Cron questions running a 13000 email list

My list has 13000 emails. Recently the server load has been spiking. My host recommends these settings and running a cron job every 10 minutes.

MAX_PROCESS_MESSAGE = 1000
MAILQUEUE_BATCH_SIZE = 1000
MAILQUEUE_BATCH_PERIOD = 3600
MAILQUEUE_THROTTLE = 2

I’m assuming the cron would always be running and start sending emails based on the embargo date and time? Or is there a way to start and stop it automatically?

I answered my own question. Running the cron all the time doesn’t use any resources per my host.

I have a list with over 150,000 emails and we run it all the time at 10 minute intervals and it doesn’t affect the load on our cloud servers at all. I shorten the run time by 10 seconds so it has time to reset before starting the next round.
