Check whether the PDF finished#

1
Open the source record and find Document Delivery & PDF. Try Download PDF and wait if the file is still being prepared.
2
If an email failed, check the recipient and status in that card's delivery list.
3
Confirm Send Email is available on your plan before trying again.
4
Preview the document and check the recipient address and send history.
5
Retry only after correcting the specific address or document problem.

A generated PDF and a delivered email are separate outcomes.

Review the email delivery#

Download and inspect the current PDF version before resending. Keep the failed delivery record for support.

WARNING: Do not treat a send request as proof of successful delivery. Preserve the failed delivery record for investigation.
