Hi there. I am currently using phplist for one of my websites build on the wordpress, but it doesn't want to send more than 550 messages per hour and trust my I tried plenty of configurations to speed this up but without any luck. I have many lists on that website and need to be able to allow people to subscribe to multiple lists at the same time. Can you suggest something reliable? What are your experiences, did you send more than 2000-3000 emails at one in 1 hour? Thanks for your help...
