The monthly Executive Report usually goes out between the 1st - 3rd days of each month.
The weekly Executive Report sends out on Mondays.
The Executive Report may send outside of business days as it recognizes the start of each month, not specifically Monday-Friday.
Accounts with active products generally trigger Executive Reports to be sent, however, for accounts with only Listing Builder active, users will not receive any Executive reports if they don't have any changes in data as changes in the data are needed for a new executive report entry.
