I've seen the opposite questions asked a few times, but haven't found anything addressing this side of the issue. When sending a newsletter out to a large list (>5,000), how fast does aMember pass the personalized messages over to the SMTP server? I have a VPS and broadcast speed is not limited, except by configuration and software logic. The reason I ask is to see if I need to use the ListMail integration plugin or if I can depend on aMember's internal system. ListMail can easily send 10-15 personalized emails to the SMTP server per second.
