Campaigns and messages in campaigns can go through a series of states as the campaign goes on. These states represent the current status of the campaign to give you better insight.
What are the states that a campaign can go through?
In progress state:
Queued - This state indicates the campaign has been queued for send; it will begin sending shortly.
Sending - This state indicates the campaign has begun sending messages. The campaign will stay in this state for up to 3 days, depending on the size of the campaign (and whether issues are experienced, as explained further down)
Success state:
Completed - The campaign was sent; this state indicates that at least one of the messages sent was successfully delivered.
Failure state:
Failed - None of the messages for the campaign were successfully delivered.
