Understanding your agency's account mode.
Go to the Settings page.
Settings page is defaulted to General tab.
Find Account Mode field.
The Account Mode field is a drop-down list with two options: Simulate Send and Send Live.
The Send Live mode is, as the name suggests, operational and all messages are actually sent.
The Simulate Send mode is the same as Send Live mode short of sending the messages. Everything runs as if it is live except for the sending of messages; useful for operational checks.
Simulate Send mode allows you to see how the messages will look and when they are scheduled for delivery without dispatching them to be sent.
Simulate send event messages.
Simulate send auto message.
