This resource defines Targeted Email statuses after finalising an email and can help confirm if a message has been sent successfully.
To learn more about the targeted email tool, check out An Overview of Using Targeted Emails.
Scheduled
If the email is set to be sent at a future date/time, the status will be "Scheduled" until the scheduled date/time arrives.
Sending
A status of "Sending" means that the email is in the process of being sent. The status will not change to "Sent" until all recipients have received the email.
Sent
When the status changes to "Sent", this confirms that an email has been sent successfully to all designated recipients.
