Hi, Delivery logs are synced asynchronously between enhanced MTA and
Campaign instance. Please wait for 2-3 days to see if any of these
proofs broadlog get marked as failed. If it doesn't then it would mean
that the delivery was received correctly by the recipient domain MX
server but due to some issue the MX server has not delivered it in
Inbox. Check with the MX domain administrator and check the recipient's
SPAM folder. Thanks, Deepika
