historique_messages

With accountRead only

Lists the messages already sent to customers, from newest to oldest, with their delivery report: received, customers with no screen (unreachable), failures, and still being sent. Also summarizes the automatic messages sent over the period (win-backs for lost customers, birthdays) and says whether a message can still go out today. Use it to know what was sent, check that a send was delivered, or before writing a new one.
