You have email recipients included in an email list that are reported as an invalid account and would like to remove these accounts from your email lists.
Email addresses that are returned as an invalid account will not receive email from NetCommunity unless we mark the invalid account as valid. These recipients will still show in the list but NetCommunity will not send to them. When you view the email message report you will see them as a recipient but will not see data in the sent column.
If you are looking to remove the recipient from the list alltogether, this can be accomplished by editing the query associated with the list or replacing the imported list.
