Write a very fast bit of code (multi-threaded probably) and hope your mail server can cope - and it doesn't think it's spam

If you try to send thousands of emails within a very short period of time, your email server will probably block it thinking someone is trying to overload it. You can probably split your users into batches and try to send emails through different email servers.

I doubt any CMS system will even attempt to email 100,000 people in an hour. If you have to email that many people then you will probably need to do as I suggested in my first reply, and multi-thread, probably to different mail servers. If you are using a 3rd party host then you are probably not going to acheive it anyway as they will treat it as a DOS attack.
