An uncertain email attempt needs review before you try another send.
1. Keep the attempt details
Open the affected document and find the delivery attempt in History. Note its reference, time, intended recipient, and visible status.
2. Distinguish the outcome
Queued, accepted, blocked, and unknown are different results. Preview, Copy Link, Download, or Mark as Sent does not establish that an email was delivered.
3. Request review
Use Human Support with the document number and attempt reference if the outcome remains unknown. Avoid changing the recipient or sending the same message repeatedly while it is being checked.
4. Act on the confirmed result
After the outcome is established, use the appropriate supported retry or an agreed individual follow-up. Check the new result in History.
