@abcd12356 1) The recipient_status column provides the status of the delivery of the message to the recipient. If the message was sent to multiple recipients, it will show all the recipients and the corresponding status against each, in the format: ##.
For example, ##Receive, Send means that the message was received by the service and sent to the intended destination. ##Receive, Fail means that the message was received by the service but failed to be delivered to the intended destination. ##Receive, Deliver
means that the message was received by the service and delivered to the recipient’s mailbox. 2) With regard to input criteria, you can provide the date and time range in which to search for message events. We do not offer search by message subject (is this
what you meant by title?) at this point.
