I have a quite big site with more than 7100 subscribers. I had contacted my hosting company and they changed “Max emails per hour” to 25000.
But Delivery engine still is sending only 284 mails per 5 minute, so sending newsletter to all subscribers tooks me about 125 minutes.
With “Max emails per hour” = 25000 it should be less than 20 minutes.
What should I change if I want to use “full power” of my server?
