Sorry to bother you. I have just been setting up a new e-mail to be sent out along with one that was already in the queue.
I would like the e-mails, from the two, to be sent out randomly i.e. rather than having the queue process all messages from one e-mail and then move on to the next, I would like messages from each e-mail in the queue to be sent out. One message from e-mail one, one message from e-mail two... etc.
According to this page https://docs.acymailing.com/setup/configuration/queue-process there should be a 'Order the send process by' setting but we do not seem to have this. We're running AcyMailing Essential 8.6.2
