The Sent data view contains records of all emails that have been sent, including details such as JobID, EventDate, and other relevant information. To gather the required information about emails deployed in the last seven days, the Sent data view should be used.

Query Example:

SELECT JobID, EventDate, COUNT(*) as SentCount FROM _Sent WHERE EventDate >= DATEADD(day, -7, GETDATE()) GROUP BY JobID, EventDate
