A spam-trap is a honeypot used to collect spam.
Disposable – don’t send
Disposable emails are fake accounts used to avoid using a real account.
Accept-All – safe
It’s a catch-all address is used to ensure a company receives any email that has been sent to them, regardless of typos. Example [email protected] is correct by if typed as s[email protected] it will get there, but its unknown who if anyone will ever see it.
Valid – safe
A valid email address has been verified as a real email that is currently accepting mail.
Invalid – don’t send
Its verified as a bad recipient address that does not exist or is not accepting mail. Invalid emails will result in a bounce.
This email appears to be OK, however the domain and/or server is not responding to our requests. This may be due to an issue with their network or expired domain names. Unknown addresses are checked 3 times before the result code is given.
Role – safe
This email is a role-based email address ([email protected], [email protected], [email protected], [email protected]) and is not associated with a particular person, but rather with a company, department, position or group of recipients
