We have the need to send to all of our faculty, staff and students from time to time. Around 100,000 people. What I have been doing is creating 10 lists with around 10K people on each. Each list has a different prime time. One starts at 11 p.m, next one at midnight, then 1 a.m. etc. This way we don't cripple our e-mail system. Is there a better way to do this? Building 10 lists and sending the mail to them is a bit of a nuisance. Would rather have on list with 100k and have some system trickle the mail out overnight.
