I am trying to send out an immediate delivery, but I am receiving the following error message stating it is not in the correct state.
"The delivery record is not in the correct state. Please contact support."
The error message may occur because a delivery is attempted while the email delivery is already in a calculating state. The error occurs when a delivery is not ready to send, but is pushed to the queue by the send action. Keep in mind it will not actually send, until it is done calculating. The audience calculation can take a some time if the audience is large.
