I've been working with our data team to clean out invalid emails. There is one person that Marketo noted as invalid, because it bounced with this reason "554 delivery error: dd This user doesn't have a aol.com account [-9] - mta4129.aol.mail.bf1.yahoo.com"
To me, this bounce reason sounds like the email does not exist. However, BriteVerify says it's a valid email.
Does anyone have insight on this bounce code and why BriteVerify might think it's a valid email?
