are invalid.
Spam
These email addresses are flagged as spam accounts.
Role
Emails are of role, such as administrator. Although they may be valid, role emails tend to perform poorly and may affect deliverability rates.
Banned
Emails belonging to a banned keyword or domain. These are swear words and others that tend to be fake and perform poorly.
Disposable
These emails are from disposable email services that are temporary. They are not worth emailing and will affect deliverability.
Illegitimate
The domains of these emails do not have valid mx records and thus do not accept emails.
Available
The domains are available and the emails are likely old and invalid.
Unverified
The emails appear to be good but we could not verify because the domain is not responding.
Blacklisted
Emails contain blacklisted keywords defined by the user.
Bounced
Emails sent to this address hard bounce and should not be emailed.
Accept All
These email addresses at this domain look good, but any email address at this domain look good and cannot be verified completely.
We’re continually refining our processes and algorithms. If you feel we’ve miscategorized some of your emails, please get in touch. If you are doing a manual floss, you can report the mistake by clicking on the “Report as Incorrect” button.
