I have a Sendable Data Extension with thousands of records. Each record represents an email request and its properties values. I was looking for a way to get a unique id for each row, if any exists. I seesaw this and I think isthought it might be useful Autonumber in Marketing Cloud?
However as athe existence of a row is not a warrantyguarantee that the email has been sent, how can I match or confirm if an email request that exists in the sendable Data Extension was really sent or not? Is there any other SQL query I can run to filter the sent from the unsent? Is there any row column referring to the send status?
