Unknown is not invalid. A confirmed mailbox does not guarantee delivery. Original columns are retained only for the file checked in this session.
Task details & recovery
Accepted tasks continue after closing this tab. Reopen them from Recent checks. A recovery file also groups multi-batch checks and import settings; it contains no API key or original rows.
To use a recovery file, start a new list, select the same original file and email field, then load the recovery file. Remaining unsubmitted batches are not restarted automatically.
